Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions, Mexoryl SBF is not classified as irritating to skin according to the criteria of Annex VI to the Directive 67/548/EEC and CLP Regulation (EC) N° (1272-2008).
- Executive summary:
In a primary dermal irritation study performed according to OECD Guideline 404 and in compliance with GLP, three male New Zealand White rabbits were dermally exposed to 500 mg of Mexoryl SBF under a semi-occlusive dressing. The test item was first evaluated on a single animal and the duration of exposure was 3 minutes on the anterior left flank, 1 h on the anterior right flank and 4 h on the posterior right flank. Since the test item was not severely irritant on this first animal, it was then applied for 4 h to two other animals. After removal of the residual test item with moistened cotton pad, irritation was scored as outlined in the OECD Guideline 404 at 1, 24, 48 and 72 h after exposure.
A very slight erythema was noted in 1/3 animals from Day 1 up to Day 3. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0.7, 0 for erythema and 0, 0, 0 for edema score, respectively. In this study, Mexoryl SBF is not a skin irritant on male rabbits.
Under the test conditions, Mexoryl SBF is not classified as irritating to skin according to the criteria of Annex VI to the Directive 67/548/EEC and CLP Regulation (EC) N° (1272-2008).
