Sodium Ascorbyl Phosphate (Sap)
Introduction
Sodium Ascorbyl Phosphate (SAP) is a stable, water-soluble derivative of Vitamin C widely used in cosmetic and personal care products. It offers the well-known benefits of Vitamin C—such as brightening, antioxidant protection, and skin clarity—while being significantly more stable and less irritating than pure ascorbic acid.
SAP gradually converts to active Vitamin C on the skin, making it ideal for long-term, daily-use formulations.
