Abstract

The invention relates to a liquid crystal type emulsifying compound, a preparation method and an application thereof. The liquid crystal type emulsifying compound comprises the following components byweight: 0.01-5% of liquid crystal type emulgator, preferably 0.1-3%; 0.01-5% of suspension stabilizer, preferably 0.3-4%; 0.1-5% of water-in-oil emulgator, preferably 0.5-4%; 0.1-5% of higher aliphatic alcohol, preferably 0.5-3%; 30-80% of water, preferably 50-75%. The liquid crystal type emulsifying compound disclosed by the invention is gentle and no-stimulation, is high in stability, has the functions of deeply moistening and effectively preserving moisture and is capable of forming a liquid crystal protective barrier on skin surface, protecting skin from being injured by external environment and effectively relieving the skin problem under environmental pressure. The liquid crystal type emulsifying compound disclosed by the invention also has a certain spreadability and glossiness andis capable of achieving a long-acting moistening effect and keeping skin long-lasting moisturized and glossy.

Description

technical field [0001] The invention relates to a liquid crystal emulsified composition, a preparation method and application thereof, and belongs to the field of cosmetics. Background technique [0002] With the rapid development of cosmetic technology and the improvement of consumers' awareness of multiple preferences for products, various emulsification systems have appeared on the market, including common oil-in-water emulsification systems and water-in-oil emulsification systems, as well as phase transition emulsification systems. system and microemulsion package emulsification system, etc. There are more and more types of emulsified products, and their functions are gradually diversified. However, most of the emulsified products on the market are based on the oil-in-water system or the water-in-oil system, and there are also multiple emulsification systems such as water-in-oil-in-water or oil-in-oil. Formula stability is greatly affected by temperature changes; formu...
