Applicant's summary and conclusion
- Interpretation of results:
- other: not sensitizing
- Conclusions:
- No sensitizing effects were observed for 1H-Isoindole-1,3(2H)-dione, 2-(cyclohexylthio)- when In vitro Shelanski Repeated Insult Patch Test was performed.
- Executive summary:
In vitro Shelanski Repeated Insult Patch Test was performed on human subjects to observe the skin sensitizing effects of 1H-Isoindole-1,3(2H)-dione, 2-(cyclohexylthio)-.
Patches, 1" square of the rubber stock were applied to the skin of 53 human volunteers and left in place for 24 hours. Readings were taken at the end of 24 hours, and the sites were rested for an additional 24 hours. Patches were reapplied and read again after 24 hours. Fifteen such applications were used. A 10-day rest period followed, and then the challenge application was applied for 24 hours.No positive reactions were observed following the initial application, any subsequent application or after the challenge application. Only mild cumulative irritation was observed in this study. The level used in this study, 2 parts per hundred rubber (2 phr) is about five times higher than what is normally used in compounded rubber stocks. Therefore 1H-Isoindole-1,3(2H)-dione, 2-(cyclohexylthio)- was considered to be non sensitizing in Human by in vitro Shelanski Repeated Insult Patch Test
