Abstract

The invention relates to a sunscreen bar capable of isolating ultraviolet A-wave and B-wave simultaneously and a preparation method thereof. The sunscreen bar comprises SOD (superoxide dismutase) oil mixed suspension, titanium dioxide, talcum powder, castor oil glyceride, carnauba wax, candelilla wax, cetyl alcohol, microcrystalline wax, beewax, octyl C12 alcohol and erucic acid oil-based ester. The specific preparation process comprises the following steps of: mixing castor oil glyceride, carnauba wax, candelilla wax, cetyl alcohol, microcrystalline wax, beewax, octyl C12 alcohol and erucic acid oil-based ester uniformly, then adding titanium dioxide and talcum powder, grinding, adding SOD oil mixed suspension, homogenizing and the injecting into a mould, so as to obtain the sunscreen bar. The sunscreen bar is capable of isolating ultraviolet A-wave and B-wave simultaneously, is free of sensitization source, has high safety and high cell viability, furthermore, the sunscreen bar is convenient to use, is portable, and can take supplementing and protective functions in time, so the sunscreen effect is better.

Description

technical field [0001] The invention relates to a sunscreen stick capable of simultaneously isolating ultraviolet A waves and B waves and a preparation method thereof, belonging to the technical field of cosmetics. Background technique [0002] UV absorbers are easy to penetrate into the skin, especially the degraded small molecules, which are easily absorbed by the skin and cause skin sensitization. Therefore, existing sunscreens use other sunscreen substances to partially replace chemical UV absorbers, such as the disclosed active substance containing snow lotus Sunscreen products, mainly composed of acrylic acid copolymer (Carbopol 940), glycerin, mixed alcohol, white mineral oil, benzophenone-3, isopropyl palmitate, monoglyceride, triacetamide, snow lotus extract, paraben Ethyl ester, vitamin E, essence, deionized water, etc., which reduce the contact sensitization and light contact sensitization of chemical UV absorbers alone, and supplemented with sunscreen made of les...
