N-(Trichloromethylthio)phthalimide (Folpet - ISO) is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.
Folpet (ISO) is a phthalimide-derived fungicide used in agriculture since the 1950s. Its hazard profile encompasses multiple serious concerns: H317 indicates skin sensitisation potential, H351 classifies it as a suspected carcinogen, H361 indicates reproductive toxicity, H372 indicates specific target organ toxicity with repeated exposure, and H330 indicates acute inhalation toxicity. Its trichloromethylthio group can dissociate to yield phthalimide and carbon disulfide. The compound is authorised as a pesticide but has no place in cosmetic formulations; the EU CosIng database does not list it as an authorised cosmetic ingredient.
