Additional information
Justification for classification or non-classification
Skin irritation:
Based on OECD 430 GLP study, Cobalt Phthalocyanine did not show evidence of skin corrosive effect. However, these results have to be considered as part of an integrated approach.
It can be noted that usually, this result should be considered together with in vitro assays to assess skin-irritating properties of the test material. Nevertheless, regarding the chemical structure (metal compound insoluble in water and octanol) of the substance, carrying these kinds of assays is not feasible Therefore, only OECD 430 test has been performed.
Besides, from data on 29H,31H-phthlalocyanine (EC number: 209 -378 -3, CAS number: 574 -93 -6) on ECHA website, only 2 of 82 notifiers reported that this substance require a classification for skin irritating (Cat 2).
For cobalt, a harmonised classification is available, and no skin irritating property have been identified (refer to Annex VI of CLP Regulation).
To conclude, in a weight of evidence approach and in order to avoid unnecessary testing on animals, considering all the elements listed above, it can be concluded that Cobalt Phthalocyanine does not have skin irritating potential.
Eye irritation
According to Annex VII, column 2, only in vitro studies are foreseen. Therefore, 2 in vitro studies using Cobalt Phthalocyanine as test item have been provided in the IUCLID dossier:
- one GLP study performed according to OECD 438 (2013), Klimisch 1, with the following conclusion:" no prediction can be made".
- one GLP study performed according to OECD 492 (2015), Klimisch 1, with the following conclusion: "Cobalt Phthalocyanine is not considered as eye irritant or serious eye damage according to CLP criteria".
To conclude, Cobalt Phthalocyanine does not require classification according to CLP criteria.
