Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
Diethanolamine isostearate cosmetic emulsifier and surfactant. The DEA class carries nitrosamine formation risk and faces tightening EU restrictions, limiting safety confidence to the orange tier.
Function
Skin benefits
- Functions as a non-ionic emulsifier and viscosity builder
- Isostearate chain offers oxidative stability versus unsaturated analogs
Known concerns
- Diethanolamine (DEA) derivatives can form nitrosamines if combined with nitrosating agents
- EU has restricted DEA and is moving away from DEA-amides in cosmetics
- CIR recommends DEA compounds only with strict nitrosation controls
- Potential skin and eye irritation at higher use levels
