Reference
The test substance was not able to reduce MTT directly.
No reduction of viability was observed in the corrosion test. The irritation test was conducted as four separate tests, one of which was disregarded due to a technical error. The viability of test substance treated samples was 44.1±27.6%, 32.1± 59.7%, and 9.8 ± 54.9%. Although the coefficient of variation is high, overall the data are sufficient to assess the irritation potential of the test substance.

- Guideline:
- OECD Guideline 437 (Bovine Corneal Opacity and Permeability Test Method for Identifying Ocular Corrosives and Severe Irritants)
- Principles of method if other than guideline:
- EpiOcular(TM): The objective of this in vitro test is to assess the eye irritation potential of the test substance using the reconstructed human ocular model EpiOcular(TM). The test is based on the experience that irritant chemicals produce cytotoxicity in human reconstructed cornea after a short term topical exposure. After application of the test material to the surface of the EpiOcularTM tissue the induced cytotoxicity (= loss of viability) is measured by a colorimetric assay.

Reference
The test substance was not able to reduce MTT directly.
Only a slight reduction of viability was observed in the EpiOcularTM test. Since the data from the EpiOcularTM test alone were sufficient for assessment of the eye irritation potential of the test substance, no further tests were conducted.

- no study available
Additional information
In vitro skin irritation and corrosion testing was performed with a turnkey strategy. Corrosivity and potential for irritation were assessed as ability of the test substance to decrease tissue viability. While the test substance was not corrosive (tissue viability >90%) , it was irritating in the EpiDerm(TM) assay under the test conditions chosen (tissue viability <50%).
Eye irritation testing was performed in vitro with the EpiOcular(TM) test, in which the irritation potential of the test substance is assessed as its ability to decrease tissue viability. The mean tissue viability was >80%, therefore the test substance did not show potential for eye irriation in the EpiOcular(TM) test under the test conditions chosen.
Justification for selection of skin irritation / corrosion endpoint:
GLP- and guideline-conformant study
Justification for selection of eye irritation endpoint:
GLP- and guideline-conformant study
Effect level: empty Endpoint conclusion: Adverse effect observed
Justification for classification or non-classification
1,3,5-Benzenetricarboxylic acid, copper(2+) salt showed a skin irritation potential in the EpiDerm(TM) test in vitro. Therefore, according to Regulation (EU) 1272/2008 (CLP) classification as irritating to skin (Cat. 2, H315) is justified.
1,3,5-Benzenetricarboxylic acid, copper(2+) salt did not show eye irriation potential. Therefore, non-classification for eye damage is warranted.
