Additional information
The data refer to measurements of substances of various single degrees of ethoxylation (EO = 2 and EO = 1). For a general ethoxylation degree of < 2.5 EO, a weight of evidence approach is applied.
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.
