Description of key information

There is one study (Currenta, 2009) that assessed ready biodegradability within 28 days and gave a degradation of 27 % for Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane. Thus, the substance is not considered to be readily biodegradable" (Currenta, 2009). Furthermore, there is a study (Currenta, 2009) that assessed inherent biodegradability within 27 days, giving a degradation of 42% for Benzenediamine, ar-methyl-, polymer with 2-methyloxirane and oxirane. The substance is considered to be inherently biodegradable, not fulfilling specific criteria.
