Abstract

The invention discloses a skin whitening and moisture preserving cosmetic based on hydroxyl radicals. A mixed solution T is prepared from tetra-n-butyl titanate, absolute ethyl alcohol, glacial aceticacid, lauryl sodium sulfate, sodium polyacrylate, N,N-dimethylethanolamine, tetrasodium pyrophosphate, concentrated sulfuric acid, sodium metasilicate, PtCl4 and PbCl2; a mixed solution U is preparedby adding lauryl sodium sulfate, glycerinum and Twain-80 into the mixed solution T; an emulsion V is prepared from stearin, caprylic / capric triglyceride and isopropyl palmitate; the mixed solution isdropwise added into the emulsion V in a shaking table at the temperature of 75 DEG C, and then stirring is carried out at the condition of 100 r / min for 50 min so as to obtain an emulsion which is the skin whitening and moisture preserving cosmetic based on hydroxyl radicals. The cosmetic has the beneficial effects that the cosmetic obtained with the method can shield ultraviolet rays, and has the functions of skin whitening, moisture preserving, sun screening and the like.

Description

technical field [0001] The invention belongs to the technical field of cosmetic preparation, and in particular relates to a whitening and moisturizing cosmetic based on hydroxyl radicals and a preparation process. Background technique [0002] Cosmetics are light chemical products closely related to people. They are applied to human skin, hair, nails and lips by smearing, spraying or other methods to achieve the purpose of cleaning, eliminating bad smell, skin care, beauty and modification. With the improvement of living standards, people pay more and more attention to self-modification and have higher and higher requirements for cosmetics. Basic formulas with only simple skin care ingredients cannot meet the needs of current consumers. Cosmetics will gradually become more scientific, natural and Effective direction development. Therefore, cosmetics with ordinary and simple structure no longer have a competitive advantage, and cosmetics with more active ingredients in the f...
