Executive summary:

Quevauviller et al. (1964) and Quevauviller (1965) applied CFC-11, CFC-12, CFC-114, and mixtures of CFC-11 and CFC-12 and of CFC-11 and CFC-22 were applied once a day, 5 days/week for 1 month to the eye of rabbits.

Slight irritation was noted only in the eye of the rabbits; the effects are not considered to result in classification. The study cites an exposure period of 1 month, which is above the specified exposure time requirements of the current guidelines. Hence the results are deemed to be appropriate.

It should be noted that the substance is a gas, and as such, prolonged exposure to the eye is not anticipated. Following exposure, evaporation would occur, resulting in rapid removal from the site, hence minimising the effects of acute exposure. 

It should also be noted that in accordance with section 2 of REACH Annex XI, the study does not need to be conducted as the substance is a gas. Hence the data provided is considered appropriate for assessment of this endpoint as supporting information only.
