Description

Composition for removing unwanted molecules

The present invention relates to compositions capable of removing unwanted molecules and also delivering perfume substances.

In response to the many demands for removing odors from clothing, living spaces, and limited indoor spaces, companies have applied various applications such as laundry detergents, fabric softeners, surface cleaners, kitchen detergents, deodorants, shampoos, hair conditioners, body products, and cancer removers. The purpose of this study was to be achieved through research. In many studies, an example of an effective removal material is the application of cyclodextrin (US6,878,695). The cyclodextrin is a polysaccharide having a cyclic structure in which 6 to 12 glucoses are linked by alpha-1,4 bonds. As an example of the most developed and applied cyclodextrin, alpha-cyclodextrin contains 6 glucose, in another example, beta-cyclodextrin contains 7 glucose, and as another example, gamma-cyclodextrin contains 8 glucose. and they all have a donut-shaped ring structure.

Specific bonds or structures between glucose allow cyclodextrins to have a rigid conical structure with a specific volume of voids. The “arrangement” of each interior space is formed by hydrogen atoms and oxygen atoms forming glycoside bridges. Therefore, the inner surface becomes very hydrophobic, and the specific shape and physicochemical properties of the interior have structural characteristics that can absorb organic molecules or parts of organic molecules that match the internal space of cyclodextrin or its derivatives. Therefore, when a formulation containing cyclodextrin is applied to the surface of an object, foreign substances such as off-flavor can be trapped in the internal space of the cyclodextrin to remove off-flavor. In addition, some fragrances in the product can be impregnated during the manufacturing process so that the fragrance is continuously released during use.

However, these cyclodextrins have a limited internal space size, so there are limited fragrance substances and odor substances that can be included. Also, when the formulation contains a water-soluble solvent such as water, the efficacy due to the poor solubility of the cyclodextrin Expression is limited. In particular, perfume materials with clopP of 3 or more and bp of 250 degrees or more, which are generally known to have excellent reverberation properties and good odor masking, have a problem in that there is a limitation in sufficient removal of odor substances and delivery of flavor substances by cyclic dextrin. In addition, cyclodextrin has low solubility, and derivatives have been developed to overcome this, and an example of cyclodextrin is a material in which some OH groups are substituted with an OR group, R is a methyl group or an ethyl group, or R is -CH ₂ -CH(OH)-CH ₃ or -CH ₂ CH ₂ -OH group, a form substituted with a hydropropyl group, or a cationic cyclodextrin having cationicity at pH, etc. exist in various ways.

The present invention relates to a material capable of compensating for the above problems of cyclodextrin used in the prior art for the removal of unwanted molecules, more specifically, for the removal of off-flavor, and capable of enclosing more various kinds of fragrance substances and off-flavor substances.

Therefore, the problem to be solved by the present invention is to apply a cyclic dextrin having a wider and various internal spaces of various sizes, and to remove more various unwanted molecules that could not be included in the conventional cyclodextrin, and more specifically, the removal of various odor sources. It is not only easy to use, but also allows for inclusion of a variety of hydrophobic and high molecular weight perfume substances that could not be incorporated in cyclodextrin.

In addition, the problem to be solved by the present invention is to apply a cyclic dextrin having a wider and various internal space, to export a fragrance substance encapsulated in the internal space of the cyclic dextrin, and to enclose the off-flavor source, thereby removing off-flavor. and compositions for delivering fragrance and methods for exhibiting.

In order to solve the above problems, the present invention provides a highly branched cyclic dextrin (HBCD) or a derivative thereof, comprising a fragrance and a solvent encapsulated in at least one inner space of the highly branched cyclic dextrin It provides a composition for removing unwanted molecules, characterized in that.

According to a preferred embodiment of the present invention, the highly branched cyclic dextrin is an alpha-1,6-glucosidic bond, in which 16 to 100 di-glucoses are linked. can be

In addition, according to another preferred embodiment of the present invention, the highly branched cyclic dextrin may have a dextrose equivalent value of 5 or less.

In addition, according to another preferred embodiment of the present invention, the solvent may include water.

In addition, according to another preferred embodiment of the present invention, the composition may further include a surfactant.

