Abstract

The invention discloses a skin whitening composition, which is characterized by comprising the following components in portion by weight: 10 to 30 portions of undecylenoyl phenylalanine, 1 to 10 portions of glabridin and 20 to 80 portions of dibasic alcohol. The invention aims to overcome the defects existing in the prior art and provide the composition which is used for whitening cosmetics and can reduce the generation of melanin by inhibiting the generation of alpha-melanocyte stimulating hormone, tyrosinase, dopa mutase and DHICA oxidase. When the skin whitening composition is used for cosmetics, the cosmetics has obviously effects of removing freckles, whitening the skin and preventing and improving darkening, dark side, spots and freckles of the skin caused by sun exposure, ageing and the like.

Description

Technical field [0001] The invention relates to a skin whitening composition. Background technique [0002] With the overwhelming publicity of whitening cosmetics, the problem of exposure of whitening cosmetics has become more and more serious. Traditional whitening products often use hydrogen peroxide, ammonium chloride-based mercury and various phenol derivatives. These compounds can quickly disintegrate melanin tissue and achieve rapid whitening effects. However, due to its corrosiveness, cytotoxicity and allergies to the skin, it is extremely harmful, and many countries including our country have banned it. The existing whitening products mainly use the inhibition of the synthesis of melanin to achieve the whitening effect. However, on the one hand, traditional whitening products have a low penetration rate of active ingredients, and many consumers complain that the whitening products are not effective enough. For this reason, formula development engineers have to add a large...
