Dicetyl Phosphate
What is Dicetyl Phosphate?
Dicetyl phosphate is a synthetic anionic compound formed by esterifying phosphoric acid with two cetyl alcohol molecules, resulting in a lipid-like structure with a hydrophilic phosphate head and hydrophobic cetyl tails. Commonly found in cleansing formulations, lotions, and creams, it acts primarily in oil-in-water emulsions. Its surfactant properties reduce surface tension between oil and water, enabling dirt and oil removal during cleansing while forming micelles that encapsulate impurities. As an emulsifier, it creates a protective film at the oil-water interface, preventing phase separation and ensuring product stability and smooth texture over time. This dual functionality makes it suitable for daily use in shampoos, body washes, and moisturizers, contributing to consistent performance without compromising formulation integrity.
