Materials and methods

Principles of method if other than guideline:
Eye injury in rabbits was recorded in a 10-grade ordinal series and was based upon the degree of corneal necrosis that resulted from instillation of various volumes and concentrations of a chemical. Grade 1 indicates at most a very small area of necrosis resultig from 0.5 mL of undiluted chemical in the eye. Grade 5 indicates a so-called severe burn from 0.005 mL, and Grade 10 indicates a severe burn from 0.5 mL of a 1% solution in water or propylene glycol.

Irritant / corrosive response data:
Corneal injury in rabbits Grade 8 (= excess of 5% solution gives injury of up to 5.0 points (15% gives over 5.0); see Carpenter, C.P. & Smyth, H.F.: Chemical Burns of the Rabbit Cornea. Am. J. Ophthal. 29: 1363 (Nov. 1946)).

Applicant's summary and conclusion

Interpretation of results:
study cannot be used for classification
Conclusions:
A corneal injury of Grade 8 was recorded, indicating severe, irreversible damage to rabbit's eye under the tested conditions.
Executive summary:

Eye injury in rabbits was recorded in a 10-grade ordinal series and was based upon the degree of corneal necrosis that resulted from instillation of various volumes and concentrations of a chemical. Grade 1 indicates at most a very small area of necrosis resultig from 0.5 mL of undiluted chemical in the eye. Grade 5 indicates a so-called severe burn from 0.005 mL, and Grade 10 indicates a severe burn from 0.5 mL of a 1% solution in water or propylene glycol. Under the conditions of this study, corneal injury of Grade 8 (= excess of 5% solution gives injury of up to 5.0 points (15% gives over 5.0); see Carpenter, C.P. & Smyth, H.F.: Chemical Burns of the Rabbit Cornea. Am. J. Ophthal. 29: 1363 (Nov. 1946)) was recorded, indicating severe eye damage.
