β-谷甾醇/硬脂酸凝胶的制备及其在防晒化妆品中的应用
Preparation of β-sitosterol/stearic acid gel and its application in sunscreen cosmetics
摘要
Abstract
β-sitosterol and stearic acid can form stable gels.They have broad application prospects in the field of cosmetics.In this paper,a series of gels were prepared by adjusting the polarity of the oil,the content of β-sitosterol,and stearic acid.Polarizing microscopy,Fourier transform infrared spectroscopy,and rheometer were used to analyze the structure and stability of the gels.The results show that the gel network is formed based on crystallization and self-assembly between β-sitosterol and stearic acid molecules.The gels with better performance are introduced to the sunscreen lotion to explore the application advantages of gels in sunscreen products.The rheometer,UV/Vis spectrophotometer,and high-performance liquid chromatograph were used to analyze the stability,sun protection and transdermal properties of the emulsion.The results show that the introduction of the gel improves the stability and enhances the sun protection of the emulsion significantly.Furthermore,the existence of gel reduces the transdermal amount of sunscreen and thus improves the safety of the product.This study provides not only basic information for the effective application of β-sitosterol/stearic acid gel,but also a foundation for the development of high-performance sunscreen cosmetics.关键词
