What it does

Sodium cetearyl sulfate is the sulfate of cetearyl alcohol. Unlike SLS it is mostly used at low levels to help oil and water stay mixed in creams and lotions, often with cetearyl alcohol as a ready-made emulsifying wax. CosIng lists it as cleansing, foaming and surfactant.

Our sulfate-free check counts every alkyl sulfate, so a product listing it gets a no even when it is there as an emulsifier. The cetearyl part can be plant or animal derived, which leaves the vegan answer at not sure.
