Description of key information

According to structural properties, hydrolysis is not expected.

Key value for chemical safety assessment

Additional information

The Pigment Orasol Pink 478 (CAS 97862-65-2) is a multipartite chromium complex.

The assessment of the hydrolysis potential of Orasol Pink 478 is based on the available data for the 1:1 and 2:1 chromium complexes originating from synthesis as well as for the used counterions Rosin Amine D (CAS 61790-47-4) and Basic Violet 10 (CAS 81-88-9).

 

Assessment:

According to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), the chrome complex of Orasol Black Pink 478 (CAS 97862-65-2) as well as the counterions Rosin Amine D (CAS 61790-47-4) and Basic Violet 10 (CAS 81-88-9) are generally resistant to hydrolysis because they do not contain any labile functional groups. Therefore, no study on hydrolysis is performed.
