- Executive summary:
In a dermal irritation study according to OECD TG 404 the test material was applied under semiocclusive conditions for 4 hours to the shaved skin of 3 rabbits. Skin irritation was assessed after 1, 24, 48 and 72 hours using the Draize scale. Erythema (grade 1) and oedema (grade 1 - 2) was observed in all animals 24 hours to days 7 - 10 after treatment. In addition, induration of the skin, laceration and peeling of the skin was noted in all animals. The effects partly lasted up to day 11 after patch removal. The test material should therefore be regarded as irritating to the skin of rabbits. No systemic intolerance reactions were observed.
According to classification criteria Butanoylanilin is an irritant to the skin.

- Under the present test conditions, a single application of 100 mg 4-Chlor-3-(trifluormethyl)phenylisocyanat per animal into the conjunctival sac of the right eye of three rabbits caused the following effects:
Corneal opacity (grade 1) was observed in all animals 1 hour to 72 hours after instillation, in animal no. 1 until 9 days, in animal no. 2 until 21 days after instillation. The fluorescein test performed after 24 hours revealed corneal staining in animal nos. 1 and 2 (3/4 of the surface) and animal no. 3 (1/2 of the surface). The fluorescein test performed after 7 days revealed corneal staining in animal nos. 1 and 2 (1/4 of the surface). The fluorescein test performed after 14 days revealed corneal staining in animal no. 2 (1/4 of the surface).
Irritation of the iris (grade 1) was noted in all animals 1 hour to 72 hours after instillation, in animal nos. 1 and 2 until 9 days after instillation.
Conjunctival redness (grade 1) was observed in all animals 1 hour to 48 hours after instillation, in animal nos. 1 and 2 until 15 days after instillation.
Conjunctival chemosis (grade 1) was observed in all animals hour to 24 hours after instillation, in animal no. 1 until 72 hours after instillation. In addition, white deposits in the conjunctival sac were observed in all animals 48 to 72 hours, in animal no. 1 until 4 days, in animal no. 2 until 5 days after instillation. Loss of hair on upper eyelid was observed in animal no. one 6 to 8 days, in animal no. two 6 to 9 days after instillation. Loss of hair on upper and lower eyelid was noted in animal no. one 9 to 21 days, in animal no. two 10 to 21 days after instillation. Secretion of the treated eye was observed in animal no. one 11 to 18 days after instillation. - Other effects:
- No systemic intolerance reactions were observed.
- Interpretation of results:
- Category 1 (irreversible effects on the eye)
- Remarks:
- Migrated information
- Executive summary:
In an eye irritation study according to OECD TG 405 the test substance was instilled into the conjunctival sac of one eye of 3 male rabbits each. Eye irritation was assessed 1, 24, 48 and 72 hours and 4 to 21 days after instillation using the Draize scale. In this study slight irritation was seen as corneal opacity (grade 1), effects on iris (grade 1), conjunctional redness (grade 1) and conjunctional chemosis (grade 1). The cornea effects appeared to be not reversible within the 21 days observation period in one animal. Loss of hair at the upper and lower eye lid and white deposits in the conjunctival sac became obvious. No systemic intolerance reactions were observed.
According to classification criteria 4-Chlor-3-(trifluormethyl)-phenylisocyanat causes serious damage to rabbit's eyes.

Additional information
Skin irritation:
In a dermal irritation study according to OECD TG 404 the test material was applied under semiocclusive conditions for 4 hours to the shaved skin of 3 rabbits. Skin irritation was assessed after 1, 24, 48 and 72 hours using the Draize scale. Erythema (grade 1) and oedema (grade 1 - 2) was observed in all animals 24 hours to days 7 - 10 after treatment. In addition, induration of the skin, laceration and peeling of the skin was noted in all animals. The effects partly lasted up to day 11 after patch removal. The test material should therefore be regarded as irritating to the skin of rabbits. No systemic intolerance reactions were observed.
Eye irritation:
In an eye irritation study according to OECD TG 405 the test substance was instilled into the conjunctival sac of one eye of 3 male rabbits each. Eye irritation was assessed 1, 24, 48 and 72 hours and 4 to 21 days after instillation using the Draize scale. In this study slight irritation was seen as corneal opacity (grade 1), effects on iris (grade 1), conjunctional redness (grade 1) and conjunctional chemosis (grade 1). The cornea effects appeared to be not reversible within the 21 days observation period in one animal. Loss of hair at the upper and lower eye lid and white deposits in the conjunctival sac became obvious. No systemic intolerance reactions were observed.
According to classification criteria 4-Chlor-3-(trifluormethyl)-phenylisocyanat causes serious damage to rabbit's eyes.
