Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, salicylic acid is not irritating according to the Directive 2004/73/EC and to the GHS, second Revised Edition, 2007.
- Executive summary:
In a primary dermal irritation study, young adult New Zealand White rabbits (1 male and 2 females) were dermally exposed to 0.5 g of salicylic acid moistened with 0.5 mL purified water. Test sites were covered with a semi-occlusive dressing for 4 hours. Animals then were observed for 14 days. The skin reactions were assessed at 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after removal of the dressing. The mean score was calculated across 3 scoring times; 24, 48 and 72 hours after patch removal, for each animal separately.
The test item did not elicit any skin reactions at the application site at any of the observation times, all scores = 0. The individual mean score for erythema/ eschar and oedema for each of the 3 animals was 0.
Based upon the directive 2004/73/EC and the GHS classification, acid salicylic is considered as not irritating to the rabbit skin.
