The data on the individual constituents CHA/MDI/CHA (EC 406-370-3) and ODA/MDI/ODA (EC 406-690-3) for physicochemical, environmental fate, ecotoxicological and mammalian toxicological endpoints are very similar to the data available for the different compositions of the multi-constituent or represent the outer boundaries of the data on the multi-constituent. Hence, they confirm that the different compositions are expected to have similar properties for physicochemical, environmental fate, ecotoxicological and mammalian toxicological endpoints.

Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- TEST MATERIAL
- Amount applied: Approx. 63 ± 1 mg (0.1 mL)
- Duration of treatment / exposure:
- Single treatment followed by observations at 1, 24, 48 and 72 hours.
- Observation period (in vivo):
- 72 hours
- Number of animals or in vitro replicates:
- 3 females
- Details on study design:
- The test substance was instilled in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to preven loss of the the test substance. After 24 hours observation, a solution of 2% fluorescein in water (adjusted to pH 7.0) was applied to both eyes of each animal to quantitatively examine the potential for corneal injury. Any bright green stained area, indictating epithelial damage, was estimated as a percentage of the total corenal area. After fluorescein examination both eyes of animal #3 were rinsed with approx. 50 mL tap-water to remove residual test item.
SCORING SYSTEM: According to the Draize scale.
OBSERVATIONS:
- Mortality: Daily
- Clinical observations: Eyes were examined approximately 1, 24, 48, 72 hours after instillation.
- Body weights: Day 1 of application

- Irritant / corrosive response data:
- Irritation to the conjunctivae was observed in all three animals. The irritation was fully reversible within 72 hours.
Treatment of the eyes with 2% fluorescein 24 hours after test item instillation revealed no corneal epithelial damage. - Other effects:
- - Coloration: No staining of the test substance occurred.
- Mortality: No signs of systemic toxicity were observed in the animals during the test period and no mortality occurred.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of an in vivo eye irritation study in rabbits, performed according to OECD guideline 405 and GLP principles, MDI/CHA/ODA is not irritant to the eyes and is not classified for eye irritation according to GHS and CLP criteria.
