Additional information

The test substance proved to be inherently and ultimately biodegradable in tests based on OECD 301F and 302C. Based on the analysis of metabolites in the key study, it can be as well concluded that the test substance and its degradation products are not persistent.


As the test substance hydrolyses quite fast under environmental conditions (pH7) with a half-life of only 9 days, the substance can be regarded as rapidly degradable under environmental conditions. With a half-life time of < 16 days the criteria for rapid degradation according to the CLP/GHS criteria are as well fulfilled as the degradation products salicylic acid (2-hydroxylbenzoic acid) [CAS 69-72-7] and 3,3,5-trimethylcyclohexanol [CAS 116-02-9] are not classified as hazardous to the aquatic environment.


The substance is has a moderate volatility from the water surface under environmental conditions (estimated Henry’s law constant: 37.4 Pa· m3/mol; 20°C).


Due to the calculated high log Koc of 4.28 L/kg (mean of MCI and Kow method) the substance is considered to be immobile in soil and sediments according to the classification scheme of McCall et al. (1981).


Despite the high log Kow of 6.27, bioaccumulation in aquatic species is not expected as the BCF estimated with the method of Arnot and Gobas is 224.4 L/kg ww considering that the substance has a half-life in fish of less than a day.
