Description of key information

In contact with water the substance will hydrolyse slowly. Hence, it is not expected to be an important fate path.

Key value for chemical safety assessment

Additional information

A study, cited in the OECD SIDS 2004 and originally performed by DuPont (1988) indicates, that hydrolysis of N,N-dimethylacetamide (DMAC) is expected to occur only in very small amounts in acidic and alkaline solutions. These findings are supported by the results of a test performed by Nellis (1965) and by a statement within the Hazardous Substance Database (Toxnet), that DMAC will probably hydrolyse slowly within the aquatic environment. Due to these results the aquatic tests are supposed to be valid as the test substance is assumed to be stable within the test solutions during the test performance.
