How we reached this

Polyethylene glycol ester used as thickener + emulsifier. Functional + safe per FDA OTC monograph. Concern: PEG family carries 1,4-dioxane contamination risk from the ethoxylation process; manufacturers can vacuum-strip to reduce. EWG cosmetic database flags PEG class for that contamination history.
