Usage
ascorbic acid glucoside, also known as VC glucoside, with the scientific name O-A-D-pyran glucosyl-L-ascorbic acid (2-O-a-D-glucopyranosyl-L-ascorbic acid, abbreviated as AA-2G), is a derivative of VC with a relative molecular mass of 338.27. The melting point is 158.5-159.5℃. Due to the disadvantages of VC such as poor stability and easy oxidation, ascorbic acid glucoside, a substitute product of VC, has been derived. It can replace VC as an acidulant, reducing agent, antioxidant, bleaching agent and stabilizer, and is widely used in cosmetics, food and medicine fields.
After ascorbic acid glucoside is converted into vitamin C and enters the skin cells, it significantly reduces the formation of melanin by inhibiting the activity of tyrosinase. Inhibition of tyrosinase leads to a reduction of dopaquinone, which is an intermediate substance in the synthesis of melanin. Another additional benefit is that it simultaneously converts dopaquinone into levodopa, alleviating the already formed melanin and thereby reducing skin pigmentation. 2. Resist UV damage and inhibit the damage of ultraviolet radiation to cells. After ascorbic acid glucoside is converted into vitamin C, it can significantly reduce the free radicals produced by ultraviolet radiation in the skin, greatly reducing skin damage and playing a protective role for the skin in sunscreen products.
Ascorbic acid glucoside is one of the whitening additives approved by the Department of Health and is recognized as the most stable derivative of vitamin C. It is also the most commonly used whitening ingredient by major brands at present. For instance, L 'Oreal uses C-glycoside derivatives in synergy with other components to prevent or treat signs of aging in the body or facial skin. Ascorbic acid glucoside not only has a good whitening effect, but also has stable chemical properties and is non-irritating to the skin. It is widely used in cosmetics at home and abroad and has been recognized by the public. The following table lists the application situations of common vitamin C derivatives in cosmetics.
