Problems solved by technology

However, there are disadvantages such as uneven dispersion, poor sun protection effect and waterproof effect.
[0007] To sum up, in the current commonly used sunscreen cosmetics, the technical method of directly adding sunscreens, inorganic sunscreens have the problem of easy aggregation, poor dispersion, and difficulty in blending into cosmetics, while some chemically synthesized sunscreens are easy to oxidize due to poor photostability Deterioration can cause skin allergies, and traditional sunscreen products are generally poor in waterproofness, and their practicability needs to be strengthened. Therefore, it is of great significance to develop a safe and efficient sunscreen cosmetic with waterproofness

Abstract

The invention belongs to the technical field of cosmetics, and provides a waterproof sunscreen cosmetic and a preparation method. The method comprises the steps that iso-octyl 4-methoxycinnamate and 3-(4'-methylbenzylidene)camphor are loaded on modified nano porous zinc oxide to prepare a composite sunscreen agent A; 4-tert-butyl-4-methoxydibenzoylmethane and diethylhexyl butamido triazone are loaded on modified nano porous titanium dioxide to prepare a composite sunscreen agent B; a waterproof sunscreen lotion is further prepared. Compared with a traditional method, the prepared sunscreen cosmetic can prevent the skin from being in direct contact with the organic sunscreen agents, promote the uniform dispersion of inorganic sunscreen agents in a medium, have good waterproofness, be used in the underwater environment and achieve the comprehensive protection against long-wave ultraviolet rays and medium-wave ultraviolet rays.

Description

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 the 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 hydrog...
