Problems solved by technology

Moreover, the films formed by most water-based or oil-based film-forming agents are usually relatively flat, unable to perform self-cleaning functions, fail to achieve anti-pollution effects, and are also weak in air and moisture permeability, and are prone to closed acne after use. Happening
[0005] However, polymethylsilsesquioxane and silica silylate are usually used in color cosmetics to regulate skin feel and viscosity, but polymethylsilsesquioxane and silica silylate have not been found to be Applications in the preparation of film-forming agents

Abstract

The invention discloses a cosmetic film-forming composition with lotus leaf effect, and the film-forming composition comprises acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer, and also comprises polymethylsilsesquioxane and / or silica silylate. According to the present invention, the film formed on the skin surface is uniform and has no crack, and characteristics of good water resistance, good oil resistance, good friction resistance, good pollution resistance, and good gas permeation and moisture permeation performance are provided.

Description

technical field [0001] The invention relates to a film-forming composition, in particular to a film-forming composition for cosmetics with lotus leaf effect. Background technique [0002] In recent years, with the continuous development of the economy, the expansion of cities, and the increasingly serious environmental problems, the skin, as the first line of defense of the human body, is exposed to the polluted environment for a long time, bears huge pressure, and is prone to a series of damage, aging, allergies, etc. The problem, therefore, is the need to ward off external pollution by applying cosmetics. At present, the anti-pollution methods of cosmetics mainly include film-forming isolation, adsorption, anti-oxidation, cleaning and removal, etc. Among them, the use of film-forming technology to isolate pollution is currently the most widely used anti-pollution method, and adding film-forming agents to cosmetics can improve The water resistance and friction resistance o...
