Additional information
Toluene has a Henry's Law Constant of 485 Pa.m3/mol. The value has been calculated based on the physico-chemical properties of the substance and the equation set out in the Guidance R16 (ECHA 2012). The result is supported by data from the CRC Handbook (Lide 2008). No information on the methods used is available but this information is taken from a reliable peer reviewed handbook and is considered reliable and suitable for use for this endpoint.
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.
