Abstract

The invention discloses sunscreen aerosol and a preparing method thereof. The sunscreen aerosol is composed of sunscreen components, polydimethylsiloxane, emulsifying components and other additives like propylene glycol and magnesium aluminum silicate, wherein the sunscreen components include homosalate, ethylhexyl methoxycinnamate, ethylhexyl salicylate, 4-methylbenzyl camphor, titanium dioxide, and the emulsifying components include sodium acrylate / acrolyl-dimethyl sodium taurine, isohexadecane, polysorbate-80, coconut-based glucoside, oleyl alcohol, glyceryl stearate, and PEG-100 stearate. The sunscreen aerosol is low in viscosity, the product system is stable, the SPF value is constant and enduring, the breathability is good after the sunscreen aerosol is sprayed, the formed film is compact, excellent water resistance is achieved, and thus a long sunscreen effect is achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to a sunscreen spray and a preparation method thereof, belonging to the technical field of cosmetics. [0003] 【Background technique】 [0004] With the improvement of people's awareness of sun protection, more and more people pay attention to sun protection products, and the market for sun protection products is also growing. For sunscreen, the reaction and synergy between raw materials are helpful to develop safe and effective sunscreen products that meet the ever-changing industry, excellent stability, mildness, unique skin feel, high SPF and full-band sunscreen , good waterproof performance, easy to use, etc., are crucial. [0005] Sunscreen In order to achieve high SPF and full-band sunscreen effects, it is common practice to add high doses of sunscreen agents, but this will result in poor material stability or spreadability. A formula with a high content of emulsifier, low viscosity, and stable spray. Although it ca...
