Additional information

Abiotic degradation:

The estimated half-lives at 25°C of the test item are:

pH 4: Estimated half life at 25°C: 84.5 days

pH 7: Estimated half life at 25°C: 449 days

pH 9: Estimated half life at 25°C: >1 year

It has been observed that the rate of hydrolysis increases with a decrease in pH.

Biotic degradation:

The test substance was degraded 100% after 28 days in an OECD 306 study. Based on this the test material has a potential for biodegradation in the marine environment (and freshwater environment). The test substance is considered to be readily biodegradable based on these results.

Based on this data the substance is not considered to persist in the aquatic environment.
