- TEST SITE PREPARATION AND ADMINISTRATION
On the day before treatment, hair was removed with clippers from the dorsolumbar region of each animal. The neat test substance was administered under a 2-ply 25 mm x 25 mm porous gauze pad secured with 'blenderm' surgical tape to intact skin sites. For exposures of one hour or more each treatment site was covered additionally with cotton wool and "Tubigrip" elasticated bandage dressing for the duration of the exposure period.
On each animal an additional site was similarly treated with the exception of test substance and acted as a control.
REMOVAL OF TEST MATERIAL
At the end of the exposure period, the semi-occlusive dressing and gauze pad were removed and the treatment site was washed with lukewarm water (30-40°C) to remove any residual test substance. The treated area was blotted dry with absorbent paper.
SKIN EVALUATION:
The treated skin patches were evaluated immediately after patch removal (for 3 minute and 1 hour exposures) and at 1, 24, 48 and 72 h afterwards, whereby only the data for the 4 hour exposures were reported. This was followed by daily evaluation of the skin reactions until Day 8 (i.e. 7 days post patch removal) in animals # 2 and 3 and by evaluation in all three animals on Day 8. The scoring system for the grading of skin reactions is listed in Table 1 (next field below). - Irritation parameter:

Edema were not evident throughout the 7 days after patch removal. The test sites of two animals were stained brown by the test substance throughout the observation period; this staining did not interfere with the assessment of irritation.

ENVIRONMENTAL CONDITIONS
Air conditioned animal room set at:
- Temperature (°C): 18 ± 2°C
- Relative Humidity (%): 40 to 70%
- Photoperiod: 12 hrs artificial light per 24 hrs
- Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.1 ml of undiluted liquid test substance was administered into the conjunctival sac of one eye per rabbit (right eye). The contralateral eye (left eye) remained untreated to serve as a control.
- Duration of treatment / exposure:
- There was no mentioning in the report that eyes were rinsed after treatment. Consequently the treatment/exposure period was equivalent to the entire observation period following instillation or lasted until removal of the test material by physiological mechanisms, whichever happened sooner.
- Observation period (in vivo):
- 8 days in one animal (sentinel) and 72 hours in the other two animals
- Number of animals or in vitro replicates:
- 3 adult female rabbits
- Details on study design:
- EYE EVALUATION:
Before treatment start both eyes of each animal were investigated to ensure that there was no pre-existing corneal damage, iridial inflammation or conjunctival irritation.
One animal (the sentinel) was initially treated and in the absence of a severe effect the remaining two animals were committed to the study.
Eyes were evaluated in all animals at approximately 1, 24, 48 and 72 hours after test substance instillation adopting the numerical scoring system listed in Table 1 in the field below. Grades attained at 24, 48 and 72 hours after instillation were included in the mean gradings of ocular lesions and used for evaluation of the necessity of eye irritation/corrosion classification. In addition, eyes of the sentinel animal were checked eight days after treatment for possible delayed effects.

Conjunctival redness grade 1 was seen in all treated eyes at 1, 24 and/or 48 hours after instillation having completely disappeared in one animal by 48 hours and in the other two animals by 72 hours after instillation. In addition, chemosis grade 1 was seen in one animal at 24 and 48 hours post instillation and had completely disappeared by 72 hours after instillation. Throughout the study no other signs of ocular irritation were evident.
- Other effects:
- Observation of the animals for defined behavioural criteria led to the conclusion that instillation of the test substance induced no or a slight initial pain response. Any other signs, of systemic toxicity or ill health were not evident.

Additional information
Justification for classification or non-classification
In view of the absence of any relevant effects during the skin and eye irritation studies with WS400152, the attained results do not necessitate any classification and labelling regarding skin or eye irritation according to EU classification rules [REGULATION (EC) 1272/2008].
