Safety score · 0–100

Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A amphoteric surfactant derived from lauraminopropionic acid and diethanolamine (DEA), subject to EU restriction III/411 due to nitrosamine formation potential.

DEA-lauraminopropylate is classified under EU cosmetic regulation entry III/411, which restricts the use of diethanolamine and its derivatives in cosmetic products that may lead to N-nitrosodimethylamine (NDMA) formation. The restriction applies to substances that can release DEA under in-use conditions, as secondary amines can react with nitrosating agents to form carcinogenic nitrosamines. Concentration limits and purity specifications apply.

Skin benefits

  • Cleansing and foaming surfactant properties
  • Used in rinse-off formulations at controlled concentrations

Known concerns

  • EU Annex III restricted (III/411) — nitrosamine formation risk
  • Secondary amine capable of forming carcinogenic NDMA
  • Requires strict purity controls to minimize nitrosamine precursors
  • Must not be used in combination with nitrosating agents
