Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxooctadecyl)-.omega.-hydroxy- (100 mol EO average molar ratio)

PEG-100 STEARATE is listed in the European Commission CosIng inventory under the functional category Surfactant - Cleansing, with CAS number 9004-99-3. In the free INCIDB sample it appears on 8 product labels, reaching position 7 on bolero Beverly hills moisturizing body cream. Fulton (1989) grades it 0 on the 0–5 comedogenicity scale; that grade is transcribed as-is and is the only rating source used. INCIDB's rule-derived heuristic flags it as a possible Malassezia (fungal-acne) trigger. That is a rule, not a measurement — treat it as a filter rather than a finding.
