DETERMINATION OF CYTOTOXICITY
- Method: decrease in the number of revertants, clearing or diminution of the background lawn (= reduced his- or trp- background growth), reduction in the titer - Evaluation criteria:
- The test chemical is considered positive in this assay if the following criteria are met:
* A dose-related and reproducible increase in the number of revertant colonies, i.e. about doubling of the spontaneous mutation rate in at least one tester strain either without S-9 mix or after adding a metabolizing system.
A test substance is generally considered nonmutagenic in this test if:
* The number of revertants for all tester strains were within the historical negative control range under all experimental conditions in two experiments carried out independently of each other. - Species / strain:

Additional information
Experimental data on the target substance is not available. No structural alert for DNA damage was identified by the profilers in the OECD QSAR toolbox v3.3.0.152. (Q)SAR modelling using the software TIMES-predicted the substance to be non mutagenic, with the limitation that the structure is out of the applicability domain of the model.
No hazard for mutagenicity in the Ames test was identified for the closest structural analogue (CAS 73455-75-1) and for all related sulfonated copperphthalocyanine in GLP and OECD 471 compliant studies (see data matrix). The closest analogue substance has consists of isomers with lower molecular weight since it has a shorter alkyl chain. It is therefore considered suitable for the assessment of mutagenicity in the Ames test. The target substance is considered to be non mutagenic in bacteria.
Justification for classification or non-classification
Dangerous Substance Directive (67/548/EEC)
The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is not considered to be classified for mutagenicity under Directive 67/548/EEC, as amended for the 31st time in Directive2009/2/EG.
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for mutagenicity under Regulation (EC) No. 1272/2008, as amended for the fifth time in Directive EC944/2013.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
