About
A viscosity-controlling agent and opacifier derived from DEA that is restricted in the EU due to nitrosamine formation concerns.
Stearamide DEA (diethanolamine) is listed under EU Cosmetic Regulation Annex III, entry III/60, which restricts the use of diethanolamine and its derivatives in cosmetic products. The restriction is specifically due to the potential for N-nitrosodiethanolamine (NDELA) formation — a known carcinogen — particularly when the product contains nitrate-based preservatives or is exposed to certain storage conditions. The compound is still permitted in cosmetic formulations but subject to strict purity criteria and concentration limits.
Skin benefits
- Acts as a viscosity controller in cosmetic formulations
- Functions as an opacifying agent in product formulations
Known concerns
- EU Annex III restricted (III/60) due to nitrosamine formation risk
- Potential for NDELA (N-nitrosodiethanolamine) formation during storage
