Description
Ascorbyl glucoside, also known as AA 2G or ascorbic acid 2-glucoside, is a stable glycoside form of vitamin C produced by enzymatic bonding of glucose to ascorbic acid. It carries CAS number 129499-78-1 and EC number 603-337-7, and is supplied as a powder for industrial formulation use.
In cosmetic formulations, ascorbyl glucoside functions as a skin conditioner and antioxidant by releasing free ascorbic acid enzymatically upon skin contact, enabling controlled vitamin C activity without the instability associated with pure ascorbate. It also acts as a humectant in topical products and serves as an antioxidant additive in food and pharmaceutical preparations to retard oxidative degradation.
Ascorbyl glucoside is available in cosmetic and food-grade specifications and is subject to REACH registration requirements within the EU. It is classified under HS code 2938909090. Procurement quantities and packaging formats vary by supplier; buyers should confirm grade suitability against applicable regional cosmetic or food safety regulations.
