What it is
C20-22 Alkyl Phosphate is a phosphate ester of long-chain fatty alcohols that acts as an emulsifier and is commonly paired with C20-22 Alkyl Alcohol in a complete emulsifying system. It helps create stable, skin-friendly oil-in-water emulsions with a light, non-greasy feel. In sunscreens it supports an even, stable distribution of UV filters and other ingredients throughout the product.
