Endpoint summary
Administrative data
Description of key information
Based on the available data for the various test chemicals and applying the weight of evidence approach, it can be concluded that the test chemical will also behave in similar manner. The test chemical was estimated to be not sensitizing to skin. Thus it can be further classified under the category “Not Classified” as per CLP regulation.

- Executive summary:
The skin sensitization potential of the test chemical was assessed based on the available results from the various test chemicals.
Buehler test was conducted to assess the dermal sensitization potential of the test chemical. The study was performed according to OECD Guideline 406 Guidelines. 20 Dunkin Hartley guinea pigs were used for the study.
In induction, the animals were induced dermally at concentration of 42.8 %. After induction, animals were challenged dermally with the same concentration under occlusive conditions (duration of exposure not mentioned). The guinea pigs were observed for signs of dermal irritation and sensitization (observation duration not mentioned).
No known skin reactions were observed at induction as well as at challenge exposure. Thus the test chemical was considered to be not sensitizing to the skin of Dunkin Hartley guinea pigs.
This is supported by the results of skin sensitization study performed in 20 guinea pigs to observed its sensitizing potential by guinea pig maximization test.
The test chemical failed to induce any signs of dermal sensitization through out the test duration. Hence, the test chemical can be considered to be not sensitizing to skin.
The above results are further supported by the results of Human repeat insult patch performed to assess the dermal sensitization potential of the test chemical. 0.5% aqueous solution of the test chemical in 0.1% aqueous granular detergent was exposed to human skin and observed for dermal reactions(duration not mentioned). No evidence of dermal sensitization was observed when 0.5% aqueous solution of the test chemical in 0.1% aqueous granular detergent was exposed to human skin. Hence, the test chemical can be considered to be not sensitizing to skin.
Based on the available data for the various test chemicals and applying the weight of evidence approach, it can be concluded that the test chemical will also behave in similar manner. The test chemical was estimated to be not sensitizing to skin. Thus it can be further classified under the category “Not Classified” as per CLP regulation.

Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The results of the experimental studies from the various test chemicals indicate a possibility that the test chemical can be not sensitizing to skin.
Hence, by applying the weight of evidence approach,the test chemical can be considered to be not sensitizing to skin.
