About

A diethanolamine-based emulsifier and surfactant for cosmetic formulations, subject to EU restriction due to potential nitrosamine formation.

DEA-PEG-4 laurate is a diethanolamine salt of PEG-4 laurate, used as an emulsifying and skin conditioning agent. It is listed in EU CosIng with restriction II/411 under the Cosmetics Regulation, requiring that it does not contain more than 0.5% DEA and that it is not used with nitrosating systems. This restriction addresses the theoretical risk of nitrosamine formation from secondary amines like DEA reacting with nitrosating agents.

Skin benefits

  • Effective emulsifying agent for oil-in-water formulations
  • Provides skin conditioning properties

Known concerns

  • EU restriction II/411 — DEA content must be below 0.5%
  • Theoretical nitrosamine formation risk — avoid combination with nitrosating agents
  • DEA can be a skin sensitizer at elevated concentrations
