Applicant's summary and conclusion
- Interpretation of results:
- other: Not sensitizing
- Conclusions:
- No local reactions (irritation or sensitisation) were seen in 207 human volunteers tested with daily skin applications of 5 % aqueous solution of the test chemical.Thus it was considered that test substance was not sensitizing to human skin.
- Executive summary:
A skin sensitization study was performed to evaluate the skin sensitization potential of the test chemical on 207 human volunteers.
5% aqueous solution pf the test chemical was applied during induction and challenge process. Induction phase was subjected three times per week for three weeks which was followed by challenge application after 12 days. No local reactions of sensitisation was seen in 207 human volunteers
Thus it was considered that test substance was non sensitization to human skin.
