Description

Composition for nourishing scalp and caring hair, and preparation method and application thereof

Technical Field

The application relates to the technical field of daily necessities, in particular to a composition for nourishing scalp and caring hair, and a preparation method and application thereof.

Background

Washing and caring integrated hair care shampoo and other hair and scalp care products become important daily necessities. Along with the social development and the improvement of the living standard of people, the demand of people on health is continuously improved, and more people realize that products with natural sources, organic and non-irritant have irreplaceable effects of artificially synthesizing chemical substances on the health of hair.

There are several types of hair care compositions available today: 1. chemically synthesized raw materials such as conditioning agents such as cations, silicone oil, synthetic grease and the like; 2. a pure traditional Chinese medicine composition; 3. adding Chinese medicinal composition into plant extract (liquid); 4. plant extract (liquid) is added with vitamin. However, most of these hair care compositions only protect the hair and neglect the scalp care. Even some of the prior hair care compositions contain chemically synthesized materials and are therefore more or less irritating to the scalp.

Therefore, there is a need to develop a product that has both functions of nourishing the scalp and caring hair, and is non-irritating to the scalp.

Disclosure of Invention

The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

The application provides a scalp and hair care composition which is safe, mild and non-irritant, and has functions of nourishing the scalp and caring the hair, and a preparation method and application thereof.

Specifically, the present application provides a composition for nourishing the scalp and caring for the hair, comprising the following raw materials: plant amino acids, ginkgo leaf extract, olive extract, eclipta prostrata extract, soapberry extract, bergamot fruit extract and water.

The plant amino acid obtained by hydrolyzing the plant protein belongs to vegetarian nutrition, has the function of nourishing scalp and caring hair, and enables the hair to be more natural and healthy.

Ginkgo leaf has effects of promoting blood circulation, stimulating hair growth, and promoting new hair generation.

When the olive acts on the scalp, the olive can effectively nourish hair follicles, repair scalp cells, improve the scalp environment, stimulate the hair growth and make the scalp alive.

The snakehead intestine is also called eclipta, and the Ming dynasty Li Shizhen is written in Ben Cao gang mu: ecliptae herba has effects of blackening hair and beard and tonifying kidney yin. Eclipta is an annual herb plant belonging to the family of Compositae, and is a good medicine for blackening and nourishing hair from old times.

The soapberry has the effects of cleaning scalp and improving the quality of the scalp, so that the skin is fine and smooth and has elasticity; it also has antioxidant, antibacterial, antiinflammatory, and free radical scavenging effects, and can be added into hair product for preventing alopecia and promoting hair growth.

In the present application, the weight of each extract is calculated as the pure substance of the extract excluding the extraction solvent.

In some embodiments, the plant amino acids may be 8 to 16% by weight, the ginkgo biloba extract may be 4 to 6% by weight, the olive extract may be 3 to 7% by weight, the eclipta prostrata extract may be 4 to 5% by weight, the soapberry extract may be 2.5 to 5% by weight, the bergamot fruit extract may be 5 to 7.5% by weight, and the balance water, based on 100% by weight of the composition.

In some embodiments, the plant amino acids may be 15% by weight, the ginkgo biloba extract may be 5% by weight, the olive extract may be 3.5% by weight, the eclipta prostrata extract may be 4.5% by weight, the soapberry extract may be 3% by weight, the bergamot fruit extract may be 6% by weight, and the balance water, based on 100% by weight of the composition.

In some embodiments, the plant amino acid may be an amino acid of one or more combinations of betaine, histidine, lysine, trimethylglycine, arginine, glycine, glutamic acid, aspartic acid.

In the present application, ginkgo biloba extract, olive extract, eclipta prostrate extract, soapberry extract, bergamot fruit extract may be prepared by methods known in the art or may be obtained by purchase (e.g., from Shanghai Lisheng Biochemical Co., Ltd.).

In some embodiments, each extract may be prepared by a solvent extraction method, wherein the solvent may be selected from any one or more of water, ethanol, ethyl acetate, propylene glycol, methyl propylene glycol, and butylene glycol. The content of total ginkgetin in the folium Ginkgo extract is 24.0% and the solid content is 20% based on the dried product. The oleuropein content in the olive extract may be 20.0%. The total flavone content in the eclipta prostrata extract can be 5%, and the triterpenoid saponin content can be 20%. The content of sapindoside in the fructus Sapindi Mukouossi extract can be 20%. The total content of vitamins in fructus Citri Grandis extract is 10%.

The present application also provides a method for preparing a composition for nourishing scalp and caring hair, comprising the steps of:

weighing 5-25 wt% of plant amino acid, 1.5-7.5 wt% of ginkgo leaf extract, 0.5-7.5 wt% of olive extract, 2.5-5 wt% of eclipta prostrata extract, 0.5-7.5 wt% of soapberry extract and 1.5-10 wt% of bergamot fruit extract;

adding the plant amino acid into a proper amount of water, and stirring until the plant amino acid is completely dissolved;

adding the ginkgo biloba extract, the olive extract, the eclipta prostrata extract, the soapberry extract and the bergamot fruit extract, and adding water to 100% by weight to obtain the composition for nourishing scalp and caring hair.

The present application also provides the use of the composition for nourishing the scalp and caring for the hair as described above, prepared by the method as described above, in a rinsing or leave-on hair product.

In some embodiments, the rinsing or leave-on hair product may be a shampoo, a cream shampoo, a conditioner, a hair mask, a hair spray, a hair rinse, or a hair conditioner, which is prepared by adding an auxiliary material to an active ingredient of the hair product.

The composition for nourishing and caring the scalp has double effects on the hair and the scalp, and is beneficial to the health of the hair and the scalp. The composition can clean scalp, increase scalp water content, moisten scalp, and eliminate inflammation, thereby nourishing scalp and keeping scalp healthy. The composition also has a repairing effect, and can repair hair damaged by hair scale structure such as ironing and dyeing, on one hand, the toughness of the hair is effectively improved, and the hair has better tensile strength; on the other hand, the hair scales are more orderly, so that the brightness and the flexibility of the hair are improved, and the hair conditioner has the effects of strengthening and nourishing the hair.

Further, the composition of the application combines various plant extracts and plant amino acids, so as to obtain a synergistic effect. The single plant extract (solution) or plant amino acid has very weak effects of caring hair and nourishing scalp. When the components in the composition are reasonably combined in the specific proportion defined by the application, the synergistic effect among the components can be enhanced, so that the hair and scalp improvement effect is remarkable, and the effects of nourishing and caring the scalp can be achieved.

In addition, the components of the composition are natural in origin, and have the characteristics of being natural, safe, mild, non-irritant and the like, so that the composition has a wide application range, and can be used for various rinsing or residing hair products, such as: hair products such as shampoo, shampoo cream, hair conditioner, hair mask, hair spray, scalp care solution, hair spray, hair moistening essential oil, etc. Particularly preferred product forms are leave-on hair products, such as: leave-on hair conditioner, scalp care solution, hair spray, hair tonic essential oil, etc.
