Mea-laureth-6 Carboxylate is a cosmetic ingredient used in product formulations. Note: subject to regulatory restrictions in some markets. Exercise caution due to limited available safety data.

MEA-Laureth-6 Carboxylate is the monoethanolamine (MEA) salt of the carboxymethyl ether of laureth-6 (polyethylene glycol-6 lauryl ether). It is listed under EU Annex III, entry III/61 of Regulation (EC) No 1223/2009, which restricts certain alkyl ether carboxylate salts. MEA is a secondary amine and can participate in nitrosation reactions, forming N-nitrosomethylethanolamine (NMEA), which is considered a potential carcinogen. This risk is elevated in formulations containing nitrosating agents or at low pH. Formulators must avoid combinations with nitrosating agents and maintain pH above 7 when possible. At typical use concentrations in rinse-off products, the risk is manageable but requires careful formulation design.

Skin benefits

  • Mild anionic surfactant suitable for sensitive skin formulations
  • Provides good cleansing with reduced irritation vs alkyl sulfates

Known concerns

  • Secondary amine (MEA) can form nitrosamines in presence of nitrosating agents
  • EU Annex III/61 restriction requires formulation compliance
  • Eye and skin irritation possible at high concentrations
