Description

A kind of instant soap particle composition and soap powder composition

technical field

The invention relates to an instant soap granule composition, a preparation method thereof and a soap powder composition, belonging to the technical field of daily chemical cleaning products, in particular to an instant soap granule composition with good fluidity, good solubility and simple preparation process , the composition is suitable for preparing soap powder in the form of adding later.

Background technique

Fatty acid soap is a very important surfactant. It is made by hydrolysis and saponification of natural animal and vegetable oils. People have used soap for thousands of years, and its safety has also been recognized by people. Soap is used in washing It is mainly used in the following two aspects:

1. As a foam control agent in detergents;

2. As a main surfactant used in washing powder, we call it soap powder. This kind of washing powder generally has a sodium fatty acid content ≥ 7.0, and the light industry standard QB/T 2387 is implemented. Laundry soap powder combines the advantages of laundry soap and laundry powder: natural environmental protection, mild and non-irritating, easy to rinse, and strong detergency. In recent years, it has become more and more favored by consumers, and its market share has been growing steadily.

In recent years, there have been a lot of reports on the research of fatty acid soaps in washing powders. For example, Chinese patent CN201210373480.7 discloses a kind of soft washing powders, including sodium alkylbenzene sulfonate, sodium tripolyphosphate, soap powder, sodium citrate, protease, Fluorescent whitening agent, essence, this soft washing powder has the functions of washing and softening. Chinese patent CN201210546771.1 discloses a fabric powder detergent, which is composed of copolymer of acrylic acid and maleic acid, polyaspartic acid, polyethylene glycol, soap powder, fluorescent whitening agent, sodium sulfate, lauryl Sodium benzenesulfonate, cocoyl monoethanolamine, nitrilotriacetic acid, starch oxidation product, the prepared detergent is in powder form, easy to carry, good decontamination effect, and has whitening and supple effect, especially suitable for fabric washing . In the above-mentioned report, the sodium fatty acid is added in the formula in the form of soap powder, and the soap powder mentioned here refers to the powdery granular raw material ground into laundry soap soap grains, and the proportion composition of the soap powder is not specified, usually this Soap powder has a high cost of raw materials due to high processing costs. In addition, the soap particles used for laundry soap usually contain more fatty acids with longer carbon chains, such as C16 fatty acid sodium and C18 sodium stearate, in order to ensure that the laundry soap has a certain hardness. , these ingredients tend to be very poorly soluble in water.

Some engineers have proposed to use fatty acid neutralization method to generate fatty acid soap in the process of producing washing powder. For example, Chinese patent CN 102604760 discloses a low-temperature instant soap powder, which is composed of fatty acid, alkali, auxiliary agent and surfactant. It has the advantage of low-temperature instant dissolving; Chinese patent CN201310028245.0 discloses a laundry soap powder slurry and its preparation method and an industrialized production process of laundry soap powder. The process adopts the method of direct neutralization of fatty acids to produce soap powder. The above-mentioned patent discloses that soap powder can be produced by neutralization of fatty acids, but this production process still has certain defects: first, the high viscosity of laundry powder slurry containing fatty acid sodium will lead to uneven dispersion of materials, and high viscosity is not conducive to spray drying The second is that sodium fatty acid is easily volatile and lost in the spray drying process, and also produces unpleasant odors to pollute the air environment; the third is that fatty acid soap sticks together with film-forming agent sodium natrium and zeolite to form water-insoluble particles.

Therefore, how to solve the poor operability and poor solubility of the laundry soap powder process is a technical problem that needs to be solved urgently.

The prior art of table 6 compares with the process of the technology of the present invention

It can be clearly seen from Table 6 that the process for preparing soap granules in the present invention is simpler than the prior art and can be completed in one step, so the production cost will be lower than the prior art.

Because the soap particles are added to the washing powder base powder to prepare soap powder by post-mixing, the soap particles need to have good fluidity and anti-caking properties, otherwise the process operability will be poor. Therefore, it is necessary to evaluate the fluidity and anti-caking properties of soap particles.

1. Comparison of fluidity of soap particles

testing method:

Fill the glass tube with a length of 50cm and an inner diameter of 3.5cm with soap particles, test the time required for all the detergent in the glass tube to flow out, and then calculate the flow rate of the detergent in ml/s;

Test method for anti-caking of washing powder:

Use a weight of 10 kg to press the sample into a cylinder, and then test the weight required to break the powder block, expressed in g, the larger the number, the easier the test sample is to agglomerate.

The soap granule fluidity and anti-caking data comparison prepared by table 7 prior art and the technology of the present invention

It can be seen from Table 7 that the fluidity and anti-caking property of the soap granules prepared by the technology of the present invention are better than those of the soap granules prepared in Comparative Example 1 of the prior art.

2. Solubility comparison of soap particles

Test method: Dissolve 2.5 grams of sample into 1L of distilled water, start stirring at a speed of 120 rpm, and observe the time it takes for the sample to dissolve to 90% of the maximum conductivity value.

Table 8 prior art compares with the soap granule solubility data prepared by the technology of the present invention

As can be seen from Table 8, the dissolution rate of the soap granules prepared by the technology of the present invention is better than that of the soap granules prepared in Comparative Example 1 of the prior art.

3, the comparison of the soap powder that embodiment 7 and embodiment 9 make

Fatty acid content loss comparison:

The technique of embodiment 7 is the production of fatty acid neutralization method in the pre-mixing stage, so there may be loss in the spray drying process. Now test and compare the fatty acid content of the soap powder of embodiment 7 and embodiment 9.

Table 9 embodiment 7 compares with the fatty acid content of embodiment 9 soap powder

As can be seen from Table 9, the fatty acid content will not be lost when the post-mixing process is adopted in Example 9, while the pre-mixing process of the fatty acid is used in Example 7, and the loss is more.

4. Solubility comparison

The dissolution appearance of Examples 7 and 9 is now evaluated.

Test method: Weigh 1 gram of sample and add it to 500ml of water, stir at 60 rpm for 30 seconds, and observe the appearance of the soap powder solution.

Table 10 embodiment 7 and embodiment 9 production process fatty acid consumption comparison

Example 7 is produced by the method of fatty acid neutralization in the pre-mixing stage. In the pre-mixing stage, the fatty acid is mixed with the intolerant substance zeolite in the formula. When the slurry is sprayed, the sodium hydroxide dries and loses water to form a film. The zeolite and Fatty acid soap sticks together, and the mixture of fatty acid soap, zeolite and sodium natrium is easy to float on the water surface, resulting in the feeling of poor dissolution of soap powder. In Example 9, the fatty acid soap is added in the form of after-mixing, and will not be bonded together with zeolite and natron, so the above phenomenon does not exist.

The above-mentioned embodiment is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited by the above-mentioned embodiment, and any other changes, modifications, substitutions, combinations, Simplifications should be equivalent replacement methods, and all are included in the protection scope of the present invention.
