Safety Profile
EWG Skin Deep assesses POLYESTER-3 with a low hazard score across categories including cancer, allergies & immunotoxicity, and developmental & reproductive toxicity, acknowledging limited-to-fair data availability. Direct safety evaluations from CIR or SCCS for this specific cosmetic ingredient are not reported. Toxicity via oral, dermal, or inhalation routes remains undetermined, with no GHS classification found. While the FDA has approved related terephthalate polymers for medical devices and food packaging, this does not directly extend to POLYESTER-3 in cosmetic formulations.
