About

A higher-ethoxylate coconut-fatty-amine surfactant. Slightly milder than PEG-10 cocamine but carries the same PEG-amine cautions on impurities.

PEG-15 cocamine is the 15-mole-ethoxylate coconut-alkyl tertiary amine (CAS 61791-14-8 series), used as a surfactant, emulsifier, and oil solubiliser. Higher ethoxylation generally yields milder skin profiles than PEG-5/10 variants. As with all ethoxylated ingredients, residual ethylene oxide and 1,4-dioxane (IARC 2B) must be monitored. Being a tertiary amine, it is a potential nitrosamine precursor if combined with nitrosating agents. The CIR assessment of related PEG-cocamines supports cosmetic use with formulation safeguards; PEG-15 specifically has a thinner data record.

Skin benefits

  • Mild cationic surfactant and emulsifier
  • Antistatic in hair care
  • Improves oil solubilisation

Known concerns

  • Ethoxylated tertiary amine — possible nitrosamine formation with nitrosating agents
  • Residual 1,4-dioxane and ethylene oxide monitoring required
  • PEG-amines skew more irritating than PEG-alcohols
  • Limited CIR-specific assessment for PEG-15 variant
