A kind of sunscreen composition and preparation method thereof

Abstract

The invention discloses a sunscreen composition and a preparation method thereof. The sunscreen composition comprises active ingredients in parts by weight: 1-50 parts of ultraviolet absorber; 1-20 parts of oil phase reagent; 50-95 parts of water phase reagent; 0.01-10 parts of emulsifier; 0.01-10 parts of rheology modifier; the preparation method is to heat the ultraviolet absorber, oil phase reagent and emulsifier to dissolve and mix, then add water phase reagent and rheology modifier, and mix well to obtain A sunscreen composition; the sunscreen composition is an oil-in-water type, does not add a film-forming agent, has excellent ultraviolet protection effect, excellent water resistance, and has a refreshing and non-sticky skin feeling.

Description

technical field [0001] The invention relates to a sunscreen composition and a preparation method thereof, belonging to the technical field of daily chemical products. Background technique [0002] In recent years, the impact of ultraviolet rays on the skin has been widely known, and consumers' awareness of sunscreen products has also continued to increase. Consumers not only need sunscreen products to exert higher UV protection capabilities, but also need to have a good sense of use. In cosmetics, the oil-in-water system is easier to obtain a refreshing skin feeling and has a better experience than the water-in-oil system. However, the water resistance of the oil-in-water system has always been the biggest defect of sunscreen products, although it can be improved by adding a film-forming agent. The water resistance of the oil-in-water system, but the sticky skin feeling of the film former will greatly affect the experience. [0003] In addition, organic sunscreens and inorg...

Problems solved by technology

In cosmetics, the oil-in-water system is easier to obtain a refreshing skin feeling and has a better experience than the water-in-oil system. However, the water resistance of the oil-in-water system has always been the biggest defect of sunscreen products, although it can be improved by adding a film-forming agent. The water resistance of the oil-in-water system, but the sticky skin feeling of the film former will greatly affect the experience

[0003] In addition, organic sunscreens and inorganic sunscreens such as titanium oxide and zinc oxide are widely used in sunscreen products. Although inorganic sunscreens can enhance the UV defense ability, a large number of inorganic sunscreens may cause whitening, roughness, or powdery makeup. situation, thus affecting the sense of experience

Most organic sunscreens are highly polar oils, which do not cause the above problems, but have a strong sticky feeling. If they are used in large quantities, they will damage the refreshing feeling of the oil-in-water system. In addition, the emulsification stability also tends to decrease.
