One animal with abraded skin showed very slight erythema (grade 1) at the 24 hour time point. After 72 hours no skin reactions were observed in any of the rabbits.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Caprinoguanamine was not irritating to skin. There were no skin effects observed in any animal with intact skin at 24 and 72 hours.
- Executive summary:
In a primary dermal irritation study according to US FHSA Federal regulation: 16 CFR 1500.41 and similar to OECD Guideline 404, adopted 24 April 2002, 6 adult New Zealand white rabbits with intact skin were dermally exposed 24 hours to 0.5 g of Caprinoguanamine on 6.45 cm² skin surface. Animals were then observed for 72 hours. In addition, 6 rabbits with abraded skin were exposed under the same conditions.
Irritation was scored by the method of Draize (J. Pharmacol. 82 (1944) 377-390) and the CIVO-grading system (1973).
There were no skin effects observed in any animal with intact skin at 24 hours. One animal with abraded skin showed very slight erythema (grade 1) at the 24 hour time point. After 72 hours no skin reactions were observed in any of the rabbits. The result of the study is regarded as relevant and reliable although there are protocol deviations from the OECD 404 guideline (longer exposure time, shorter observation time).
In this study, Caprinoguanamine is classified as not irritating to rabbit skin according the criteria of CLP, EU GHS (Regulation (EC) No 1272/2008).
