Caution

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

An emulsifier built on diethanolamine. Because DEA can form cancer-linked nitrosamines, this ingredient is banned in EU cosmetics and discouraged elsewhere, so it scores poorly on safety.

Skin benefits

  • Provides stable, uniform product texture

Known concerns

  • Contains diethanolamine (DEA), which can form carcinogenic nitrosamines
  • DEA-containing cosmetic ingredients are prohibited in the EU
  • Listed under California Proposition 65 as a cancer-causing agent
