Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitising
- Conclusions:
- No skin reactions indicative of sensitisation were found. Thus, the the test chemical can be considered to be not a skin sensitizer.
- Executive summary:
The skin sensitization study of the test chemical was assessed in guinea-pigs.Group of ten male and ten female guinea pigs were given several intra-dermal injections of 0.1% of benzotriazole in saline together with an adjuvant. This was followed 2 weeks later by a challenge intra-dermal injection using the same concentration and, after a further 1 week, a 24-48- hour covered dermal application using a 30% solution in petroleum.
No skin reactions indicative of sensitisation were found. Thus, the the test chemical can be considered to be not a skin sensitizer.
