Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

The assessment of the environmetal fate and pathway is done by considering data obtained from studies on Similar Substance 01. Justification for Read Across is given in Section 13 of IUCLID.

The substance is not considered as readily biodegradable since after 28 days maximum 40 % of substance could be degraded. Even if the substance is not readily biodegradable some percent is degraded in the water. In addition, the substance is hydrolytically stable at pH 4, 7 and 9 at 25 °C since less than 10 % is hydrolysed after 5 days. Under simulated gastric conditions (0.1 M HCl / pH 1.2 / 37 °C) 75 % of the substance was hydrolyzed to form dioctyltin chloro-(2-ethylhexyl thioglycolate) (DOTCE). Based on the above mentioned results the substance is expected to be found in water for a long period since it does not readily biodegraded nor it is hydrolysed. Predicted data on the substance (BCFBAF v3.01, EPI Suite 4.11) of 100 l/kg wet-wet suggests that the potential to bioaccumulate is low. Predicted values of the adsoprtion coefficient of the substance show that the substance could be adsorbed in the soil phase, however, these values should be considered with caution since the predicted value of LogKow used for the calculation of Koc was outside of the model's applicability domain. To sum up, the substance is practically insoluble in water and is not expected to readily biodegrade or hydrolyse. Despite the fact that it is not biodegraded the substance is not expected to bioaccumulate. By taking in consideration the high adsorption coefficient the substance could be adsorbed to the soil or sediment.
