Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Read across to octadecyl methacrylate:
Octadecyl methacrylate: Density: 0.86 g/cm³ at 20 °C experimental result (Brandes E., Möller W (2003)
Octadecyl methacrylate: Density: 0.880 g/cm³ at 20°C handbook data (Lide DR (2005)
C16-C20 methacrylate (mainly octadecyl methacrylate): Density: 0.869 g/cm³ (experimental result, Evonik Oil Additives GmbH, 2008)
Key value for chemical safety assessment
- Relative density at 20C:
- 0.86
Additional information
Read across to structural analogue substance octadecyl methacrylate:
Octadecyl methacrylate: Density: 0.86 g/cm³ at 20 °C (experimental result, Brandes E., Möller W (2003)
supported by C16-C20 methacrylate (mainly octadecyl methacrylate): Density: 0.869 g/cm³ at 20°C (experimental result, Evonik Oil Additives GmbH, 2008) and octadecyl methacrylate density: 0.880 g/cm³ at 20°C (handbook data, Lide DR (2005).
Therefore the key value for this end point is the experimental determined value of relative density for octadecyl methacrylate of 0.86 g/cm³ at 20 °C (Brandes E, Möller W (2003)).
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.
