- Irritant / corrosive response data:
- No effects were observed in body weight gain or food consumption of the rabbits. Eye irritation was noted in group one animals with unwashed eyes after instillation. No eye irritation was noted in group two animals with washed eyes following treatment (30 seconds after instillation).
Group 1 (unwashed):
Slight to moderate swelling and iritis and slight damage to cornea were noted at 24, 48 and 72 hours. All eyes appeared normal by day 14 of observation period.
Group 2 (washed after 30 seconds):
Slight to severe pain after instillation of the test material. At 1 and 24 hours, slight to moderate conjunctival redness with swelling in all rabbits and slight corneal injury was observed in one animal at 24 hours. At 48 hours observation, slight redness with swelling was seen in 2/3 rabbits and one animal still showed slight corneal injury and slight iritis. All treated eyes appeared normal by day 7 of the observation period. - Other effects:
- Not specified
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Conclusions:
- In the eye irritation study, conducted according to OECD Test Guideline 405 and in compliance with GLP, the test material, trimethoxy(methyl)silane and its reaction products with [3-(2,3-epoxypropoxy)propyl]trimethoxysilane and 3-(trimethoxysilyl)propylamine, was reported to be irritating to eyes.
