Additional information

The hydrolysis potential of the registered substance was detemined in accordance with a method similar to the OECD Guideline for Testing of Chemicals 111 as part of a study of the behaviour of the test substance in water. Although there are some differing trends observed for the test data, there is no significant evidence for degradation of the test substance over the 7 day period of the study.

The ready biodegradability of the registered substance has been determined in accordance with the OECD Guideline for Testing of Chemicals 301B. After 28 days the biodegradation of the registered substance was recorded as 76.84% (based on CO2 evolution) and 72.03% (based on DOC). The substance is inherently biodegradable but not readily biodegradable. In addition, a formulated product containing the registered substance was found to show good potential for ultimate biodegradation, but was not considered to be inherently biodegradable. A formulated product containing the registered substance showed a low potential for biodegradation in seawater, with 28 day degradability rates of 29.6% at 2.5 mg/l and 22.1% at 3.5 mg/l. The test material was considered ultimately biodegradable but not readily biodegradable in seawater.
