Description of key information

Readily biodegradable: 69 - 95 % (O2 consumption) after 28 d (OECD 301F) 

Key value for chemical safety assessment

Additional information

Data on the ready biodegradability of Glycerides, C16-18 mono- (CAS 91052-47-0) are not available. Therefore, data on the ready biodegradability of the structurally related analogue substance Glycerides, C14-18 mono- and di- (CAS No. 67701-33-1) is used as read-across in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. The test was conducted according to a method equivalent to OECD Guideline 301D, under GLP conditions (Richterich, 1991). Activated sludge was exposed to the test substance for 28 days at 20°C, and biodegradation measured by O2consumption. After 28 days, the test substance reached 95 % (2 mg/L test concentration) and 69 % (5 mg/L test concentration) biodegradation. Based on the results for the read-across substance Glycerides, C16-18 mono- (CAS 91052-47-0) is considered as readily biodegradable.
