ENVIRONMENTAL CONDITIONS
Controlled environment, environmental conditions were:
- Ventilation, air changes per hour: 15-20
- Temperature (°C): 19.7 to 27.1°C
- Relative Humidity (%): 32 to 83%
- Photoperiod (artificial lighting): 12 hrs day / 12 hrs night
Relative humidity and temperature at times slightly exceeding the upper target limits of 70% and 23°C, respectively were not considered to have compromised the integrity or validity of the study. - Vehicle:
- unchanged (no vehicle)
- Controls:
- not required
- Amount / concentration applied:
- 0.1 mL of the undiluted wax-like test material was administered into the conjunctival sac of one eye per rabbit (left eye). The contralateral eye (right eye) remained untreated to serve as a control.
- Duration of treatment / exposure:
- Residual test material was seen in the treated eyes. Therefore, the eyes were rinsed with physiological saline at 1 hour after test material instillation.
- Observation period (in vivo):
- 21 days
- Number of animals or in vitro replicates:
- 3 adult male rabbits
- Details on study design:
- EYE EVALUATION:
Within 2.5 hours before treatment start both eyes of each animal were investigated to ensure that there were no pre-existing corneal damage, eye irritation or ocular defects.
One animal was initially treated and, in the absence of a severe effect at 1 hour post instillation, the remaining two animals were committed to the study.
Eyes were evaluated in all animals at approximately 1, 24, 48 & 72 hours and 7, 14 & 21 days after test material 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.

- Irritant / corrosive response data:
- Iridic lesions were not evident throughout the study. Corneal lesions (opacity grade 1, except for grade 2 in one animal at 1 h after test material instillation) were seen in all animals until 72 hours after test material instillation and had entirely disappeared in all animals by 7 days after instillation. In each animal, the area of cornea affected was scored grade 4 to 0. Conjunctival redness grade 2, chemosis grade 3 and discharge grade 3, were seen in all animals at 1 h after instillation, therafter gradually decreasing in severity and incidence. By 7 days after instillation chemosis and discharge had fully disappeared in all animals and by 21 days after instillation conjunctival redness had fully disappeared. Control eyes were without ocular findings throughout the observation period.
- Other effects:
- Observation of the animals for defined behavioural criteria led to the conclusion that instillation of the test material induced slight initial pain (grade 2). Any other signs of systemic toxicity or ill health were not evident and bodyweight was unaffected by treatment with the test material.
- Interpretation of results:
- other: irritating
- Conclusions:
- The substance is irritating to eyes. All findings noted were fully reversible.

Additional information
Justification for classification or non-classification
The reversible skin irritation observed in the in vivo skin irritation study necessitates classification of WS400102 as "category 2 irritant" [REGULATION (EC) 1272/2008].
The reversible effects observed in the in vivo eye irritation study necessitate classification of WS400102 as “Category 2 (reversible effects on the eye)" [REGULATION (EC) 1272/2008].
