- Details on study design:
- 0.1ml of the test article was placed in the left eye of the rabbit by gently pulling the lower lid away from the eyeball to form a cup into which the article was dropped. The lids were then gently held together for 1 second. The eye was examined and the grade of ocular reaction was recorded 1 and 24 hours later. After the 24 hour reading, Fluorescein was instilled. After rinsing with 20ml 0.9% sodium chloride solution the eye was examined again using UV light to detect possible corneal damage. The eye was also examined 48 and 72 hours as well as 7 and 14 days after treatment. Because of the corneal damage observed at the 24 hour examination, fluorescein was also used at subsequent examinations.

The eye irritant effect of TMP oxetane was investigated in rabbit eye. One albino rabbit was exposed to 0.1ml of the test material in the left eye. The eye was examined and the changes were graded according to a numerical scale 1, 24, 48 and 72 hours as well as 7 and 14 days after dosing. Marked signs of corneal and conjunctival irritation were observed in the rabbit 1 hour to 7 days after termination of exposure. On day 14, no abnormalities were observed in the rabbit. The following mean values based on the 24, 48 and 72 hour readings are 1.0 for corneal opacity, 0 for iris lesions, 3.0 for conjunctiva oedema and 3.0 for conjunctival redness. Under the conditions of this study, TMP oxetane was found to be irritating to the eyes and meets the criteria for classification as an eye irritant.

Additional information
Skin irritation/corrosion
The skin irritation potential of 3-ethyloxetane-3-methanol was investigated in rabbits in a GLP study conducted according to OECD Test Guideline 404 (Kaaber, 1998a). In the study, three rabbits were exposed to the test substance, TMP oxetane, at two skin sites on the back, under an occluded dressing. After 4 hours of exposure, tape and patches were removed and the treated areas were washed with lukewarm water to remove the test substance. Skin reactions were observed 1, 24, 48 and 72 hours after the termination of exposure. No skin reactions or only very slight skin reactions were observed in all three animals from 1 to 72 hours after the termination of exposure. Mean scores of 0 were reported for erythema and oedema respectively. Under the conditions of the study, 3-ethyloxetane-3-methanol was not found to be irritating to skin.
Eye irritation
The eye irritation potential of 3-ethyloxetane-3-methanol was investigated in rabbits in a GLP study conducted according to OECD Test Guideline 405 (Kaaber, 1998b). In the study, one albino rabbit was exposed to 0.1 ml of the test material, TMP oxetane in the left eye. The eye was examined and any changes were graded according to a numerical scale, 1, 24, 48 and 72 hours as well as 7 and 14 days after dosing. Marked signs of corneal and conjuctival irritation were observed in the treated eye of the rabbit 1 hour to 7 days after termination of exposure. No abnormalities were observed on the 14 th day after treatment. The following mean scores were obtained based on 24, 48 and 72 hour readings: 1.0 for corneal opacity; 0 to iris lesions, 3.0 for conjunctiva oedema and 3.0 for conjuctival redness. It was concluded that 3-ethyloxetane-3-methanol is irritating to the eyes and the substance meets the criteria for classification as an eye irritant.
Justification for classification or non-classification
Based on the results of skin and eye irritation, TMPO is classified as an eye irritant (Cat 2) according to the CLP Regulation. Classification for skin irritation is not required.
