Conclusion on classification
According to reliable short term studies conducted on fish, invertebrates and algae 6,6'-di-tert-butyl-4,4'-diethyl-2,2'-methylenediphenol is not acutely toxic to aquatic organisms. 6,6'-di-tert-butyl-4,4'-diethyl-2,2'-methylenediphenol is not rapidly degradable, it has an experimentally determined BCF > 500 and it is poorly soluble in water. Based on these properties the substance fulfills the criteria to be classifed as Aquatic Chronic Category 4 according to the CLP and GHS criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
