Ascorbyl Glucoside,Vitamin C Glucoside(CAS 129499-78-1)
Ascorbyl Glucoside (AA2G) is a high-stability glycosylated modified vitamin C derivative, a core star raw material for high-end whitening and antioxidant skincare. Different from ordinary L-ascorbic acid (raw VC) which is extremely unstable, easy to oxidize, yellow and decompose, AA2G adopts advanced glucose glycoside grafting modification technology.
It completely solves the defects of traditional VC such as poor stability, photosensitivity, easy discoloration and skin irritation. It can stably exist in various cosmetic formulas without failure and yellowing. After penetrating into the skin, it can be efficiently converted into active vitamin C, exerting powerful antioxidant activity, scavenging excess free radicals in the skin, blocking melanin synthesis pathway, fading pigmentation and dull yellow complexion.
This product has mild properties, no photosensitivity, can be used day and night, does not irritate sensitive skin, and has excellent anti-oxidation, brightening and anti-aging effects. With ultra-high purity, stable batch performance and wide formula adaptability, it is the preferred safe whitening and antioxidant raw material for international high-end skincare brands.
