Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

TIB KAT 223 hydrolyses in water directly in di-n-octyltin oxide and 2,4-pentadione. So there is to evaluate the aquatic toxicity of the hydrolysis compounds.

Di-n-octyltin oxide may not soluble enough to cause adverse short time effects in fish. So this endpoint refers to the short time toxicity in fish for 2,4 -Pentadione.

So for the hydrolysis product Dioctlytin oxide in accordance with column 2 of REACH Annex IX, the long-term testing study does not need to be conducted as the chemical safety assessment concludes that the substance is of no immediate concern to the environment. The available data are adequate for classification and labeling purposes and PBT assessment, so no further testing is required.

Conclusion on classification

Classification as "Aquatic Chronic 3" - H412 by order of ECHA and MSCA, data do not support this classification and labeling
