Safety score · 0–100

Fine

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

An ethoxylated lauryl ether carboxylic acid that cleans by lowering surface tension — gentler than SLS-style sulfates. Trace 1,4-dioxane from ethoxylation is the main quality concern, manageable by purification.
