Description of key information
Pour point: -65 °C at 101 kPa (75 % aqueous solution of Choline bicarbonate, ASTM D97-08)
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -65 °C
Additional information
The pour point of the 75 % aqueous solution of Choline bicarbonate was determined in a well-documented study according the relevant standard method ASTM D97-08. The pour point of the test item was determined reproducibly in two trials to be -65 °C, which in in the scientifically expected range. Hence, the results are reliable and can be used for further risk assessment. The determination of the pour point of a 75 % solution is reasonable because this is the marketed form, the substance is not isolated and is additionally hygroscopic.
The outcome of the study is reliable without restrictions, within the expected range and determined by a valid 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.
