Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Density data was not available for any of the streams within this Category. However as the category consists of mainly C4 hydrocarbons, data were read across from hydrocarbon C4 substances (CAS numbers 107-01-7: 0.588 g/cm3(cis) and 0.616 g/cm3(trans), 115-11-7: 0.59 g/cm3, 106-98-9: 0.588 g/cm3, 25167-67-3: 0.56 g/cm3to 0.62 g/cm3). All information came from a peer reviewed handbook (CRC, 2008) and all measurements are at 20°C. The density range for this Category was determined as 0.555 - 0.62 g/cm3.
The mean of the density values for the category is 0.594 g/cm3at 20°C and this has been used to complete the 'key value for chemical safety assessment'.

Additional information
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.
