Irritant / corrosive response data:
Corneal injury was seen in one animal as opacity (fmax. grade 1) and epithelial damage (max. 25% of the corneal area). The corneal injury had resolved within 72 hours?
Irridial irritation (grade 1) was observed in two animals after 1 hour only. Irritation of the conjunctivae was seen as redness, chemosis and discharge, which had completely resolved within 72 hours in all animals.
Other effects:
Colouration: remnants of the test substance were present in the eyes of all animals on day 1.

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Guidelines in Commision Directive 93/21/EEC), F-2200HM does not have to be classified and has no obligatory labelling requirement for eye irritation.
Executive summary:

Acute eye irritation/corrosion study with F-2200HM in the rabbit.

The study was carried out based on the guideline described in: EC Commission Directive 92/69/EEC, B., Acute Toxicity. Eye irritation and OECD No. 405, 'Acute Eye Irritation/Corrosion'.

Single samples of approximately 100mg of F-2200HM (a volume of approximately 0.1ml) were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours after instillation.

Instillation of the test substance resulted in effects on the cornea, iris and conjunctivae.

Corneal injury was seen in one animal as opacity (max grade 1) and epithelial damage (max. 25% of the corneal area). The corneal injury had resolved within 72 hours.

Irridial irritation (grade 1) was observed in two animals after 1 hour only. Irritation of the conjunctivae was seen as redness. Chemosis and discharge which had completely resolved within 72 hours in all animals.

Remnants of the test substance were present in the eyes of all animals on day 1.

Based on these results and according to the EC criteria for classification and labelling requirements for dangerous substances and preparations (Guidelines in Commission Directive 93/21/EEC). F-2200HM does not have to be classified and has no obligatory labelling requirement for eye irritation.
