Sodium Ascorbyl Phosphate – A Powerful Antioxidant for Skincare (CAS: 66170-10-3)
Sodium Ascorbyl Phosphate is a stable, water-soluble derivative of vitamin C (ascorbic acid). It is primarily used in cosmetic formulations for its potent antioxidant properties, helping to protect the skin from environmental stressors. Unlike pure ascorbic acid, Sodium Ascorbyl Phosphate offers enhanced stability, making it a preferred choice for skincare formulations targeting anti-aging, brightening, and acne prevention.

Anti-Aging and Skin Protection Benefits
This vitamin C derivative stimulates collagen synthesis, contributing to wrinkle reduction and improved skin elasticity. By strengthening the dermis-epidermis connection, it enhances skin firmness and resilience, making it an ideal ingredient for anti-aging products. Additionally, its antioxidant properties help combat oxidative stress, inhibit lipid peroxidation, and reduce the formation of reactive oxygen species (ROS), thereby protecting against UV-induced and premature skin aging.

Brightening and Antibacterial Effects
Sodium Ascorbyl Phosphate is widely recognized for its brightening and depigmenting properties. It inhibits tyrosinase activity, effectively reducing hyperpigmentation and evening out skin tone. When used at concentrations up to 3%, it provides significant skin-lightening effects. Furthermore, it possesses antibacterial benefits, helping to control acne by inhibiting the growth of acne-causing bacteria and reducing sweat-related odor, making it a valuable addition to formulations for blemish-prone skin.

Formulation and Stability Considerations
Unlike pure ascorbic acid, Sodium Ascorbyl Phosphate remains stable in aqueous formulations with a pH above 7. This ensures its efficacy in various skincare products, including daily moisturizers (0.2–2%), sunscreens (0.2–1%), and acne treatments (0.2–5%). As a stable yet effective vitamin C derivative, it offers formulators a versatile and scientifically backed ingredient for advanced skincare solutions.
