About

An ethoxylated surfactant phosphate ester used in cosmetics as an emulsifier, with mild irritation potential at high concentrations but no EU-specific bans.

Tri-C12-15 Pareth-8 Phosphate is an ethoxylated alcohol phosphate ester functioning as a surfactant and emulsifying agent in cosmetic formulations. C12-15 alcohols are considered low-risk fatty alcohols, and phosphate esters of this type are not listed in EU Annex restrictions. Potential concerns include mild skin/eye irritation at high concentrations and residual 1,4-dioxane content from ethoxylation (which must be monitored per EU requirements).

Skin benefits

  • Emulsifying agent for stable formulations
  • Improves foaming characteristics

Known concerns

  • Mild skin/eye irritation possible at high concentrations
  • Potential 1,4-dioxane impurity from ethoxylation
  • Limited ecotoxicology data for aquatic environments
