Description of key information

The substance Blankophor TP 0306 is assumed to be stable in water.

Key value for chemical safety assessment

Additional information

No study is available for Blankophor TP 0306 (CAS 32257-57-1). Thus a read-across is performed to a study conducted with the structural analogue CAS 16470 -24 -9. The test was conducted according to the EEC-guideline L251/C.10 and equivalent to OECD 111 following GLP-requirements (Ciba-Geigy, BASF SE, 1992). The results of the test show that the substance is stable (hydrolysis below 10%) at pH 4, 7 and 9 at 25 °C with a half-life greater than 1 year.

From the results of the study it is assumed that the structural surrogate Blankophor TP 0306 (CAS 32257-57-1) is stable in water as well.
