Problems solved by technology

[0007] There are also sunscreen cosmetics related to anti-ultraviolet in the prior art, but the anti-ultraviolet components of the cosmetics in the prior art are relatively single, resulting in poor anti-ultraviolet effect. With the improvement of consumer requirements, it is necessary to develop a kind of anti-ultraviolet ability Strong, non-toxic and harmless sunscreen cosmetics will have great economic value

Abstract

The invention discloses a sunscreen essence emulsion capable of effectively resisting ultraviolet injury and a preparation method thereof. The preparation method comprises the following steps: 1. preparation of an oil phase: adding an emulsifier 1, an emulsifier 2, cetyl lactate, C12-C15 alkyl lactate, myristyl myristate, an ultraviolet absorbent 1, an ultraviolet absorbent 2, an ultraviolet absorbent 3 and propanediol into a reaction kettle A to obtain the oil phase; 2. preparation of a water phase: stirring modified nano titanium dioxide, deionized water and xanthan gum to obtain the water phase; 3. grinding of small materials to obtain dispersed small materials; 4. mixing and emulsification: filtering the oil phase and the water phase, pumping into a vacuum emulsifying machine, adding the dispersed small materials, heating to 70-85 DEG C, stirring at the rate of 50-100r / min for 10-20 minutes, and adding a preservative and essence to obtain the sunscreen essence emulsion; and 5. aging and filling to obtain the sunscreen essence emulsion capable of effectively resisting ultraviolet injury.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a sunscreen essence effectively resisting ultraviolet damage and a preparation method thereof. Background technique [0002] As we all know, there are various wavelengths of light in sunlight. Among them, the wavelength range of ultraviolet light is 100-400nm. According to the wavelength, ultraviolet light can be subdivided into short-wave ultraviolet, medium-wave ultraviolet and long-wave ultraviolet. -290nm, 290-320nm, and 320-400nm, among them, the ultraviolet light with the highest radiation intensity reaching the surface through the atmosphere is long-wave ultraviolet light, which also causes greater damage to the skin. The skin surface is irradiated by ultraviolet light for a long time, which will lead to dark skin. Sunscreen cosmetics that are anti-ultraviolet on the skin surface are very important. [0003] At present, the main sunscreen cosmetics are sunscreen, which ...
