CLEAR OILY SOLUTION OF PHOSPHORYLCHOLINE POLYMER, COSMETIC RAW MATERIAL STOCK SOLUTION, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/166926
Kind Code:
A1
Abstract:
The present invention provides a clear oily solution of a phosphorylcholine polymer, a cosmetic raw material stock solution, and a preparation method therefor. Specifically, the present invention provides a clear oily solution of a phosphorylcholine polymer containing the phosphorylcholine polymer, an emulsifier, and grease, and a preparation method therefor. Under the action of a hydrophobic monomer and a hydrophilic monomer in the phosphorylcholine polymer structure, the phosphorylcholine polymer is dissolved in a specific emulsifier and dispersed in an oily solution to form a clear solution; the application of the phosphorylcholine polymer in oil-based, water-in-oil, and oil-in-water formulations of cosmetics is increased, and the film-forming property thereof is used, thereby reducing irritations and improving the stability and the moisturizing effect. The present invention further provides corresponding cosmetic raw material stock solutions such as a licoflavone oily stock solution, a ceramide oily stock solution, and a dipotassium glycyrrhizinate oily stock solution.
