AMMONIUM TRIDECETH-6 PHOSPHATE

76

Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A phosphate-based emulsifying agent used to blend oil and water phases in cosmetic formulations, generally considered safe at normal use concentrations.

Ammonium Trideceth-6 Phosphate is the ammonium salt of a polyethoxylated tridecyl alcohol phosphate ester. It functions primarily as an emulsifying surfactant in cosmetic formulations, helping to create stable oil-in-water emulsions. The ethoxylation (6 EO units) moderates its irritancy compared to non-ethoxylated phosphate esters. The pubchem safety score of 78 is consistent with other phosphate surfactants used in skin care applications.

Skin benefits

  • Enables stable emulsion formulations
