Key value for chemical safety assessment
- Viscosity:
- 44.03 mm²/s (static)
- at the temperature of:
- 20 °C
Additional information
The test was performed as a well-documented study according the relevant standard method ASTM D445/04, classified as Klimisch 1. The kinematic viscosity of the test item was determined reproducibly in two trials to be 44.03 mm²/s at 20 °C and 19.61 mm²/s at 40 °C. The determination of the viscosity instead of the particle size distribution is reasonable because the 75 % aqueous solution is the marketed form, the substance is not isolated and is additionally hygroscopic. Hence, the results are reliable and can be used for further risk assessment.
The outcome of the study is reliable without restrictions, consistent within the expected range and determined by a relevant method. Hence, no datagaps were identified, the study meets fully the tonnage-driven data requirements under REACH and not further testing needs to be performed.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.
