TOOL USED TO ASSESS SCORE: hand-slit lamp / fluorescein
The test substance was placed in the conjunctival sac of the right 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 in order to prevent loss of the material. The eyes were examined ophthalmoscopically with a slit lamp prior to the administration and 1, 24, 48, and 72 hours after the administration. 24 h after administration the eyes were treated additionally with fluorescein and examined. - Irritation parameter:

- Irritant / corrosive response data:
- Corneal opacity was observed at 1 h in all 3 animals (grade 1: 2/3; grade 2: 1/3). Opacity increased after 24 and 48 h (grade 3: 2/3; grade 2: 1/3). From 72 h until 21 days opacity (grade 2) was observed in all animals. Iris evaluation was not possible at 24 and 48 h in all animals. At 72 h iris scores of 1 and 2 were observed in one animal each (no evaluation possible in the third animal). From day 4 until day 21 the iris scores persisted (grade 1) in all animals. Redness was observed after 1 h and was fully reversible within 8 and 9 days, respectively. Chemosis was observed after 1 h (grade 3) and was fully reversible within 6 days. In addition, hair loss around the eyes was observed in 2 animals from 24 h until day 11 and in one animal from 48 h until day 12. White deposits, (probably pus) in the conjunctival sac were observed in 2/3 animals 72 h to 6 days after instillation, and in 1/3 animals from 24 h to 8 days after instillation. Enlargement of the bulbus due to accumulation of fluid below the cornea was noted in 2/3 animals from day 8 to 21 and in 1/3 animals from day 7 to 21. 1/3 animals showed oedematous cornea 14 to 17 days after instillation.
- Other effects:
- No systemic intolerance reactions were observed.
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- A reliable study performed in accordance with OECD 405 and GLP found the test material to be corrosive to the eye of rabbits. Mean values (over 24, 48, 72 h) for cornea score were 2, 2.66, and 2.66 in animal 1, 2, and 3, respectively. Mean values for redness (over 24, 48, 72 h) was 1 in all animals. Mean values (over 24, 48, 72 h) for chemosis score were 1.33 in all animals. Iris evaluation was not possible up to 48 in all animals. Effects on cornea (grade 2) and iris (grade 1) were not reversible within 21 days.

Additional information
A skin irritation test is available with N-[3-(triethoxysilyl)propyl]ethylenediamine (CAS 5089-72-5), which was performed in Himalayan rabbits according to OECD 404 and in compliance with GLP (LPT, 2002a). Pure test substance (0.5 ml) was applied to a 6 cm² application site (shaved) for 4 h under semi-occlusive conditions. No residual test substance had to be removed. Sixty minutes and 24, 48, 72 h after patch removal the application site was examined. Erythema grade 1 (2/3 animals) and 2 (1/3 animals) were observed 60 min after patch removal. Very slight edema reactions (grade 1) were observed in all 3 animals 60 min after removal of the patch but were fully reversible within 24 h (2/3) and 72 h (1/3), respectively. Skin induration was observed in all 3 animals from day 4 until the end of the study. A dark brown discoloured application area was observed in one animal from 4 days to the end of the study. Peeling of the application site was observed in 3/3 animals after 9 days and persisted until the end of the study. Laceration of skin induration was observed in 1/3 animals at day 6, 7, and 9. No systemic effects were reported. In summary, the mean erythema scores over 24, 48, and 72 h were 2, 1, and 1 for animals #1 -3, and the mean edema scores over 24, 48, and 72 h were 0.66, 0, and 0 for animals #1 -3, respectively. Thus, N-[3-(triethoxysilyl)propyl]ethylenediamine is concluded to be irritating to the skin under the conditions of the test.
Eye irritation
An eye irritation test is available with N-[3-(triethoxysilyl)propyl]ethylenediamine (CAS 5089-72-5), which was performed in Himalayan rabbits according to OECD 405 and in compliance with GLP (LPT, 2002b). Pure test substance (0.1 ml) was placed in the conjunctival sac of the right 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 in order to prevent loss of the material. The eyes were examined ophthalmoscopically with a slit lamp prior to the administration and 1, 24, 48, and 72 hours after the administration. 24 h after administration the eyes were treated additionally with fluorescein and examined. Corneal opacity was observed at 1 h in all 3 animals (grade 1: 2/3; grade 2: 1/3). Opacity increased after 24 and 48 h (grade 3: 2/3; grade 2: 1/3). From 72 h until 21 days opacity (grade 2) was observed in all animals. Iris evaluation was not possible at 24 and 48 h in all animals. At 72 h iris scores of 1 and 2 were observed in one animal each (no evaluation possible in the third animal). From day 4 until day 21 the iris scores persisted (grade 1) in all animals. Redness was observed after 1 h and was fully reversible within 8 and 9 days, respectively. Chemosis was observed after 1 h (grade 3) and was fully reversible within 6 days. In addition, hair loss around the eyes was observed in 2 animals from 24 h until day 11 and in one animal from 48 h until day 12. White deposits, (probably pus) in the conjunctival sac were observed in 2/3 animals 72 h to 6 days after instillation, and in 1/3 animals from 24 h to 8 days after instillation. Enlargement of the bulbus due to accumulation of fluid below the cornea was noted in 2/3 animals from day 8 to 21 and in 1/3 animals from day 7 to 21. 1/3 animals showed edematous cornea 14 to 17 days after instillation. Mean values (over 24, 48, 72 h) for cornea score were 2, 2.66, and 2.66 in animal 1, 2, and 3, respectively. Mean values for redness (over 24, 48, 72 h) was 1 in all animals. Mean values (over 24, 48, 72 h) for chemosis score were 1.33 in all animals. In conclusion, N-[3-(triethoxysilyl)propyl]ethylenediamine was corrosive to the eye under the conditions of the test
Justification for classification or non-classification
The available data on skin irritation/corrosion of the test substance meet the criteria for classification as Category 2 (Causes skin irritation (H315)) according to Regulation (EC) No. 1272/2008.. Basis for the classification was the fact that inflammation, indicated by the occurrence of erythema (grade 1+2), induration, and peeling of the skin, were observed in all 3 animals at the end of the 14-day observation period.
The available data on eye irritation of the test substance meet the criteria for classification as Category 1 (Causes serious eye damage (H318)) according to Regulation (EC) Np. 1272/2008. Basis for the classification was the fact that effects on cornea (grade 2) and iris (grade 1) were observed in all 3 animals at the end of the 21-day observation period.
