Endpoint summary
Administrative data
Description of key information
Based on the available results and applying the weight of evidence approac, the test chemical can be considered to be not likely to be sensitizing to skin. Therefore, the test chemical can be classified under the category "Not Classified" as per CLP Regulation.

- Conclusions:
- Based on the available results and applying the weight of evidence approach, the test chemical can be considered to be not likely to be sensitizing to skin. Therefore, the test chemical can be classified under the category "Not Classified" as per CLP Regulation.
- Executive summary:
Various studies have been performed to evaluate the dermal sensitization potential of the test chemical. The results are summarized below:
Buehler test was performed to evaluate the dermal sensitization potential of the test chemical. The study was performed according to OECD 406 Guidelines. No dermal reactions were observed at the treatment sites of the test animals after exposure to the test chemical. Hence, the test chemical can be considered to be not sensitizing to skin.
The above result is supported by another Buehler test conducted on guinea pigs to determine the skin sensitization potential to test chemical.10 test guinea pigs, 10 negative controls, and 5 positive controls were used for the study. During induction, the test chemical moistened with distilled water was applied for 24 h, under occlusive patch at a concentration of 95% over a period of 3 weeks. Later the animals were challenged with same concentration and observed for skin reactions. The chemical failed to induce skin sensitization in treated guinea pigs and hence the test substance was considered as not sensitizing to the skin of Guinea pigs.
Based on the available results and applying the weight of evidence approac, the test chemical can be considered to be not likely to be sensitizing to skin. Therefore, the test chemical can be classified under the category "Not Classified" as per CLP Regulation.
