Abstract

The invention discloses a phenethyl resorcinol nano-structure lipid carrier, a preparation method and application of the phenethyl resorcinol nano-structure lipid carrier in cosmetics. The nanostructure lipid carrier comprises the following components in percentage by mass: 0.1%-2% of mixed lipid, 0.1%-2% of a surfactant and the balance of a carrier, the content of the mixed emulsifier is 1%-4%; and the balance of water. The nano-structure lipid carrier effectively improves the stability and encapsulation efficiency of active substances, has a slow release effect, is easy to prepare on a large scale, and has a better application prospect in the field of cosmetics.

Description

technical field

[0001] The invention relates to a nano-lipid carrier, in particular to a phenylethyl resorcinol nano-structured lipid carrier, a preparation method and an application in cosmetics. Background technique

[0002] As a functional raw material of cosmetics, whitening agent has received great attention. Its development and application research have been deepened continuously, and high-efficiency raw materials on the market have been continuously updated. As one of the current mainstream whitening agents, phenylethyl resorcinol (PR) mainly reduces the content of melanin by inhibiting the activity of tyrosinase. It is quicker than kojic acid and more in line with the needs of consumers. However, its poor water solubility and instability when exposed to light limit its application in whitening products, so it is necessary to wrap it with an appropriate delivery system to improve its photostability and solubility; and the natural barrier of the skin is to a large exte...
