Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The substance was considered to be a non-sensitiser based on a SI of less than 3 for all treatment groups.
- Executive summary:
In an in vivo local lymph node assay to evaluate the sensitisation potential of the substance mice (4 animals/treatment group) were exposed to the substance for 3 consecutive days at concentrations 10%, 25% or 50% w/w. Another group of 4 animals received the vehicle alone. The SI for all treatment groups was below 3 and thus indicates that the substance is not a sensitiser.
