Ascorbyl Phosphate
What is Ascorbyl Phosphate?
Ascorbyl Phosphate is a stable, water-soluble derivative of vitamin C (ascorbic acid) commonly used in skincare formulations to deliver antioxidant benefits without the instability issues of pure vitamin C. It is converted into ascorbic acid by enzymes in the skin, providing brightening, collagen-boosting, and anti-aging effects. This ingredient is gentler on sensitive skin compared to L-ascorbic acid and maintains efficacy in a wider pH range.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Skin protecting
Forms a barrier to protect skin from external irritants.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Antioxidant
Slows oxidation of oils, fragrances, and sensitive actives to improve shelf life and reduce rancidity or color change; sometimes also supports skin protection from oxidative stress.
