Description of key information
Biodegradation in water
The Ready Biodegradability of test chemical was determined by the Manometric Respirometry Test according to the OECD Guidelines for Testing of Chemicals, Method No. 301 F. The test chemical undergoes 71% biodegradation after 28 days in the test conditions. The 10 -day window criterion is also fulfilled (16% biodegradation on day 4 and 65% on day 14). The curves obtained with the reference substance alone and with test chemical + reference substance show no toxic effect to the micro-organisms at the test concentration (100 mg/l). Thus, the test chemical should be regarded as readily biodegradable according to this test.
Biodegradation in water and sediment
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end point is scientifically not necessary and does not need to be conducted since the test chemical is readily biodegradable in water.
Biodegradation in soil
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end point is scientifically not necessary and does not need to be conducted since the test chemical is readily biodegradable in water.

Biodegradation in water
Various experimental studieshas been investigated for the test chemicalfor reviewing the biodegradation endpointwhich have beensummarized as below;
The Ready Biodegradability of test chemical was determined by the Manometric Respirometry Test according to the OECD Guidelines for Testing of Chemicals, Method No. 301 F. The test chemical undergoes 71% biodegradation after 28 days in the test conditions. The 10 -day window criterion is also fulfilled (16% biodegradation on day 4 and 65% on day 14). The curves obtained with the reference substance alone and with test chemical + reference substance show no toxic effect to the micro-organisms at the test concentration (100 mg/l). Thus, the test chemical should be regarded as readily biodegradable according to this test.
The another Manometric Respirometry Test was conducted for test chemical to assess its percent degradation as per the OECD Guidelines for Testing of Chemicals, Method No. 301 F. The Test chemical undergoes 60% biodegradation after 28 days (65% after 36 days) in the test conditions. Biodegradation exceeds 10% on day 8 and reaches only 52% at the end of the 10-day window (days 8 to 18).The curves obtained with the reference substance alone and with Test chemical + reference substance show no toxic effect of Test chemical to the micro-organisms at the test concentration (100 mg/I).Thus, Test chemical should be regarded as readily biodegradable according to this test.
The above results were supported by Biodegradation study conducted according to OECD Guideline 301 B (Ready Biodegradability: CO2 Evolution Test) for 28 days for evaluating the percentage biodegradability of test substance. The percentage degradation of the test substance was determined to be 75.4% by using CO2 evolution parameter. Thus, based on percentage degradation of test chemical, the chemical was considered to be readily biodegradable in nature.
By considering results of all the studies mentioned above it can be concluded that the test chemical can be expected to be readily biodegradable in nature.
Biodegradation in water and sediment
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end pointis scientifically not necessary and does not need to be conducted since the test chemicalis readily biodegradable in water.
Biodegradation in soil
In accordance with column 2 of Annex IX of the REACH regulation, testing for this end pointis scientifically not necessary and does not need to be conducted since the test chemicalis readily biodegradable in water.
