A kind of sunscreen cosmetic with water resistance and preparation method thereof

Abstract

The invention belongs to the technical field of cosmetics and provides a waterproof sunscreen cosmetic and a preparation method. In this method, isooctyl methoxycinnamate and 3-(4-methylbenzylidene) camphor are loaded on modified nanoporous zinc oxide to prepare composite sunscreen A, and 4-tert-butyl-4- Methoxydibenzoylmethane and diethylhexylbutyramide triazone are loaded on the modified nanoporous titanium dioxide to prepare composite sunscreen agent B, and then further made into waterproof sunscreen lotion. Compared with traditional methods, the sunscreen cosmetics prepared by the present invention can not only reduce the direct contact between organic sunscreens and skin, promote the uniform dispersion of inorganic sunscreens in the matrix, but also have good water resistance, can be used in underwater environments, and Provides comprehensive protection against long-wave and medium-wave UV rays.

technical field

[0001] The invention belongs to the technical field of cosmetics and provides a waterproof sunscreen cosmetic and a preparation method. Background technique

[0002] In recent years , the amount of ultraviolet radiation has been increasing along with the destruction of the ozone layer, and its impact on human beings has been recognized worldwide. At present, ultraviolet absorbing (shielding) agents with safe and efficient absorption of ultraviolet radiation have been widely used in cosmetics, hair care products, fabric treatment and detergents to protect the human body from excessive ultraviolet radiation. With the intensification of air pollution, the development and research of sunscreen will become the focus of researchers and consumers both now and in the future.

[0003] Sunscreen cosmetics mainly add sunscreen agents to play a role in sun protection. The mechanism of action of the ultraviolet absorber is to form a chelation ring between the base hydro...
