Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: right eye for control
- Amount / concentration applied:
- Solid: 0.1 g / animal (left eye only)
- Duration of treatment / exposure:
- one second
- Observation period (in vivo):
- 1, 24, 48, 72 h after administration
- Number of animals or in vitro replicates:
- 2 females and 1 male
- Details on study design:
- The eyes of the animals were examined for intactness once, one day prior to test article administration.
Only those animals with no signs of ocular injury or irritation were used on the test.
At treatment, 0.1 g of the test article (undiluted) was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of the test article. The right eye remained untreated and served as the reference control.
In cases of equivocal results when comparing the treated and untreated eyes, the illustrated guide from the Consumer Product Safety Commission Washington, C. 20207 was used for additional control purposes (Washington, 1977).
The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion
Any findings ascertained during examination were recorded and the numerical irritation scores were assigned thereafter based upon the severity of the individual findings. Therefore, the description of observed findings may differ slightly from the respective numerical irritation scores.

- PATHOLOGY
Necropsy
No necropsy was performed on the animals euthanized at termination of observation.
All rabbits were euthanized by an intravenous injection of NARCOREN (Rhone Merieux GmbH, D-88471 Laupheim) into the ear vein at a dose of at least 1.0 ml /kg body weight (equivalent to 160 mg sodium pentobarbitone/kg body weight) and discarded.
Any other information on results incl. tables
VIABILITY / MORTALITY AND CLINICAL SIGNS
No clinical signs of systemic toxicity were observed in the animals during the test and observation period, and no mortality occurred.
IRRITATION
PRIMID QM 1260 showed a primary irritation score of 0.00,when applied to the conjunctival sac of the rabbit eye.
COLORATION
No staining of the cornea, sclera or conjunctivae by the test article was observed.
CORROSION
No corrosion of the cornea was observed at any of the reading times.
BODY WEIGHTS
The body weight of the animals was within the normal range of variability.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- No test-related response was observed in the study and thus, test substance is a non-irritant for eyes of rabbits.
- Executive summary:
The primary irritation potential of the test article was investigated by instillation of 0.1 g into one eye of each of three young adult New Zealand rabbits. The treated eyes were not rinsed after application. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test article application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion. The primary irritation score was calculated by totaling the individual cumulative scores at 24, 48 and 72 hours and then dividing the resulting total by the number of figures. The primary irritation score was 0.00 (max. 13). No staining of the cornea, sclera or conjunctivae of the treated eyes by the test article was observed. No corrosion was observed at any of the measuring intervals. Based on the criteria of CLP (Regulation EC No. 1272/2008), test substance is not to be classified for eye irritation.
