Description of key information

The substance can be considered as hydrolytically stable.

Key value for chemical safety assessment

Additional information

The hydrolysis of 'zinc phthalocyanine sulfonate' was investigated under GLP conditions according to OECD guideline 111 (BASF AG 2012). The test was performed at pH 4.0, 7.0 and 9.0 at a temperature of 50°C. After 5 days of incubation, no hydrolysis was observed. Therefore, the substance can be considered as hydrolytically stable.
