A kind of emulsifier composition capable of forming liquid crystal structure and its application

Abstract

The invention specifically discloses an emulsifier composition capable of forming a liquid crystal structure and its application. The weight percent of raw materials of the emulsifier composition is: 10-60% of hydrogenated lecithin, 5-40% of alkyl glycoside, and 5-50% of sucrose ester. The emulsified cosmetic prepared by using the emulsifier composition of the present invention can not only maintain a good liquid crystal structure at a temperature higher than 35° C., but also make the emulsified body non-sticky and have good skin feeling. Cosmetic emulsions containing liquid crystal structures, so-called liquid crystal cosmetics, have a refreshing and natural skin feel and good compatibility with active ingredients. The existence of liquid crystals in the emulsion can increase the storage stability of the emulsion, prolong the retention time of the hydration performance of the cosmetic and control the sustained release of the drug.

Description

technical field [0001] The invention relates to an emulsifier composition capable of forming a liquid crystal structure and its application, belonging to the field of cosmetics. Background technique [0002] As the outermost layer of the skin, the stratum corneum has the function of a natural barrier, which can prevent the evaporation of water, the loss of the skin's natural moisturizing factor, and the invasion of bacteria, viruses and external pollution. In this barrier function, oil plays an extremely important role. It forms a liquid crystal structure or oil layer in the stratum corneum to prevent the evaporation of water, which makes the stratum corneum have the effect of locking water. Therefore, if the layered structure is disordered and the keratinization process is abnormal, it will lead to the deterioration of the skin environment, such as: dry skin and so on. [0003] One way to improve skin moisture loss and ensure skin efficacy is to use skin care products tha...

AI Technical Summary

Problems solved by technology

These emulsifiers have different properties. For example, the emulsion prepared by hydrogenated lecithin emulsifier can maintain a good liquid crystal structure at a temperature higher than 35 ° C, but this emulsion is relatively sticky; sucrose esters and alkyl glycosides The emulsion prepared by emulsifier is relatively refreshing, but part of the crystalline structure will be destroyed when the temperature is higher than 35°C
