Abstract

The invention relates to glycyrrhetinic acid liposome, comprising, by weight, 1-20% of lecithin, 0.01-0.5% of glycyrrhetinic acid, 1-10% of water-soluble grease, 1-15% of polyols, 0.1-2% of a surfactant, 0.01-0.2% of an inorganic salt, and the balance of water. The invention also provides a preparation method of the glycyrrhetinic acid liposome. The method includes: dissolving the lecithin and the glycyrrhetinic acid in a mixture of the polyols and the water-soluble grease to obtain an organic phase; evenly dispersing the surfactant and the inorganic salt, and dissolving them in water to obtain an aqueous phase; slowly adding the organic phase at constant speed into the aqueous phase to obtain glycyrrhetinic acid liposome suspension; stirring the glycyrrhetinic acid liposome suspension under ultrasonic to obtain a uniform system, and allowing the system to naturally cool to the room temperature to obtain the glycyrrhetinic acid liposome. The glycyrrhetinic acid liposome obtained by using the method has the stable system, long and slow-release action and mild to skin.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and relates to a glycyrrhetinic acid liposome and a preparation method thereof. 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] Glycyrrhetinic acid is the main active ingredient of the natural plant licorice. It is widely used in the field of medical cosmetics. ...
