Test animals
- Species:
- mouse
- Strain:
- other: CBA/CaCrl
- Sex:
- female
- Details on test animals and environmental conditions:
- The test was carried out on Nulliparous, non-pregnant female CBA/CaCrl strain mice. The sex and strain of mouse has been selected for this study in conformance with the design of the validated test method (OECD Guidelines for Testing of Chemicals Method 429, adopted 24 April 2002). Animals in the main study were in a body weight range of 16.9 to 20.5 g on the day before dosing commenced. Individual body weights were within ± 20% of the mean body weight for mice on the study. Based on information from the supplier the mice were approximately 8 to 10 weeks old on Day 1.

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The Stimulation Index (SI) recorded for the test sample was 0.8 (10% w/v test sample), 1.2 (25% w/v test sample) and 1.3 (50% w/v) test sample. These values do not meet the criteria for classifying the substance as a skin sensitiser according to EU CLP criteria.
- Executive summary:
The skin sensitisation potential of the substance was tested in accordance with the OECD Guideline for Testing of Chemicals 429. Groups of four female CBA/CaCrl mice were subjected to topical applications of vehicle or of one of the test formulations (at concentrations of 10, 25 or 50% w/v) to the outer aspect of the auditory pinnae once daily on Days 1, 2 and 3. The Stimulation Index (SI) recorded for the test sample was 0.8 (10% w/v test sample), 1.2 (25% w/v test sample) and 1.3 (50% w/v) test sample. These values do not meet the criteria for classifying the substance as a skin sensitiser according to EU CLP criteria.
