Description of key information
A viscosity of 11.7 mm²/s at 20°C was assumed for the target substance Docosyl methacrylate based on a read-across approach.
Key value for chemical safety assessment
- Viscosity:
- 11.7 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The viscosity of the structural analogue substance 2-Propenoic acid, 2-methyl-, C16-20-alkyl ester was determined in a study according OECD TG 114. The kinematic viscosity of the test item was measured with a micro-Ubbelohde viscometer according to DIN 51 562 at 20°C and 40°C. Kinematic viscosity at 20°C was 11.7 mm²/s and the kinematic viscosity at 40°C was 6.60 mm²/s (Evonik RohMax Additives GmbH UNTER 08 -078). In two supporting guideline studies the viscosity of shorter-chained methacrylates (2-Propenoic acid, 2-methyl-, isodecyl ester; 8-methylnonyl methacrylate and -Propenoic acid, 2-methyl-, C12-16-alkyl ester) was determined to be 3.56 mm2/s and 6.24 mm2/s, respectively (Evonik RohMax Additives GmbH UNTER 08 -075, Evonik RohMax Additives GmbH UNTER 08 -081). All data are regarded as reliable. A viscosity of 11.7 mm2/s was assumed for the target substance Docosyl methacrylate.
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.
