Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

Short-term measured data for the registered substance (Ureidopropyltrialkoxysilane, mixed methoxy and ethoxy esters) were available for fish, invertebrates and algae.

The test substance shows no toxicity up to 100 mg/l. Ureidopropyltrialkoxysilane, mixed methoxy and ethoxy esters hydrolyses rapidly in contact with water to the corresponding [3 -(trihydroxysilyl) propyl]urea, methanol and ethanol

Ecotoxicity data were predominantly generated on the parent compound, which was supposed to display the principal aquatic hazard; the results of each of these studies are interpreted with reference to nominal concentrations of the test substance. However, it is likely that the test organisms were also exposed to the hydrolysis products of the substance. It can be concluded that the hydrolysis products shows also no toxicity up to the highest tested concentrations in the studies and exposure to the possible degradation products did not induce additional effects on survival.

Ureidopropyltrialkoxysilane, mixed methoxy and ethoxy esters (116912-64-2) is not classified for the environment according to Regulation EU (67/548/EEC annex 1) and not classified according to the Regulation (EC) No.1272/2008 (CLP); there are no long-term data available.
