Endpoint conclusion
Endpoint conclusion:
no adverse effect observed (not sensitising)
Additional information:

Key study: The test item was assessed for skin sensitization potential using the Buehler topical closed patch technique, according to US EPA 798.4100 (GLP study). In a preliminary test, the test item was found to be slightly to moderately irritating at a concentration of 100% and non-irritating at a concentration of 50%. Based on these results, the test item at a concentration of 100% was applied for 6h under a closed patch, once a week for 3 weeks during the induction phase, and once for 24h during the challenge phase. Challenge with the test item following 3 weeks of induction caused no erythema or edema in 10/10 treated animals. No reactions were noted in the negative control group, and 4/4 animals reacted in the positive control group. Consequently, the test item was not considered a skin sensitizer.

Endpoint conclusion
Endpoint conclusion:
