Description

Whitening and skin-brightening composition and preparation method thereof

Technical Field

The invention relates to the field of daily chemical articles, and particularly provides a whitening and skin-brightening composition and a preparation method thereof.

Background

Whitening and brightening the skin is one of the most extensive demands for skin care of Asian women. With the progress of science and technology and the depth of research, more and more raw materials having whitening efficacy are applied to cosmetics. For example, most of the existing whitening cosmetics mainly take kojic acid and derivatives thereof, hydroquinone, arbutin, licoflavone, tretinoin, tartaric acid and azelaic acid as main components of the whitening agent, but the two are excessively used to cause damage to skin. Kojic acid is generally extracted from filamentous fungi such as Penicillium, Aspergillus, etc., and is a cell with toxicity, and there is a risk of carcinogenesis when overused. Excessive use of hydroquinone can cause cytotoxic reaction; and hydroquinone is very frightened, and the product is easy to discolor and deteriorate, so a large amount of ultraviolet absorbent or light stabilizer is often needed to be matched, and the product is a great burden for skin. In addition, the permeability of active substances of arbutin, licoflavone, tretinoin, tartaric acid and azelaic acid is not ideal, so that the whitening products have poor effect.

In addition, most consumers seeking whitening effect often put higher requirements on the time period of whitening effect and the requirements on sun protection, moisture retention and water replenishing, but the existing commonly used whitening skin care products cannot play a role in rapid whitening. Therefore, the development of the skin care product with the functions of whitening, sun screening and moisturizing has wide market prospect.