In addition, according to another preferred embodiment of the present invention, the composition may further include a water-soluble polymer.

It should be interpreted as meaning and concept consistent with the technical idea of the present invention based on the principle that there is. Accordingly, the embodiments described in the present specification and the configurations described in the drawings are only the most preferred embodiment, and do not represent all the technical ideas of the present invention, and thus various equivalents and It should be understood that there may be variations.

The present invention relates to highly branched cyclic dextrin (HBCD) or a derivative thereof, an unwanted molecule comprising a fragrance and a solvent encapsulated in at least one interior space of the highly branched cyclic dextrin It relates to a composition for removal.

The inventors of the present inventors have identified that the cyclodextrin used for removing off-flavor has a limited internal space and shape, so the included off-flavor or flavor is limited. Dextrin with a highly branched annular structure was devised to have internal spaces of various sizes. It was confirmed that such highly branched cyclic dextrin not only has significantly improved odor removal ability compared to conventionally used cyclodextrin, but also has a large molecular weight and hydrophobic fragrance material that cyclodextrin could not contain. The present invention was completed in anticipation of having more improved capabilities.

In the present invention, the unwanted molecule means an off-flavor source having an unwanted scent as an organic aromatic molecule. These odor sources may exist on the surface of fabrics such as carpets, kitchen countertops, dishes, floors, trash cans, ceilings, walls, carpets, household items such as air purifying filters, and surfaces such as skin and hair, and the present invention provides It is possible to remove molecules that do not, that is, the odor source. As this odor source, for example, substances such as (E)-5-methyl-2-hexenoic acid, 5-methyl-4-hexenoic acid, 6-heptenoic acid, isovaleric acid, 4-methylhexenoic acid, -ethyloctanoic acid are used in textiles. (Flavor and Fragrance Journal, 2012, vol. 27, 89-94), various studies on off-flavor components derived from the human body have been conducted (Anti-Aging Medicine, 2010, 7 (Anti-Aging Medicine, 2010, 7) 6): 60-65). Therefore, in the present invention, the off-flavor refers to a common off-flavor component that may occur in daily life, such as a normal human body origin, a textile origin, and is not limited to the above example.

The composition may exist as an emulsion/dispersion or as a clear single-sided solution.

In the case of removing odors from fabrics or the human body, the composition of the present invention is preferably a transparent single-sided solution, and should be transparent or translucent, preferably transparent, such as clear water.

In addition, when the composition of the present invention is used as a detergent, softening agent, shampoo, or surface cleaner, an emulsion/dispersion is preferred, and generally has a size of about 0.05 μm or more, preferably about 0.1 μm or more, more preferably about It may have an aggregate of micellar or vesicle molecules of 0.2 μm or more. Such a composition may be transparent, translucent, or opaque depending on the type and concentration of the material in the composition.

The composition of the present invention should be a composition capable of effectively delivering highly sited cyclic dextrin or a derivative thereof, and is not limited to the above formulation.

Hereinafter, the components of the composition for removing unwanted molecules will be described in more detail.

1) Highly branched Cyclic Dextrin (HBCD)

In general, cyclodextrins and derivatives thereof have been used in compositions for removing unwanted substances. Cyclodextrins contain 6 to 8 glucose, and they have a donut-shaped ring structure. These cyclodextrins have a specific bond or structure between glucose that allows the cyclodextrin to have a rigid conical structure with a specific volume of void space. The arrangement of each interior space is formed by hydrogen atoms and oxygen atoms forming glycoside bridges. Therefore, the inner surface has very hydrophobicity, and the specific shape and physicochemical properties of the inside allow cyclodextrin and its derivatives to absorb organic molecules or parts of organic molecules that match the space and shape, so that off-flavor substances can be removed. In addition, a fragrance that gives a fresh feeling is located within this specific internal shape, and if there is an off-flavor, it has a mechanism of substituting the fragrance and encapsulating it in the cyclodextrin.

The present invention was to supplement the limitations of cyclodextrin by applying a cyclic dextrin having a wider and various internal spaces, rather than a single spatial structure like the cyclodextrin.

