Sodium Riboflavin Phosphate

Product Description

Sodium Riboflavin Phosphate is a highly stable, water-soluble derivative of Vitamin B2 (Riboflavin), commonly used in cosmetic formulations as a vitamin-based antioxidant ingredient. It is produced through controlled phosphorylation and purification processes to ensure consistent quality and formulation compatibility.

As a vitamin cofactor derivative, it is known for its role in supporting redox balance in cosmetic systems and helping protect formulations and skin from oxidative stress caused by environmental exposure.

Compared with riboflavin, its improved water solubility makes it suitable for modern aqueous cosmetic systems such as serums, toners, and emulsions targeting skin radiance and appearance improvement.
