- Irritant / corrosive response data:
- AVERAGE SCORE (24+48+72 hour) rinsed
- Cornea: individual scores all 0 (group mean score 0)
- Iris: Individual scores all 0 (group mean score 0)
- Conjunctivae (Redness): individual scores 0.3, 0, 0.3 (group mean score 0.2)
- Conjunctivae (Chemosis): individual scores 0.3, 0, 0.3 (group mean score 0.2)
- Overall irritation score: Maximum mean total score 4.7 at 1 hours after instillation.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The in vivo eye irritation study for Alcohols, C9-11-branched and linear, conducted according to a protocol similar to OECD Test Guideline 405 and in compliance with GLP, concluded Alcohols, C9-11-branched and linear to be not irritating to eyes.
