Embodiment Construction

[0068] The present invention will be further described below in conjunction with specific embodiment:

[0069] Table 1: each component mass percent of embodiment 1-3

[0070]

[0071]

[0072] Embodiment 1-3 is tested, and the results are as shown in table 2:

[0073] Table 2:

[0074]

[0075] Among Examples 1-3, Example 3 is qualified, and at a moderate viscosity, no propellant is needed, the spray effect is good, and the material body is stable.

[0076] MONTANOV S can make fine titanium dioxide (titanium dioxide, average particle size 20×100nm, coated with simethicone) have excellent dispersibility. Observation under the microscope shows that the dispersion of titanium dioxide in the emulsion containing MONTANOV S is uniform and consistent, and remains constant for a long time (the shelf life of cosmetics is three years). In traditional emulsifier systems, it sticks together and forms lumps of various sizes in the emulsion.

[0077] The in vitro SPF value of E...

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

technical field [0001] The invention relates to a sunscreen spray and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] 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 help 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. [0003] 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 poor spreadability. A formula with a high content of emulsifier, low viscosity, and stable spray. Although it can reduce the heavy sk...