The cyclic dextrin applied to the present invention is a highly branched cyclic dextrin. The highly branched cyclic dextrin is a glucose having a highly branched phase through an alpha-1,6 bond to a linear chain like amylopectin. The linkage of the chain of the polymer polysaccharide of becomes this

More specifically, the highly branched cyclic dextrin used in the present invention _{may be represented by (C 6} H ₁₀ O ₅ )xH ₂ O and is an odorless white powder oligosaccharide using alpha-di-glucose as a monomer. As an oligosaccharide, the average molecular weight is about 30,000 to 1,000,000 per mole (g/mol), and the polymerization degree is preferably 2500 glucose units. In addition, the dextrose equivalent (DE) value, that is, the reducing power of di-glucose, is preferably 5 or less. Also, preferably, di-glucose within 16 to 100 is linked by an alpha-1,6-glucosidic bond on the side chain to a linear chain consisting of alpha-1,4 bonds. . Through this bonding structure, highly branched cyclic dextrin has a cyclic alpha-glucan moiety (cyclic glucan pore).

As described above, when the highly branched cyclic dextrin according to the present invention meets the conditions such as the average molecular weight, equivalent value, and number of branched diglucoses, it is well soluble in water and has a flavor The collection capacity becomes more suitable.

In addition, the highly branched cyclic structure dextrin derivative refers to the highly branched cyclic structure dextrin derivative according to the present invention while maintaining the basic structure so as to obtain all the functions according to the present invention according to the structural features of the highly branched cyclic structure dextrin according to the present invention, and does not affect the function of the present invention. It refers to a structure in which an atom or group of atoms is substituted.

As such, the use of highly branched cyclic structure dextrin having a highly branched phase in the composition according to the present invention improved the ability to bind unwanted molecules on the surface treated with the composition, and the ability to bind unwanted molecules on the surface even at a lower concentration than the cyclodextrin derivative was improved. It is possible to more effectively reduce or eliminate non-existent molecules.

More specifically, with the structural features of the highly branched cyclic dextrin according to the present invention, it is possible to absorb various organic molecules or parts of organic molecules that match at least one interior space and shape of the highly branched cyclic dextrin. (to form a polymer), many foreign substances on the surface of the object, including unwanted organic molecules, including off-odor molecules, etc., can be accepted into the interior space. Therefore, the highly branched cyclic structure dextrin according to the present invention having various sizes of interiors can remove odors caused by organic aromatic molecules in a broad sense with various active groups, as well as excellent reverberation and good odor masking. It can usefully deliver a variety of flavoring substances with a clogP of 3 or greater and a boiling point of 250 degrees or greater.

In order for the highly branched cyclic dextrin to function functionally in the composition, at least about 0.1% to 20% by weight, preferably about 0.5% to 10% by weight, more preferably about 1% to about 1% by weight in the total composition. It may be present in an amount of 5% by weight, and when the content is included, it can be said that it is effective not only to remove odors but also to deliver fragrance components.

2) Spices

The perfume according to the present invention is present in inclusion in at least one cyclic structure of the highly branched cyclic structure dextrin to form a stable composition. The stable composition of the present invention provides the emotional quality of a good fragrance, which gives a fresh feeling by removing foreign substances, that is, off-flavor when treated on the surface of fabrics, human body, etc. In the present invention, the fragrance may provide at least a lasting fragrance.

The fragrances that can be encapsulated in the highly branched cyclic structure dextrin according to the present invention are characterized in that they can encapsulate various fragrances regardless of hydrophilicity or hydrophobicity. It can be seen that various fragrances can be included by including not only fragrances that can be included, but also fragrances that cannot be included in cyclodextrin. That is, the fragrance included in the highly molecular cyclic structure dextrin according to the present invention is not limited to a specific fragrance, and it is characterized in that it has the ability to include various fragrances.

On the other hand, the fragrance ratio of the fragrance is the ratio of the alcohol to the perfume stock solution, and the fragrance fragrance ratio of the fragrance according to the present invention is about 0% to about 3% of the total composition, preferably about 0.003% to about 2%, more preferably is from about 0.005% to about 1%.

In the present invention, a fragrance is added to eliminate off-flavor and to make the smell last longer on the surface. When a strong fragrance is required, a fragrance having a high fragrance ratio or a fragrance having an excellent reverberation feeling may be applied. Any kind of fragrance may be applied to the composition of the present invention, and the fragrance component may be hydrophobic or hydrophilic.

