Verdict
Suspected endocrine disruptor (flagged by France's MSCA in 2017); the SCCS concluded a potential risk to human health at concentrations exceeding the regulated thresholds. Skin sensitization possible at high levels. Synthetic phenolic antioxidant; highly effective at preventing rancidity in oil-based formulations; fat-soluble; often used in combination with BHA for synergistic antioxidant protection
US Note
Allowed - permitted as a cosmetic ingredient; also classified as GRAS for food use by the FDA (21 CFR 172.115); no specific cosmetic concentration cap in US regulation
