Potassium Ascorbyl Tocopheryl Phosphate
What is Potassium Ascorbyl Tocopheryl Phosphate?
Potassium Ascorbyl Tocopheryl Phosphate is a synthetic compound derived from L-ascorbic acid (vitamin C) and alpha-tocopherol (vitamin E), linked through a phosphate group and neutralized with potassium. This creates a water-soluble, stable molecule resistant to oxidation and degradation compared to pure vitamins. In cosmetics, it belongs to the antioxidant and skin conditioning agent categories. It functions by donating electrons to neutralize free radicals, preventing lipid peroxidation in formulations and on skin surfaces. Its dual structure provides synergistic protection, enhancing stability of other actives like oils and fragrances while supporting product shelf life. Typically incorporated into serums, creams, and lotions at low levels for broad-spectrum oxidative defense without altering pH significantly.