In order for the fragrance to last longer, the fragrance must have at least partially hydrophobicity and a relatively high boiling point. That is, incense mainly consists of fragrance raw materials belonging to the following two groups. (a) ClogP 3 or more, preferably 3.5 or more, and (b) 205 or more, preferably 210 or more, more preferably 220 or more.

Since the properties of the perfume components have various isomers and have a large influence on substances existing in the vicinity, it is not easy to clearly distinguish them with numerical values such as ClogP and molecular weight, which are physical properties. Therefore, the numerical values described above are approximate values for indicating the properties of the fragrance, and should be interpreted flexibly in the interpretation of the numerical range.

For these hydrophobic perfumes, the weight ratio of perfume to highly branched cyclic dextrin is from about 2:1 to about 200:1; Preferably from about 4:1 to about 100:1, more preferably from about 6:1 to about 50:1, even more preferably from about 8:1 to about 30:1.

Hydrophobic perfume has a property of strongly binding to cyclic dextrin. The hydrophobicity of a perfume ingredient is related to the octanol/water partition coefficient P of that ingredient, which is the ratio of the equilibrium concentration of the perfume to octanol and water. As the perfume has a high partitioning coefficient P, it has more hydrophobicity. Conversely, as the perfume has a low partitioning coefficient P, it has more hydrophilicity. Since the partition coefficient of perfume is generally high, it can be conveniently expressed in the form of logP using the base 10 logarithm. Therefore, the other perfumes in the present invention have a logP value of about 3 or more, preferably about 3.1 or more, and most preferably about 3.2 or more.

In addition, each of the hydrophobic perfume compositions comprises at least about 5% to 80% by weight, preferably about 10% to 60% by weight, and more preferably about 15% to 40% by weight of the total fragrance composition.

More specifically, the highly branched cyclic dextrin according to the present invention is a fragrance that cyclodextrin could not contain: Galxolide, Eso-E super, Helvetolide, Cashmere. At least one or more fragrances from the group consisting of ranan (Cashmeran), cervolid (Cervolid), and Aurantiol (oranthiol) may also be included. These fragrances have excellent off-flavor masking ability, excellent preference for fragrance, have a large molecular weight and can more easily increase the persistence of fragrance as a hydrophobic fragrance.

Table 1 below shows the ability to bind to the cyclodextrin and the highly branched cyclic dextrin according to the present invention of some perfume fragrances. The highly branched cyclic dextrin according to the present invention has a more diverse and wider internal space than the cyclodextrin, so it can contain fragrances with a large molecular weight that cannot be entered into the cyclodextrin. Therefore, it is possible to apply more fragrance by using the highly branched cyclic dextrin according to the present invention, thereby broadening the fragrance spectrum of the present composition and increasing the persistence of reverberation.

Fragrance formulations for the present invention generally comprise at least 4, preferably 5, more preferably 6 and even more preferably 7 hydrophobic reverberant perfumes. In addition, the most widely used natural-derived fragrances consist of multiple constituents.

In addition, hydrophilic perfumes are characterized by being easily separated from highly branched cyclic dextrins in water-soluble compositions, and these hydrophilic perfumes are mainly composed of ingredients having a ClogP of about 3.5, preferably about 3.0 or less.

If the perfume ingredients are hydrophilic, they are soluble in water-soluble compositions and are not highly bound to cyclic dextrins. In order to maintain the function of the cyclic dextrin to reduce/remove foreign substances such as off-flavor, the hydrophilic fragrance has a weight ratio of the highly branched cyclic dextrin to about 90% by weight or less, preferably 50% by weight or less, more preferably It should be present at no more than 30% by weight, most preferably no more than 10% by weight. The ratio of cyclic dextrin to hydrophilic perfume should be at least about 8:1, preferably at least about 10:1, more preferably at least about 20:1, and most preferably at least about 70:1.

In addition, in the present composition, the fragrance may be present in an amount of 0.1 to 10.0% by weight, preferably 0.5 to 5.0% by weight, based on the total weight of the composition in order to perform its role, and when the above content is included, improvement can be maximized.

