Embodiment 1

[0035] A whitening and blemish-reducing additive for cosmetics, calculated by weight percentage, comprising the following components:

[0036] Butanediol 25%, Calamine 55%, Vitamin C Ethyl Ether 3%, Arbutin 12% and Diglucosyl Gallic Acid 5%.

[0037] Preparation:

[0038] 1) Weighing alcohol, calamine, vitamin C ethyl ether, arbutin and diglucosyl gallic acid according to the proportioning;

[0039] 2) dissolving arbutin, vitamin C ethyl ether and diglucosyl gallic acid in some alcohol to obtain solution A;

[0040]3) dissolving calamine in the remaining alcohol and stirring to disperse to obtain solution B;

[0041] 4) Mix solution A and solution B evenly

Embodiment 2

[0043] A whitening and blemish-reducing additive for cosmetics, calculated by weight percentage, comprising the following components:

[0044] Butanediol 10%, Calamine 50%, Vitamin C Ethyl Ether 15%, Arbutin 15% and Diglucosyl Gallic Acid 10%.

[0045] The preparation method is basically the same as in Example 1, except for the content of each component.

Abstract

The invention provides a skin-whitening and spot-fading additive used for cosmetics and a preparation method and application of the skin-whitening and spot-fading additive. The skin-whitening and spot-fading additive used for cosmetics comprises the following components in percentages by weight: 10% to 35% of alcohol, 14% to 65% of calamine, 3% to 15% of vitamin C ethylether, 1% to 15% of arbutinand 1% to 10% of diglucosyl gallic acid. The preparation method comprises the following steps: (1) dissolving arbutin, vitamin C ethylether and diglucosyl gallic acid into a part of alcohol to obtaina solution A; (2) dissolving calamine into remaining alcohol for stirring dispersion to obtain a solution B; and (3) uniformly mixing the solution A with the solution B to obtain the additive. The activity of tyrosinase in skin can be effectively inhibited, and the formation of melanin is blocked, so that the additive has the effects of spot fading and skin whitening and is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a whitening and spot-lightening additive for cosmetics, a preparation method and application thereof. Background technique [0002] Human skin color is largely determined by the production, migration and distribution of melanin. Melanin is the most important pigment in the skin, it determines our skin color. At the same time, melanin is also the natural defense system of human skin, which can resist the damage of ultraviolet rays to the skin. When melanin is uniformly and excessively deposited in the epidermis of the skin, the skin color will become dark, and the local excessive deposition of melanin is the fundamental principle of freckles and chloasma. The reaction steps of melanin formation: (1) Copper-containing tyrosinase catalyzes the oxidation of tyrosine to generate dopa in the presence of oxygen free radicals. This step of reaction proceeds very slowly at...
