About

An amphoteric surfactant derived from triethanolamine (TEA) and myristaminopropionic acid, restricted under EU Annex III due to nitrosamine formation concerns.

TEA-myristaminopropylate is classified under EU cosmetic regulation Annex III entry III/62, which restricts the use of TEA (triethanolamine) and certain TEA-derived surfactants in cosmetic products that can lead to nitrosamine formation. The restriction specifically addresses secondary amine reactions with nitrosating agents. Maximum concentration limits apply, and the ingredient must be formulated to avoid simultaneous presence of nitrosating agents to prevent NDMA and related nitrosamine formation.

Skin benefits

  • Foam-boosting amphoteric surfactant
  • Cleansing and mild detergent properties
  • Compatible with anionic and cationic ingredients

Known concerns

  • EU Annex III restricted (III/62) — TEA nitrosamine formation risk
  • Secondary amine precursor capable of NDMA formation
  • Requires formulation controls on nitrosamine-precursor combinations
  • Typical use in rinse-off products at controlled concentrations