3) Solvent

In the present invention, the solvent means a carrier, preferably water is recommended, distilled water, water from which ions have been removed, or tap water can also be used. Water not only functions as a transporter of highly branched cyclic dextrin, but can also promote binding of highly branched cyclic dextrin with foreign substances such as off-odor molecules on the treated surface. In addition, it is known that the strength decreases when an aqueous solution is treated on a surface contaminated with odors generated by polar and low molecular weight organic amines, acids, mercaptans, and the like. It is thought that water used as a solvent in the present invention solubilizes polar, low molecular weight off-flavor molecules and reduces the vapor pressure, thereby lowering the strength of off-flavor.

The concentration of the solvent, ie, water, used in the composition of the present invention may vary depending on the use of the composition. The composition for manually or automatically sprayed sprays, the weight of water relative to the total weight of the composition is from about 30% to about 99.9% by weight, preferably from about 50% to about 99.9% by weight, more preferably from about 60% by weight. It is very high at about 95% by weight.

In addition, alcohol can be used as a solvent in the composition for removing the odor of the fabric, and the weight of the alcohol relative to the total weight of the composition is about 20% by weight or less, preferably about 10% or less, more preferably about 5% or less concentration is used.

The dilution of the aqueous solution can broaden the scope of application of the highly branched cyclic dextrin on the fabric, thereby maximizing the opportunity for the highly branched cyclic dextrin molecules to bind with the off-flavor molecules.

4) Surfactant

In the present invention, a surfactant may be further included in the composition of the present invention in order to appropriately reduce or remove foreign substances on the surface of an object or to allow the fragrance component to smell for a long time. For proper removal of off-flavor, the surfactant includes a stable surfactant capable of easily binding to the highly branched cyclic dextrin according to the present invention, and also to the off-flavor that is not easily encapsulated in the highly branched cyclic dextrin according to the present invention. It is important to form a polymer with a hydrophobic material and to generate a low surface tension to spread it more easily and uniformly on a hydrophobic surface such as a fabric.

Surfactants used in the present invention may include types commonly used in detergents, fabric softeners, shampoos, surface cleaners, cosmetics, body products, mouthwashes, body washes, shaving products, and skin moisturizers.

The use of a composition containing a stable surfactant in a highly branched cyclic dextrin will dry faster, depending on the type and characteristics of the surfactant applied, resulting in faster removal of off-flavors from the treated object. Among the ingredients of some compositions, fragrances that are not easily dissociated by inclusion with highly branched cyclic dextrin promote the formation of micelles or vesicles with highly branched cyclic dextrin and surfactants, and use from the treated surface by maintaining appropriate strength of fragrance Contributes to enhancing the long-lasting advantage of medium reverberation.

The binding force between the surfactant and the highly branched cyclic dextrin according to the present invention can be found by checking the change in interfacial tension (dyne/cm) depending on whether or not the highly branched cyclic dextrin is added to the aqueous surfactant solution. The aqueous surfactant solution contains a surfactant at a concentration of about 0.5%, about 0.1%, about 0.01%, or about 0.005%, and contains a surfactant having the same interfacial tension as the aqueous surfactant solution at a given concentration and contains about 1% by weight of the surfactant. If the increase in the interfacial tension of the aqueous solution further containing highly branched cyclic dextrin is about 10% or more, it means that a strong bond exists between the surfactant and the cyclic dextrin.

Preferably, the surfactant in the composition according to the present invention exhibits a change in interfacial tension. In the present invention, the surfactant weakly binds to cyclic dextrin (interfacial tension rises to less than about 5%) or preferably does not bind (interfacial tension is less than about 5%). rise to less than about 1%).

The concentration of a typical surfactant in the composition according to the present invention is between about 0.01% and about 2% by weight relative to the total weight of the composition, preferably between about 0.03% and about 0.6% by weight, more preferably about 0.05% by weight. between about 0.3% by weight. The concentration of surfactant in the concentrated surfactant composition is generally between about 0.1% and about 20% by weight, preferably between about 0.2% and about 15% by weight, more preferably between about 0.3% and about 10% by weight. between, but not limited thereto.

