Any other information on results incl. tables
There were no signs of ill-health in any naimal during the study. Instillation into the eye caused practically no initial pain (class 1 on a 0 -5 scale). There were no corneal or iridial effects. Conjunctival effects consisted of slight redness in two animals for up to 1 day and slight chemosis in one animal approximately 1 hour after instillation only. There were no additional signs of irritation.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- 1,2,3,4-tetrachloro-hexafluorobutane is not an eye irritant.
- Executive summary:
The purpose of the study was to assess the eye irritation potential of 1,2,3,4-tetrachloro-hexafluorobutanet o rabbits.
The study was conducted in accordance with guidelines OECD 405 (1987), EU method B.5 (1992) and EPA OPPTS 870.2400 (1998).
A volume of 0.1 ml of 1,2,3,4-tetrachloro-hexafluorobutane was instilled into one eye of each of three rabbits and an assessment of initial pain was made.
The eyes were examined for 3 days, to assess the grade of ocular reaction.
There were no signs of ill-health in any animal during the study. Instillation into the eye caused practically no initial pain (class 1 on a 0 -5 scale). There were no corneal or iridial effects. Conjunctival effects consisted of slight redness in two animals clearing within 24 hours and slight chemosis in one animal approximately 1 hour after instillation only. There were no additional signs of irritation.
1,2,3,4-tetrachloro-hexafluorobutane is not classified as an eye irritant according to GHS criteria.
