- Irritant / corrosive response data:
- 24 hours after Caprinoguanamine had been brought into the eyes very slight corneal opacity and slight iritis in one rabbit and slight conjunctivitis in all six rabbits were observed. In the course of the seven day observation period all lesions recovered completely, so that at the seventh day reading all eyes were normal again.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 24 hours after Caprinoguanamine had been brought into the eyes very slight corneal opacity and slight iritis in one rabbit and slight conjunctivitis in all six rabbits were observed. In the course of the seven day observation period all lesions recovered completely, so that at the seventh day reading all eyes were normal again.
- Executive summary:
In a primary eye irritation study similar to OECD guideline 405, 2nd October 2012, 100 mg of Caprinoguanamine was instilled into the conjunctival sac of 6 adult New Zealand white rabbits. Animals then were observed for 7 days. Irritation was scored by the FDA scoring scale. 24 hours after Caprinoguanamine had been brought into the eyes very slight corneal opacity and slight iritis in one rabbit (score 1) and slight conjunctivitis (score 1) in all six rabbits were observed. All lesions were fully reversible within the 7 day observation period.
In this study the mean grades of ocular reactions at 24, 48 and 72 h after instillation were lower than the values classified as irritant by the Directive 67/548/EEC as well as GHS Regulation EC No 1272/2008.
When administered to the eye, the test article Caprinoguanamine is classified as "non-irritant".
