Abstract

The invention provides lipidosome. The lipidosome is prepared from the following components in percentage by weight: 1-20 percent of lecithin, 1-15 percent of polyol, 0.1-2 percent of a surfactant, 0.01-0.2 percent of inorganic salt and the balance of water. The invention further provides a method for preparing the lipidosome. The method comprises the following steps: firstly, dissolving lecithin in polyol to obtain a uniform organic phase; secondly, uniformly dispersing and dissolving the surfactant and the inorganic salt in water to obtain a uniform aqueous-phase component; thirdly, slowly adding the organic phase into the aqueous phase at a uniform stirring velocity of 300-800rpm to obtain a uniform lipidosome suspension; and finally, performing ultrasonic treatment on the lipidosome suspension for 1-8 minutes with an ultrasonic power of 20-40 percent, stirring until the system is uniform, and naturally cooling the system to room temperature to obtain the lipidosome. The lipidosome prepared by the method has a stable system, can be used for simultaneously covering multiple effective ingredients, is mild to skin, and is a dispersion system with functionality and beautifying property.

Description

technical field [0001] The invention belongs to the technical field of cosmetics and relates to a preparation method of liposomes. Background technique [0002] Liposomes are hollow vesicles formed by phospholipids dispersed in water. They are widely used in cosmetics because of their unique phospholipid bilayers, which have a structure similar to cell membranes and have affinity with the skin. Liposomes provide remarkable properties for cosmetic formulations. They make the skin smooth, soft, elastic, and occlusive, and can create a thin film on the skin to prevent water loss from the skin. In addition, as a coating carrier, liposome can coat fat-soluble and water-soluble active ingredients in its phospholipid bilayer and hollow core, and act on the deep layer of the skin to play a slow-release effect. [0003] In the past ten years, the research on liposome in dermatology and cosmetics is booming. Liposome-containing cosmetics have incomparable advantages of traditional co...
