Description of key information

Readily biodegradable: 79.5% in 28 days (OECD 301B)

Key value for chemical safety assessment

Additional information

A study evaluating the potential for ready biodegradability of Glycerides, C12-18 di- and tri- (CAS No. 91744-28-4) is available (Flach, 2012). The test was conducted according to OECD Guideline 301B, under GLP conditions. Activated sludge microorganisms were exposed to the test substance for a period of 28 days, and biodegradation followed by measuring the CO2 production in the test vessels. After 28 days, the test substance reached 79.5% biodegradation, and therefore, it can be considered as readily biodegradable. The results obtained in the toxicity control (55% biodegradation within 14 days) show that Glycerides, C12-18 di- and tri- is not toxic to and therefore non-inhibitory of activated sludge microorganisms activity.