Effective surfactants in the present composition are selected as follows, but are not limited thereto. Examples include block polymer surfactants, siloxane surfactants, anionic surfactants, amphoteric surfactants, cationic surfactants, castor oil surfactants, sorbitan ester surfactants, polyethoxylated fatty alcohol surfactants, glycerol monovalent fatty acid ester surfactants, polyethylene glycol fatty acid ester surfactants, fluorocarbon surfactants, and mixtures thereof.

The block polymer surfactant includes block polymers of ethylene oxide and propylene oxide, and Pluronic ^® and Tetronic ^® may be used.

As the siloxane surfactant, polyalkylene oxide polysiloxane is suitable as an anionic surfactant, and it has a hydrophobic part dimethyl polysiloxane and a more hydrophilic polyalxylene chain. Examples of such surfactants include Silwet ^® . The number of ethyleneoxy (—C ₂ H ₄ O) units in the polyether chain (R ¹ ) must be sufficient to make the polyalkyleneoxide polysiloxane water-soluble. If the propyleneoxy group is present in the polyalkyleneoxy chain, it may be located randomly in the chain or as a block. In addition to the surface activity, polyalkylene oxide polysiloxane surfactants also have additional effects on the fabric, such as antistatic properties and flexibility.

Examples of the anionic surfactant include alkyldiphenyloxide disulfonate and alkyl ether sulfonate. In addition, anionic surfactants that can be used in detergents and shampoos include ammonium lauryl sulfate, ammonium laureth sulfate, triethylamine lauryl sulfate, triethylamine laureth sulfate, monohydric ethanolamine lauryl sulfate, and monohydric ethanolamine laurium.

Anionic surfactants for detergents suitable for the present composition are selected from ammonium laureth-3 sulphate, chlorinated laureth-3-sulphate, ammonium lauryl sulphate, lauryl chloride sulphate, and mixtures thereof. These anionic surfactants are not preferred because, when a cationic antibacterial active agent or a preservative is used, the binding to the cationic surfactant is reduced, thereby reducing the effect of the surfactant and the antibacterial agent.

Various amphoteric surfactants including the amphoteric surfactants can be used in the composition of the present invention. In particular, aliphatic secondary and tertiary amine derivatives are suitable, and their aliphatic radicals have a linear or branched structure, and one of them has a water-soluble functional group capable of ionization such as carboxy, sulfonate, sulfate, and phosphate.

Also, there are amino acid-derived surfactants and amino acid-derived surfactants as other surfactants, and the surfactant contains the basic chemical structure of amino acids, that is, the structure of natural amino acids. In general, surfactants are derived from N-methyl glycine such as glycine, sarcosine, glutamic acid, arginine, alanine, and phenylalanine.

The cationic surfactant generally includes quaternary nitrogen, and the fatty acid may include or bind to other functional groups such as amino groups in addition to carbon and hydrogen. Fatty acids with long chains containing about 12 or more carbon atoms may be saturated or unsaturated. in particular two long alkyl chains having from about 12 to about 22 carbons, preferably from about 16 to about 22 carbons and two short alkyl chains having from about 1 to about 3 carbons, preferably from about 1 to about 2 carbons. Cationic materials with a chain or one long alkyl chain and three short alkyl chains are suitable. Polyoxyethylene or poly wherein at least one substituent must also be hydroxyalkyl, preferably hydroxyethyl or hydroxypropyl, or polyoxyalkylene and having an overall degree of ethoxylation or propoxylation in the molecule from about 5 to about 20 Oxypropylene is suitable.

Common examples of sorbitan polyesters with long fatty acid chains are sorbitan tripalmitate, sorbitan trioleate, and sorbitan tallow fatty acid triesters. Another sorbitan ester surfactant is a class of sorbitan fatty acid esters with partially monovalent and trivalent esters. Another class of sorbitan ester surfactants are polyethoxylated sorbitan fatty acid esters.

