About

An ethoxylated surfactant phosphate ester with properties nearly identical to its C8 analog, functioning as an emulsifier with comparable mild irritation concerns.

Tri-C12-15 Pareth-6 Phosphate is structurally and functionally similar to the C8 homolog (Tri-C12-15 Pareth-8 Phosphate), differing only in the degree of ethoxylation (6 vs 8 moles). It is an ethoxylated alcohol phosphate ester used as an emulsifying surfactant. Not restricted in EU Annexes, though monitoring for 1,4-dioxane impurity is standard practice. The shorter ethoxylation chain may result in slightly higher irritation potential but similar overall safety.

Skin benefits

  • Emulsifying properties for stable emulsions
  • Surfactant function improves formulation aesthetics

Known concerns

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