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, which is composed of behenyl alcohol, cetyl alcohol, phytosterol and phytosterol ester, and the weight ratio of each raw material is: behenyl alcohol 1, cetyl alcohol 1 ~5, phytosterol 1~5, phytosterol ester 0.1~10. The invention simulates cholesterol and cholesterol esters in skin lipids, uses phytosterols and phytosterol esters as active ingredients, selects cetyl alcohol and behenyl alcohol to improve the solubility and melting point of the system, and obtains the plant through a better weight ratio The sterol composition solves the problem of poor mutual solubility of phytosterols and phytosterol esters in the prior art. At the same time, the obtained composition has good oil solubility and low melting point, and has strong operability in cosmetic formulations , conducive to the industrial application of phytosterols. The additive obtained by the invention is applied in cosmetics, can effectively exert the skin care properties of phytosterols and can improve the skin affinity of products.

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...