The polyethoxylated fatty alcohol surfactants also include polyethoxylated fatty alcohol surfactants. Branched (polyethoxylated) fatty alcohols act as cyclic dextrin-compatible surfactants in this composition. Glycerol monovalent fatty acid esters As surfactants, glycerol monovalent fatty acid esters include glycerol monovalent stearate, oleate, palmitate, and laurylate. Polyethylene glycol fatty acid ester surfactants act as cyclic dextrin-compatible surfactants. Fluorocarbon surfactants have at least a hydrophobic moiety of an amphoteric material that is part of a carbon-based linear or cyclic functional group, a fluorine bonded to a carbon, and generally a hydrogen bonded to the carbon to form a hydrophilic moiety. Some common fluorocarbon surfactants include ionic surfactants such as fluorinated alkyl polyoxyalkylenes and fluorinated alkyl esters.

In the present invention, the water-soluble polymer may be further included in the composition of the present invention. Water-soluble polymers, such as water-soluble cationic polymers and water-soluble anionic polymers, may have an additional odor-removing effect, and are therefore more preferably included in the composition of the present invention. A representative example of the water-soluble cationic polymer is polyamine, and the water-soluble cationic polymer contains an amino group, an amido group, and a mixture thereof, and was used to remove a specific acid odor.

Water-soluble anionic polymers such as polyacrylic acid and their water-soluble salts are also used to remove certain amine odors.

In the composition of the present invention, other antibacterial agents, skin protectants, antistatic agents, moisturizers, and the like may be further included.

The composition for removing unwanted molecules according to the present invention applies a cyclic dextrin having a wider and various internal spaces, so that it is easy to remove unwanted molecules that could not be encapsulated in cyclodextrin, and more specifically, various odor sources. In addition, it could not be encapsulated in cyclodextrin, and a variety of hydrophobic and high molecular weight perfume substances could be encapsulated. Through such a composition, the fragrance material in the highly branched cyclic dextrin is replaced with an off-flavor, so that it emits a fragrance with excellent masking ability and preference for fragrance, while at the same time remarkably improved removal of foreign substances such as unwanted molecules such as off-flavor is possible

The following drawings attached to the present specification illustrate preferred embodiments of the present invention, and serve to further understand the technical spirit of the present invention together with the above-described content of the present invention, so the present invention is limited to the matters described in those drawings It should not be construed as being limited.
1 is a schematic diagram schematically showing the formation process of a highly branched cyclic dextrin according to the present invention.

Hereinafter, examples and the like will be described in detail to help the understanding of the present invention. However, the embodiments according to the present invention may be modified in various other forms, and the scope of the present invention should not be construed as being limited to the following examples. The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art.

<Example>

Since the composition according to the present invention consists of substances such as highly branched cyclic dextrin, fragrance and solvent, it is important to ensure that the function of highly branched cyclic dextrin is present in the composition during the production process of the present composition. In order to keep the functional highly branched cyclic dextrin within the composition, it must first be mixed with the highly branched cyclic dextrin with a surfactant. As a result, after molecular polymers such as micelles and vesicles are formed, substances such as fragrances are impregnated into the highly branched cyclic dextrin-surfactant molecular polymer, effectively separated from the interior space of the highly branched cyclic dextrin and functionally acting within the composition. composition can be maintained.

In the present invention, in order to remove the smell of fabrics, especially dry fabrics, the composition was prepared in the form of a spray and applied and evaluated. However, the efficacy of the present invention is not limited to the above formulation. It is preferable to use a composition in which a low concentration of highly branched cyclic dextrin is applied in order not to leave stains on the fabric in general usage, such as a spray-type formulation used for the purpose of removing odors from fabrics. should be invisible after drying.

The total weight of highly branched cyclic dextrin in the composition under normal use conditions is usually from about 0.01% to 5% by weight, preferably from about 0.1% to 4% by weight, more preferably from about 0.5% to 2% by weight. . In order to exert the function of highly branched cyclic dextrin in the composition, it is preferred to include at least about 0.001% to 0.1% by weight. Compositions with high concentrations can leave visible stains on fabrics as they dry, which can be a problem, especially on thin, colored synthetic fabrics.

3. Off-flavor strength evaluation

The evaluation of the odor removal effect on the compositions of Comparative Examples and Examples was carried out as follows.

1) For the fabric to be evaluated, a cotton towel cut to 30cm X 30cm is washed in a washing machine using an unscented detergent and dried with a dryer.

2) Apply about 80 microliters of odor prescription to each fabric on a dried cotton towel in an area of 5cm X 5cm, put it in a plastic bag, seal it, and leave it at room temperature overnight.

