Description of key information
Skin irritation potential of the substance BMS 233101-01 was tested according to EU Test Method B4, Directive 92/69/EEC and OECD Guideline 404. 500 mg of the test substance were diluted in distilled water and applied semi-occlusively on 3 New Zealand White rabbits. The test material produced a primary irritation index of 0.0 (according to the Draize classification scheme) and no corrosive effects were noted. Therefore, it does not meet the criteria for classification as irritant or corrosive according to the CLP Regulation.
The test substance was found to be mildly and/or transiently irritating to eyes with a IVIS value of <3 in a BCOP study however this was insufficient for classification. Potential of the substance BMS 233101-01 for causing eye damage or irritation was further tested according to EU Test Method B5, Directive 92/69/EEC and OECD Guideline 405. The test substance was applied to 3 New Zealand White rabbits. Mild, transient irritation was observed. Iridial inflammation was noted in one treated eye at the 1-hour observation. No other iridial effects were noted. Moderate conjunctival irritation was noted at the 1-hour observation with minimal conjunctival irritation apparent at the 24-hour observation. All treated eyes appeared normal at the 48-hour observation. No corneal alterations were observed. As a result, the substance is not classified for causing eye irritation or eye damage.

- Details on test animals or tissues and environmental conditions:
- Three New Zealand White rabbits, supplied by David Percival Ltd, Moston, Sandbach, Cheshire, UK, were used. At the start of the study the animals weighed 2.79 to 3.15 kg and were twelve to sixteen weeks old. After a minimum acclimatisation period of five days each animal was given a number unique within the study which was written with a black indelible marker-pen on the inner surface of the ear and on the cage label.
The animals were individually housed in suspended metal cages. Free access to mains drinking water and food {STANRAB SQC Rabbit Diet, Special Diets
Services Ltd, Witham, Essex, UK) was allowed throughout the study.
The animal room was maintained at a temperature of 17 to 21 'C and relative humidity of 48 to 65%. The rate of air exchange was approximately fifteen
changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light and twelve hours darkness. - Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent no treatment
- Amount / concentration applied:
- 0.1 ml of the test material, which was found to weigh approximately 49 mg
- Observation period (in vivo):
- 1 hour and 24, 48 and 72 hours following treatment
- Number of animals or in vitro replicates:

- Details on study design:
- One rabbit was initially treated. A volume of 0.1 ml of the test material, which was found to weigh approximately 49 mg {as measured by gently compacting the required volume into an adapted syringe) was placed into the conjunctiva! sac of the right eye, formed by gently pulling the lower lid away from the eyeball. The upper and lower eyelids were held together for about one second immediately after application, to prevent loss of the test material, and then released. The left eye remained untreated and was used for control purposes. Immediately after administration of the test material, an assessment of the initial pain reaction was made.

- SELECTION AND PREPARATION OF CORNEAS
The isolated corneas were then stored in a petri dish containing HBSS until they were mounted in a corneal holder. The corneas were mounted in the holders with the endothelial side against the O-ring of the posterior half of the holder. The anterior half of the holder was then positioned on top of the cornea and the screws were tightened. Starting with the posterior compartment, the two compartments of the corneal holder were then filled with Minimum Essential Medium Eagle (MEM) without phenol red, with 1 % fetal bovine serum (complete MEM). The corneal holders were incubated at 32 ± 10C for a minimum of one hour.
QUALITY CHECK OF THE ISOLATED CORNEAS
The eyes were grossly examined for damage and those exhibiting defects were discarded. The tissue surrounding the eyeball was carefully pulled away and the cornea was excised such that a 2 to 3 mm rim of sclera was present around the cornea

Additional information
Justification for classification or non-classification
The test material produced a primary irritation index of 0.0 (according to the Draize classification scheme) and no corrosive effects were noted. Therefore, it does not meet the criteria for classification as irritant or corrosive according to the CLP Regulation.
Mild, transient irritation was observed, but it was not sufficient for classification according to CLP.
