Problems solved by technology

[0005] Existing anti-acne cosmetics are directly adding active substances such as fruit acid, salicylic acid, phytosterols or allantoin without treatment, so that the active substances will directly act on the skin, which will cause the active substances to be damaged by the high concentration of the skin. The stimulating effect is strong, and it may even cause allergic reactions. On the other hand, the active substances of small molecules are released quickly, and cannot maintain effective concentration on the skin for a long time, which will affect the effect of acne removal

Embodiment 1

[0024] In the first step, 45.0 g of salicylic acid is completely dissolved in 22 g of deionized water, then 45.0 g of peach gum is added, and stirred evenly to obtain a main substance solution.

[0025] The second step is to add the main substance solution obtained in the first step into the uniform base liquid containing 10.0g triethanolamine and 44g deionized water, and uniformly disperse in the disperser for 3 hours, and then seal and stand at 25°C for 24 hours. Filtration 3 times gave a clear filtrate.

[0026] The third step is to vacuum freeze-dry the filtrate obtained in the second step. The drying temperature is -50°C, the vacuum degree is 0.1mbar, and the drying time is 18h; Instant product.

Embodiment 2

[0028] In the first step, 50.0 g of allantoin is completely dissolved in 28 g of deionized water, then 50.0 g of starch is added, and stirred evenly to obtain a main substance solution.

[0029] The second step is to add the main substance solution obtained in the first step into the base liquid containing 8.0g triethanolamine, 6.5g potassium hydroxide and 40g deionized water, and uniformly disperse in the disperser for 3h, and then at 28°C Sealed and stood for 36h, filtered 3 times to obtain a clear filtrate.

[0030] The third step is to vacuum freeze-dry the filtrate obtained in the second step. The drying temperature is -50°C, the vacuum degree is 0.05mbar, and the drying time is 18h; then the dried object is taken out and crushed, and the particle size of the powder is about 500 mesh. , the product is obtained.

Embodiment 3

[0032] In the first step, 35.0 g of allantoin and 25.0 g of phytosterols are completely dissolved in 25 g of deionized water, and then 46.0 g of pectin is added and stirred evenly to obtain a main substance solution.

[0033] The second step is to add the main substance solution obtained in the first step into the base liquid containing 12.0g sodium hydroxide and 50g deionized water, and uniformly disperse in the disperser for 4h, and then seal and stand at 30°C for 34h. Filtration 2 times gave a clear filtrate.

[0034] The third step is to vacuum freeze-dry the filtrate obtained in the second step. The drying temperature is -45°C, the vacuum degree is 0.08mbar, and the drying time is 19h; Instant product.

Abstract

The invention discloses a cosmetic additive with the permanent anti-acne function and a preparation method thereof. The method comprises: dissolving 40 to 60 mass portions of active substances into 20to 30 mass portions of deionized water, adding 30 to 50 mass portions of film-forming substances into the mixture, uniformly stirring the mixture, adding the mixture into a uniform base fluid containing 8 to 20 mass portions of auxiliary substances and 40 to 60 mass portions of deionized water, uniformly dispersing the obtained product in a viscolizer, hermetically standing the obtained product for 24 to 36 hours at the temperature of between 20 and 30 DEG C, and filtering the obtained product to obtain clear filtrate; and drying and crushing the clear filtrate to obtain powder with the granularity of between 60 and 1,000 meshes. The prepared powdery cosmetic additive has good water solubility and large solubility, is convenient to use, has good anti-acne efficacy in anti-acne water, anti-acne gel and anti-acne cream, and has good combination effect, large use range and long service life, wherein the service life of the powdery cosmetic additive is 1 to 2 times longer than that of theconventional additive with the anti-acne function.
