Additional information
For the evaluation of this endpoint data from two handbooks (CRC Handbook and Merck Index) and one data base (Gestis database) were used as a weight of evidence.
According to ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a, specific handbook data for physic-chemical properties are considered to be a reliable data source. Useful reference books and data compilations containing peer reviewed physico-chemical data include the Merck Index and the CRC Handbook of Chemistry and Physics.
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.
