Problems solved by technology

However, using phytosterols and phytosterol esters at the same time also has a great technical problem. Phytosterols and phytosterol esters are not miscible, and when added to cosmetics, the solubility is not good, and the efficacy is not good. Restrictions, for this reason, those skilled in the art generally choose to add one when using, and will not add both at the same time

Abstract

The invention discloses a phytosterol composition for cosmetics. The phytosterol composition for cosmetics consists of the following raw materials in parts by weight: 1 part of behenyl alcohol, 1-5 parts of cetyl alcohol, 1-5 parts of phytosterol and 0.1-10 parts of phytosteryl ester. According to the phytosterol composition, cholesterol and cholesteryl ester in skin lipid are simulated, phytosterol and phytosteryl ester are used as active ingredients, cetyl alcohol and behenyl alcohol are carefully selected to improve the solubility and melting point of a system, and the phytosterol composition is obtained through a better weight part ratio. The problem that in the prior art, phytosterol and phytosteryl ester are added at the same time and are poor in intersolubility is solved, and meanwhile the obtained composition is good in oil solubility, low in melting point, high in operability in a cosmetic formula and beneficial to industrial application of phytosterol. The obtained additive is applied to cosmetics, the skin care characteristic of phytosterol can be effectively exerted, and the skin friendliness of the product can be improved.

Description

technical field [0001] The invention relates to a phytosterol composition, in particular to a cosmetic phytosterol composition which can be used in cosmetic production, has stable performance and good efficacy, and its preparation method and application. Background technique [0002] Phytosterols used in cosmetics can maintain skin surface moisture, promote skin metabolism, inhibit skin inflammation, and prevent sun erythema and skin aging. However, it is difficult to add phytosterols to cosmetics, because free phytosterols are extremely difficult to dissolve in water and have low oil solubility. The solubility in ethanol is 1.17g / 100mL (23°C), which is difficult to apply in cosmetic formulations, especially Oil-based cosmetics are more difficult to apply, and their low solubility also directly affects their efficacy in cosmetics. The melting point of phytosterols is relatively high, which is 130-180°C, and the maximum preparation temperature in cosmetic production is gener...
