Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A TGD-approved handbook states that the substance is “miscible with water”. No numerical value for concentration or information on solution temperature or pH was reported.
Key value for chemical safety assessment
- Water solubility:
- 400 g/L
- at the temperature of:
- 20 °C
Additional information
The water solubility of DAA was sourced from two separate handbooks. Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Ed.) and Knovel Solvents - A Properties Database report that DAA is “miscible with water” or solubility of DAA was reported as “infinite mg/kg”, respectively. However, no numerical value for concentration or information on solution temperature or pH was reported in either source. Although the information from both sources is comparable, the data obtained from Knovel Solvents’ handbook is not TGD-approved, and as such is of Klimisch-4 reliability and is not considered valid.
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.
