Additional information

The ready biodegradability of citronellyl acetate was tested in three different studies. Two were performed according to OECD guidelines 301 B and 301 F, respectively using activated sludge as inoculum. At test termination after 28 days Unilever reported a degradation rate of 82.1 % and the 10-day window criteria was fulfilled. However, due to technical deficiencies, both studies have been disregarded. To cover the information requirements, a third study on ready biodegradability according to OECD guideline 310 (Headspace Test) for testing volatile substances was performed. The degree of biodegradation after an exposure period of 28 days was 93 ± 7 %. The results in this study are consistent with all validity criteria and the test is valid according to the guideline of this study. Accordingly, citronellyl acetate is considered readily biodegradable according to OECD criteria.
