- Irritant / corrosive response data:
- There were no erythema and edema observed at any given timepoint.
- Other effects:
- Pretest with one animal was performed to determine the corrosive properties of the test material. Therefore the exposure was terminated after 3 minutes, 1 and 4 hours and scored, respectively. Every scored timepoint for erythema and edema was 0.
No further local or systemic effects were observed during the study period.
No effects on body weight (gain) were noted.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material caused under the conditions of the test of "Acute dermal irritation/corrosion" (OECD 404) no symptoms of irritation/corrosion.
- Executive summary:
The test material caused under the conditions of the test of "Acute dermal irritation/corrosion" (OECD 404) no symptoms of irritation/corrosion.
The individual mean values of the erythema/eschar and edema from gradings at 24, 48 and 72 hours were 0 in all three animals. Therefore, the test material is "not classified" according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and according to the Regulation (EC) No 1272/2008 on classification, labelling and packaging (CLP) of substances and mixtures.
