Aminopropyl Ascorbyl Phosphate

Product Description

Aminopropyl Ascorbyl Phosphate (AAP) is a stable water-soluble Vitamin C derivative widely used in cosmetic and personal care formulations requiring antioxidant support and aqueous compatibility.

Compared with traditional Ascorbic Acid, AAP offers improved formulation stability and better compatibility in water-based systems while maintaining a gentle sensory profile suitable for modern skincare applications.

Commonly incorporated into serums, lotions, gels, masks, and lightweight emulsions, Aminopropyl Ascorbyl Phosphate supports cosmetic formulations focused on antioxidant performance, refreshed skin appearance, and stable water-phase delivery systems.
