Sodium Riboflavin Phosphate
What is Sodium Riboflavin Phosphate?
Sodium Riboflavin Phosphate is the disodium salt of riboflavin 5'-phosphate, a phosphorylated and stabilized form of riboflavin, also known as vitamin B2. This water-soluble ingredient originates from the essential B vitamin, often produced synthetically for stability in formulations. In cosmetics, it belongs to the skin conditioning category, commonly found in moisturizers, serums, and creams. It functions by helping to retain moisture in the skin's outer layer, supporting the natural barrier function, and contributing to a smoother texture. Its hydrophilic nature allows it to attract and hold water, aiding in maintaining hydration balance without greasiness. This makes it suitable for various product types, particularly those aimed at daily skin maintenance.
