Safety score · 0–100

Avoid

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

A DEA-neutralised ethoxylated alkyl sulfate. The DEA counter-ion is a secondary amine that can form NDELA, a probable carcinogen — the well-documented reason DEA surfactants are being phased out across the EU.

Function

SURFACTANT - CLEANSING

Skin benefits
