Biodegradation in water:
under test conditions no biodegradation observed

Additional information

As no study is available for Blankophor TP 0306 (CAS 32257 -57 -1), read-across is performed to a study conducted with the structural analogue CAS 16470 -24 -9. In this GLP-study biodegradation of the test substance was determined under aerobic conditions according to the OECD guideline 301 A (BASF, Ciba-Geigy, 1992). After 28 -days of exposure the biodegradation of the test substance was 1.2% based on DOC-removal. Thus, under test conditions no biodegradation could be observed.

Concluding for Blankophor TP 0306, no biodegradation is expected.
