Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test material failed to induce sufficient dermal irritation to be considered irritating to skin.
- Executive summary:
In this guideline (CFR 1500.41) study, the test material (unchanged) was administered topically to the intact skin of 6 rabbits. Results were measured at 24 and 72 hours using the draize scale. The test material failed to induce sufficient dermal irritation to be considered a dermal irritant.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
