一种液晶型防晒乳液的制备与性能研究
Preparation and performance study of a liquid crystal sunscreen lotion
摘要
Abstract
Based on liquid crystal emulsification technology,a combination of macromolecular organic sunscreens and physical sunscreens was used to study and develop the formula of sunscreen lotion.The performance of the sunscreen lotion formula was analyzed by observing the liquid crystal structure of the lotion,investigating the stability of the formula,and using human sun protection index test and chemical skin absorption in vitro test.The study showed that in this sunscreen formula system,the combination of alkyl glycoside emulsifiers and polyglycerol emulsifiers is easier to form a liquid crystal structure than lecithin emulsifiers.The physical sunscreen zinc oxide is not conducive to the formation of the liquid crystal structure of the formula and the stability of the formula.The liquid crystal emulsification system helps to improve the sun protection index of the formula system to a certain extent.The liquid crystal structure has a certain sustained release effect on the active ingredients in the sunscreen cosmetic formula.关键词
