Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

The study on hydrolysis does not need to be conducted because the substance is readily biodegradable.

In a supporting study according to OECD guideline 111 the test item was completely hydrolyzed after 2 h at 50 °C.

Key value for chemical safety assessment

Additional information

The substance is readily biodegradable (cf. chapter 5.2). In Annex VIII of Regulation (EC) No 1907/2006, it is laid down that the study on hydrolysis does not need to be conducted if the substance is readily biodegradable.

Nevertheless, hydrolysis was investigated according to OECD guideline 111 [BASF AG, 2002]. In this study the test item was completely hydrolyzed after 2 h at 50°C. Hydrolysis was detected by measuring the formaldehyde content of the test solution.
