Biodegradation
Biodegradation in water:screening tests
Data of following studies are demonstrating rapid biodegradationAlcohols, C16-18 under aerobic conditions.
Morris, P.A., Filler, P.A., and Nielsen, A.M. (1991) conducted OECD 301B test and the result is that 21-65% at 20 mg/Lof Degradation was achieved within 28 days. The test substance required 5 extra days for a total of 15 days to reach 60% of maximum theoretical carbon dioxide production.The substanceachieved ready test pass levels, but not within the 10 day window.
Henkel KGaA. , 1999conducted OECD 301D test for Biodegradation of Alcohols, C16-18.
58% degradation was attained by day 7, the substance and 81% by day 28 and the substance is considered to be readily biodegradable.
Henkel KGaA. , 1999conducted ISO Draft (BOD Test for Insoluble Substances) test for Biodegradation of Alcohols, C16-18.
Degradation was 56 - 62 % after 28 day(s) , the substance is considered to be readily biodegradable.
Henkel KGaA. , 1999 conducted also another ISO Draft (BOD Test for Insoluble Substances) test for Biodegradation of Alcohols, C16-18.
Degradation was 81 - 100 % after 28 day(s) , the substance is considered to be readily biodegradable
The BIOWIN QSAR predicts that the substance Alcohols, C16-18 will be readily biodegradable.

Biodegradation in water and sediment: simulation tests
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE”, a simulation testing on ultimate degradation in surface water, the study does not need to be performed if the substance is ready biodegradable. As Alcohols, C16-18 is ready biodegradable a ready biodegradability study does not need to be conducted.
Therefore testing for Biodegradation in water does not need to be performed
Biodegradation in soil
Expert Judgement
If released to soil, Alcohols, C16-18 is expected to have low mobility based upon an estimated Koc of 4658. Volatilization from moist soil surfaces is not expected to be an important fate process.
Therefore testing for biodegradation in soil does not need to be performed.
