About

Methylene Di-T-Butylcresol is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

METHYLENE DI-T-BUTYLCRESOL (also known as 2,2'-methylenebis(6-tert-butyl-p-cresol)) is a hindered phenolic antioxidant used in cosmetic and industrial formulations to prevent oxidation. While it is not currently listed in the EU Cosmetics Regulation Annexes as prohibited, it carries significant hazard classifications including H360F (suspected of damaging fertility), H361 (suspected of damaging the unborn child), and H413 (aquatic hazard). The German BfR and other regulatory bodies have flagged it as a substance of concern requiring further safety evaluation.
