Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A non-ionic surfactant (ethoxylated branched lauryl alcohol). Functional but, like other ethoxylates, can carry trace 1,4-dioxane unless purified.
Isolaureth-6 is a polyethylene-glycol ether of branched lauryl alcohol (with about six ethylene-oxide units). It acts as a non-ionic surfactant, emulsifier, and solubilizer in cleansers, lotions, and color cosmetics. The ethoxylation process can produce trace 1,4-dioxane (a probable human carcinogen) as a contaminant unless manufacturers strip it. CIR considers laureth/isolaureth-class surfactants safe when 1,4-dioxane is controlled below 10 ppm. Skin tolerance is generally good; rinse-off products may cause mild defatting at higher use levels.
