- Irritant / corrosive response data:
- To evaluate the classification of the substances according to CLP Regulation, the raw data were reinterpreted.
The mean value from gradings at 24, 48 and 72 hours after patch removal calculated in at least 2 of 3
tested animals were the following:
- erythema/eschar: score 0/6=0 (3 out of 3 animals)
- oedema: 0/6=0 (3 out of 3 animals) - Other effects:
- None reported
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The results allows clear decision that the substance p-Nitrobenzoic acid, compound with 2,2',2''-nitrilotriethanol (1:1) is not corrosive and not irritating to skin according to the regulation 1272/2008/EC after reinterpretation of the raw data.
- Executive summary:
A study was performed to assess the irritation potential of the test material p-Nitrobenzoic acid, compound with 2,2',2''-nitrilotriethanol (1:1) to the skin of the New Zealand White rabbit (SPL Standard Test Method 540.06). The method followed OECD Guidelines for Testing of Chemicals (1992) No. 404 "Acute Dermal lrritation/Corrosion" and Method 84 of Commission Directive 92l69lEEC (which constitutes Annex V of Council Directive 67l54SlEEC).
The results may be used as a basis for classification and labelling according to the Regulation 1272/2008/EC after reinterpretation of the raw data.
A single 4-hour semi-occluded application (0.5 ml) of the test material was administered to the intact skin of three rabbits. Skin reactions were recorded 1, 24, 48 and 72 hours after administration.
The mean value from gradings at 24, 48 and 72 hours after patch removal calculated were the following:
- erythema/eschar: score 0/6=0 (3 out of 3 animals)
- oedema: 0/6=0 (3 out of 3 animals)
No evidence of skin irritation/corrosion was noted. The test material is not corrosive and not irritant to skin according to the regulation 1272/2008/EC.
