Description of key information
Based on the results of a reliable ready biodegradability study with a structural analogue Norethyl, Norethylac is considered to be not readily biodegradable.
Additional information
In a 28 day test performed according to OECD guideline 301B (modified Sturm test) and GLP principles with a structural analogue of Norethylac, Norethyl,, the test item did not reach the pass level of 60% for ready biodegradability, neither within the 10 -d window nor after 28 days of incubation. The test item was tested in duplicate and showed 0% biodegradation in both bottles tested. Therefore, it is designated as not readliy biodegradable. All the criteria for acceptability of the test were met and the study is considered reliable without restrictions. This result can be read across to Norethylac.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
