Description of key information

The substance Blankophor TP 1160 is assumed to be stable in water.

Key value for chemical safety assessment

Additional information

As no study is available for Blankophor TP 1160 (CAS 1200448-68-5), a read-across is performed to a study conducted with the structural analogue CAS 16470-24-9. The test was conducted similar to OECD guideline 111 following GLP-requirements (Ciba-Geigy, BASF SE, 1992). The results of the study show that the substance is stable in water (hydrolysis below 10%) at pH 4, 7 and 9 at 25 °C. Thus, pH independent the half-life for hydrolysis is greater than 1 year.
