About

Stearamidoethyl Diethylamine Phosphate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

This ingredient is an amidoamine phosphate ester — a diethylaminoethyl stearamide neutralized with phosphoric acid to form an amphoteric surfactant. It functions as an emulsifying agent and hair conditioning ingredient in cosmetic formulations. Not listed in EU Annex II or III restrictions. Amidoamine phosphates are generally well-tolerated but can occasionally cause mild skin or eye irritation in susceptible individuals, which is the primary factor limiting the safety score to the 70s range.

  • Emulsifying agent for oil-in-water formulations

Known concerns
