Stable weakly acidic whitening agent composition and preparation method thereof

Abstract

The invention discloses a stable weakly acidic whitening agent composition and a preparation method thereof. The stable weakly acidic whitening agent composition comprises the following raw materialsin parts by weight: 5-10 parts of 3-o-ethyl ascorbyl ether, 3-6 parts of nicotinamide, 2-5 parts of alpha-arbutin, 1-3 parts of butanediol, 1-3 parts of an emulsifier, 0.5-2.0 parts of jojoba seed oil, 0.5-2.0 parts of meadowfoam seed oil, 0.5-2.0 parts of tocopheryl acetate, 0.1-0.5 part of carbomer, 0.1-0.5 part of triethanolamine, 0.01-0.05 part of citric acid and the balance of water, whereinall the raw materials are 100 parts. Intervention and damping are performed on the whole stages of the initial stage, the middle stage and the final stage of melanin formation respectively, besides, the preparation method further performs micro-emulsification wrapping on the four whitening components to improve the stability of the four whitening components, and in addition, by adjusting the pH value, the absorptivity of the whitening agent, the compatibility of the skin and the stability of the whitening agent are improved. Therefore, the whitening agent which inhibits tyrosinase activation in the initial stage, inhibits oxidative antagonism in the middle-stage conversion process and prevents melanin transportation in the final stage, and is high in comprehensive skin absorptivity and extremely high in stability is obtained.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a stable weak acid whitening agent composition and a preparation method thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to facial skin care.

AI Technical Summary

Problems solved by technology

There are many kinds of whitening and freckle-removing products on the market, but the common problems are as follows: 1. The products are unstable and easy to be oxidized: the active ingredients that inhibit the formation of melanin are easily oxidized and difficult to store

2. The effect of use is not obvious: the ingredients with whitening and freckle removal are too single, and the whole process of melanin formation in the skin cannot be controlled globally, or the absorption rate of the product is too low

3. There may be hormones and other prohibited or exceeding the limit ingredients: In order to improve the whitening and freckle-removing effect of the product, some merchants add banned ingredients such as hydroquinone, which has a rapid whitening and freckle-removing effect
