How we scored it
Diester of phosphoric acid (mineral, natural) with 2x cetyl alcohol (C16 fatty alcohol, oleochemical, natural). All fragments natural: 547/547 Da = 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Dicetyl Phosphate is made by esterifying phosphoric acid, a mineral-derived acid, with cetyl (C16) fatty alcohol typically sourced from coconut or palm oil. Some cetyl alcohol supply is petrochemical (Ziegler/oxo process), which a supplier certificate should confirm.
In plain English
An emulsifier that helps mix oil and water in lotions and creams. It is made from a fatty alcohol derived from coconut or palm oil combined with mineral phosphate.
Structure
