Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with REACH Annex VIII column 2, the study does not need to be conducted if the substance is highly insoluble in water.

Key value for chemical safety assessment

Additional information

Supporting information was available in the form of Yoder (2003). The study used a non-standard technique measuring the behaviour of dioctyltins in water by electrospray ionisation mass spectrometry (ESI/MS). The study was performed and reported to a high standard and as such was assigned a reliability score of 2 in line with the criteria for assessing data quality, as outlined in Klimisch (1997). Although the registered substance was a point of interest in the study, the poor solubility in both water and suitable solvents meant that the test substance was not present at a detectable level, and it was not possible to use a surrogate substance to create standards. No conclusions on the hydrolysis of the test substance could be drawn from the available data.
