Description of key information

The conclusion that 2-Propyn-1-ol, polymer with ethylene oxide (>1 <2.5 mol EO) was readily biodegradable in this carbon dioxide evolution test based on the quantitative determination of the formed carbon dioxide in the test substance assays by comparison with the calculated maximal theoretical carbon dioxide production. The required pass level for ready biodegradability was reached. The degree of biodegradation after an exposure period of 28 days was 70-80 %.
CO2/ThCO2 in this test.
