Ascorbyl Glucoside (CAS NO: 129499-78-1) is a water-soluble vitamin C derivative synthesized from ascorbic acid and glucose. Renowned in cosmetics for its stable, non-irritating nature, it acts as a gradual-release form of vitamin C, offering antioxidant, brightening, and anti-aging benefits. As a white crystalline powder, it overcomes the instability of pure vitamin C, making it suitable for various formulations, from serums to sunscreens.
