ISOPROPYL MYRISTATE

Not on the EU Annex III list Rule-flagged fungal-acne trigger

ISOPROPYL MYRISTATE is listed in the European Commission CosIng inventory under the functional categories Binding, Skin Conditioning - Emollient, Fragrance, Perfuming, with CAS number 110-27-0 and EC number 203-751-4. In the free INCIDB sample it appears on 4 product labels, reaching position 5 on Crème réparatrice pieds très secs. Fulton (1989) grades it 5 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.
