Description of key information
Additional information
Abiotic degradation:
The study on hydrolysis was technicaly not feasible due to the multiconstituent nature of the substance and the low water solubilities of the individual components. Nevertheless, due to the structural properties of the two components of the substance (monoester and diester), hydrolysis of both components can be expected.
Biodegradation:
In a study following OECD guideline 301 B a degradation rate of 24 % and 12 % was determined. Furthermore, it could be shown that the monoester component of the substance undergoes primary degradation. For the diester component primary degradation could not be detected which could be due to the very low solubility of the substance. Nevertheless, due to the ester group it is expected that the diester component undergoes hydrolysis. This could further ease primary degradation similar to the monoester component.
Further degradation tests on an analogous substance were performed according to OECD guideline 308 (water / sediment simulation tests). In these studies the primary degradation from water and sediment goes rapidly (DT 50 approx. 8 days). However, the mineralization was insignificantly low (approx. 1%).
Bioaccumulation:
Two guideline studies on the bioconcentration of the substance in fish are availabe. Here, bioconcentration factors of < 0.24 to 34 were determined. Hence, the substance does not significantly accumulate in organisms.
Transport and distribution:
The study on adsorption/desorption was technically not feasible. Nevertheless, the single pretest results clearly demonstrated that the substance highly adsorbed to soil. Furthermore, different calculations revealed a partition coefficient > 3, which indicates immobility in soil and adsorption to suspended particle for the components of the UVCB substance. Additionally, no volatilisation is expected. Thus, the UVCB substance will mainly distribute to soil and sediment.
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).
