Abstract:
Disclosed is a skin whitening, firming and moisturizing face cream and a preparation method therefor. The method comprises dispersing carbomer and arbutin in glycerol to prepare a water phase, and taking stearic acid monoglyceride and stearic acid as an oil phase in advance to obtain a cream A; adding deionized water to hydrolyzed oat protein, pearl hydrolysate, and an acrylic (acrylate)/C10-30 alkanol acrylate cross-linked polymer, to act as a water phase; and taking dicaprate, olive oil and polyethylene glycol cetyl alcohol ester as an oil phase to form a cream B. Due to the fact that stability is relatively poor when alpha-arbutin is used in face cream for whitening, same is wrapped with the acid carbomer in the oil phase, and the weak acid environment of carbomer enables arbutin to be present in the weak acid environment, such that the arbutin is stable in the face cream. In the cream B, the hydrolyzed oat protein and the pearl hydrolysate form water-in-oil, the hydrolyzed oat protein has the effect of instant tightening, the feeling of instantaneous tightening on skin is generated, and the feeling of moisturizing, film-forming and making skin smooth can be achieved for the skin.
