Abstract

The invention provides a water-resistant liquid crystal cosmetic. Based on the total weight of the cosmetic, the cosmetic comprises the following raw materials in percentage by weight: 1.5-4% of a compound emulsifier which is compounded by docosyl alcohol, polyglycerol-10 pentastearate and sodium stearyl lactate and 1-6% of alkyl polyvinylpyrrolidone. The compound emulsifier comprises 30-60% of docosyl alcohol, 20-45% of polyglycerol-10 pentastearate and 10-30% of sodium stearyl lactate. The cosmetic provided by the invention can be the cosmetic for personal care such as foundation cream, skin cream and skin care emulsions. The cosmetic is a liquid crystal cosmetic which is good in fit with skins and fresh in skin touch, and the compound emulsifier and the alkyl polyvinylpyrrolidone in the liquid crystal cosmetic are compounded in use to have a synergistic effect for enhancing a water-resistant effect of the cosmetic. The liquid crystal water-resistant technology is also named as a PRW technology.

Description

technical field [0001] The present invention relates to a water-resistant liquid crystal cosmetic, in particular to a water-resistant cream-type or emulsion-type liquid crystal cosmetic for personal care, such as foundation cream, sunscreen lotion and the like. Background technique [0002] With the continuous deepening of the research on the relationship between skin science, cosmetic dosage form and function, and the basic research of cosmetic raw materials, liquid crystal cosmetics are gradually attracting people's attention. Liquid crystal cosmetics (liquid crystal cosmetics) show a microsphere network structure or a lamellar liquid crystal structure under a microscope. The liquid crystal structure is similar to the skin, so it has good affinity and adaptability to the skin, and has good permeability to the skin. Wettability, comfortable skin feeling, the liquid crystal structure can also increase the stability of the emulsified system, prolong the hydration performance ...
