### Sodium Ascorbyl Phosphate (CAS 66170-10-3): Stable Vitamin C Derivative for Advanced Skincare

Sodium Ascorbyl Phosphate, also known as **Sodium L-Ascorbyl-2-Phosphate** or **2-Phospho-L-Ascorbic Acid Trisodium Salt**, is a water-soluble and stable vitamin C derivative identified by **CAS No. 66170-10-3**. It is widely used as a cosmetic raw material in facial serums, brightening creams, lotions, masks, eye-care products, sunscreens, and multifunctional personal-care formulations. Compared with pure L-ascorbic acid, its phosphate structure can provide improved formulation stability and better resistance to oxidation under properly controlled conditions.

Sodium Ascorbyl Phosphate is valued for its antioxidant, skin-conditioning, and complexion-enhancing properties. It helps protect formulations and the skin’s appearance from oxidative stress caused by environmental factors and may support a brighter, smoother, and more even-looking complexion. It is commonly selected for products targeting dullness, visible dark spots, uneven tone, and early signs of environmental aging. Formulators may combine it with niacinamide, alpha-arbutin, tranexamic acid, hyaluronic acid, peptides, and sunscreen filters. Product developers should verify purity, active content, pH compatibility, concentration, packaging, storage, and local regulatory requirements.
