- Reversibility:
- fully reversible within: 24 h
- Irritant / corrosive response data:
- No corneal opacity or iritis was observed in any treated eye during the study. One hour following test substance instillation, all treated eyes exhibited conjunctivitis. All animals were free of ocular irritation within 24 h.
- Other effects:
- Apart from the eye irritation noted, all animals appeared active and healthy. There were no other signs of gross toxicity, adverse pharmacologic effects or abnormal behavior.
Any other information on results incl. tables
Under the conditions of this study niacin-bound chromium is practically non-irritating to the eye.
