What Is Dicetyl Phosphate?
Dicetyl phosphate is made from portions from cetyl alcohol and phosphoric acid to form an ingredient that functions as surfactant and emulsifier. Its primary role is to help control the viscosity of liquid cosmetic formulas as well as provide sensory improvements. It has a natural affinity for skin due to its phosphoric acid component’s relation to the phospholipids (a type of fatty acid) present in skin. Dicetyl phosphate is typically part of a blend with fatty alcohols and other phosphate ingredients made with cetyl alcohol. These blends have a nice synergy while that helps stabilize formulas while also being gentle on skin. Dicetyl phosphate is considered safe as used in cosmetics. Usage levels in leave-on products range from 0.2–4% and 0.038–1% in rinse-off products. Amounts up to 80% are considered non-irritating on skin.
This ingredient may be plant- or animal-derived or synthetic ( uses the plant-derived form which comes from coconut).
