Description

Sodium L-Ascorbyl-2-Phosphate is a stable, water-soluble derivative of Vitamin C (ascorbic acid). This compound is valued for its enhanced stability against oxidation, heat, and light compared to pure ascorbic acid, making it ideal for formulations requiring long-term shelf life. It is primarily utilized as a powerful antioxidant and skin-brightening agent in the cosmetic, personal care, and nutraceutical industries.

Application

• Cosmetic & Skincare Formulations: As a stable source of Vitamin C in serums, creams, and lotions for antioxidant protection, collagen synthesis, and skin brightening.
• Anti-Aging Products: Key ingredient in products targeting fine lines, wrinkles, and improving skin elasticity.
• Personal Care Products: Used in shampoos, conditioners, and body washes for its antioxidant and stabilizing properties.
• Nutraceuticals & Dietary Supplements: Incorporated into stable supplement formulations for its Vitamin C activity.
• Aquaculture & Animal Feed: Serves as a stable Vitamin C source in feed for fish and livestock to support health and growth.
• Pharmaceutical Preparations: Used in topical and some oral formulations where a non-acidic, stable form of ascorbate is required.
