About

A mild amino acid-based surfactant restricted in EU Annex III, likely due to concerns about nitrosamine formation or residual free oleic acid.

TEA-Oleoyl Sarcosinate is the triethanolamine salt of oleoyl sarcosinic acid, used as a mild surfactant and cleansing agent in cosmetic formulations. It is listed in EU Annex III (restricted substances) under entry III/62 in Regulation (EC) No 1223/2009, which restricts its conditions of use. TEA salts of fatty acids have been reviewed for potential nitrosamine formation, and the oleic acid moiety may contribute to mild skin irritation in sensitive individuals. The restriction in Annex III indicates specific concentration or use limitations apply.

Skin benefits

  • Mild amino acid-based surfactant for sensitive skin formulations
  • Good foaming properties with low irritancy potential

Known concerns

  • EU Annex III restricted (III/62) — specific use conditions apply
  • Potential for nitrosamine formation with TEA salts
  • May cause mild irritation in sensitized individuals
