Description of key information
As described in the physical and chemical properties summary, the registered substance is a liquid of very low water solubility and very low volatility.
The registered substance is not readily biodegradable but strong and consistent evidence of significant mineralisation was provided. Therefore, the registered substance is inherently biodegradable (not fulfilling specific criteria) and not persistent in the environment. Delta-Damascone mercapto acetic acid (DD-ma) was identified as the main degradation product. This compound is slowly degraded and in the absence of other biodegradation studies on this metabolite, DD-ma is considered as potentially persistent (P) or very persistent (vP). All larger metabolites found can be considered as transient intermediates.
Regarding the bioaccumulation potential, with a measured log Kow value at 9.5, the registered substance would not be expected to bioaccumulate significantly. This statement was confirmed with an experimental bioaccumulation study, performed for a Japanese notification on the registered substance, and showing a BCF value lower than 38. The registered substance is not considered as bioaccumulable. Also, the final degradation product of the registered substance, DD-ma, is not expected to bioaccumulate significantly in the environment with a log Kow at 3.1 (arithmetical mean value of QSAR results).
Finally, the adsorption coefficient (Koc) of the registered substance was estimated by the KOCWIN v2.00 model to be 1953500 L/kg (log Koc = 6.3), using an experimental log Kow value at 9.5, indicated that the registered substance is immobile in soil (according to P.J. McCall et al., 1981).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