3) Trained evaluators evaluate the initial off-flavor strength of the fabric to which the off-flavor is applied, and score it according to the off-flavor rating scale below.

4) Then, apply the same amount of the prescriptions to be evaluated on the fabric and dry it for 30 seconds.

5) When the fabric dries, the evaluators score the off-flavor intensity of the fabric coated with the off-flavor according to the following off-flavor rating scale.

6) Record the initial score and the later score, and calculate the off-flavor reduction value with the difference between the scores.

A total of 8 evaluators were trained in advance to clearly recognize the standard off-flavor. The evaluation was conducted one by one in an independent evaluation booth equipped with forced ventilation, and to increase the accuracy of the evaluation, more than 3 evaluations at a time were limited.

Table 4 below is the evaluation criteria for off-flavor.

score Evaluation contents 0 points no odor 1 point There is a weak odor. 2 points Moderate odor. 3 points Has a slightly strong odor. 4 points Has a strong odor. 5 points Has a very strong odor.

In addition, for the reverberation evaluation by the cyclic dextrin, the intensity of the scent after 10 minutes and after 30 minutes was evaluated to evaluate the reverberation enhancing effect of the cyclic dextrin.

Table 5 below is a reverberation evaluation standard.

score Evaluation contents 0 points No scent at all. 1 point Has a weak odor. 2 points Medium odor. 3 points Has a slightly strong odor. 4 points Has a strong odor. 5 points Has a very strong odor.

4. Evaluation Results

Approximately 80 microliters of off-flavor prescription was applied to each fabric with an area of 5cm X 5cm on a cotton towel cut to 30cm X 30cm, sealed in a plastic bag, and left at room temperature overnight. The evaluation result was 4.2 points.

After applying Comparative Example 1 and Experimental Examples 1 to 7, after drying for 30 seconds, the difference between the evaluation result and the evaluation result of only Leechwiwon is shown in Table 6.

Evaluator No. comparative example Example 1 Example 2 Example 3 Example 4 Example 5 Example 6 Example 7 average 1.3 2.0 2.1 2.3 2.7 2.4 2.9 3.4

It was found that Examples 1 to 7 in which cyclic dextrin was used compared to Comparative Example 1 in which cyclodextrin was used as a odor removing agent had a better odor removal effect. Comparing Comparative Example 1 and Example 1, there is only a difference in the odor removing base, and in Examples 1 and 2, the content of the odor removing base is the same and there is a difference in the type. It can be seen that cyclic dextrin is better at removing odor than cyclodextrin when the amount of the odor removing agent is the same.

In addition, in the case of Examples 2 and 3, when Copolymer 958, a cyclic dextrin compatible polymer, was applied, it was confirmed that the odor removal effect by the cyclic dextrin was increased. When comparing Example 4 and Example 5, when the perfume content was changed to 0.10% and 0.06%, respectively, it was found that Example 4 having a high content was more excellent. In addition, when comparing Example 2 and Example 4 in which the application of Velvetex BK-35, which is an amphoteric surfactant, is different, the result of Example 4 to which the applied Velvetex BK-35 was applied was found to be better. By comparing Example 6 and Example 7, it can be seen comprehensively that the odor removal effect is increased when a cyclic dextrin compatible polymer and amphoteric surfactant that can provide a synergistic effect in removing odor of cyclic dextrin are added. there was.

In addition, the results of evaluating the reverberation intensity after 10 minutes and 30 minutes are shown in [Table 7]. Comparing Comparative Example 1 and Examples 1 to 7, it was found that the property of reverberation had a greater difference after 30 minutes than after 10 minutes. It can be determined that cyclic dextrin rather than cyclodextrin contains more perfume ingredients with a ClogP of 3.0 or more and a boiling point of 250 degrees or more and releases them over time.

In addition, as the content of cyclic dextrin increased, the difference between the reverberation after 10 minutes and the reverberation after 30 minutes was smaller, confirming this fact once again. By comparing Example 6 and Example 7, it was also confirmed that the reverberation enhancing effect of cyclic dextrin was further enhanced when a polymer, an amphoteric surfactant, that can increase the mutual adhesion between the fragrance and the fiber was added.
