- Details on test animals or tissues and environmental conditions:
- TEST ANIMALS
- Source: LPT Laboratory of Pharmacology and Toxicology GmbH & Co. KG, Branch Löhndorf, 24601 Löhndorf/Post Wankendorf, Germany
- Age at study initiation: Approx. 6.5 - 7.5 months
- Weight at study initiation: 2.8 kg
- Housing: For 8 hours following test item administration, the animals were kept singly in restrainers which allowed free movement of the head but prevented a complete body turn, wiping of the eyes with the paws and excluded irritation of the eye by excrements and urine. During the acclimatisation period and after the 8-hour period in restrainers, the animals were kept singly in cages with dimensions of 380 mm X 425 mm X 600 mm (manufacturer: Dipl. Ing. W. EHRET GmbH, 16352 Schönwalde, Germany).
- Diet (ad libitum): Commercial diet, ssniff® K-H V2333 (ssniff Spezialdiäten GmbH, 59494 Soest, Germany
- Water (ad libitum): tap water
- Acclimation period: at least 20 adaption days
ENVIRONMENTAL CONDITIONS
- Temperature: 20 °C +/- 3 ^C (maximum range)
- Relative humidity: 30 % - 70 % (maximum range; aim was 50 % - 60 %)
- Photoperiod (hrs dark / hrs light): 12/12
No further information on the test animals was stated.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 100 mg of the test item were administered into the conjunctival sac of the right eye. The left eye, which remained untreated, served as a control.
No further information on amount/concentration applied was stated. - Duration of treatment / exposure:
- 1 hour after administration the eyes were rinsed.
- Observation period (in vivo):
- 1, 24, 48 and 72 hours after administration
- Number of animals or in vitro replicates:
- 3 male rabbits
- Details on study design:
- REMOVAL OF TEST SUBSTANCE
- Washing: The eyes were rinsed with portions of 20 mL 0.9 % aqueous NaCl solution, each.
- Time after start of exposure: 1 hour after start of exposure
SCORING SYSTEM: Draize scoring system
TOOL USED TO ASSESS SCORE: hand-slit lamp and fluorescein
The eyes were examined ophthalmoscopically with a slit lamp prior to the administration and 1, 24, 48 and 72 hours after the administration. The eye reactions were observed and registered. 24 hours after administration, fluorescein was applied to the eyes before being examined to aid evaluation of the cornea for possible lesions.
OTHER OBSERVATIONS: Any further lesions not covered by the scoring system were recorded. Body weights of all animals was measured at the beginning of the study. Behaviour and food consumption were monitored.
No further information on study design was stated.

- Irritant / corrosive response data:
- Under the present test conditions, a single instillation of 100 mg Sodium hexahydroxoantimonate per animal into the conjunctival sac of the right eye of three rabbits caused the following changes:
Conjunctival redness was observed in all animals 1 hour after instillation. In addition, secretion was observed in all animals 1 hour after instillation.
The cornea and the irises were not affected by instillation of the test item.
The fluorescein test performed 24 hours after instillation did not reveal any changes. - Other effects:
- There were no systemic intolerance reactions.
Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- According to the EC-Commission directive 67/548/EEC and its subsequent amendments on the approximation of the laws, regulations and administrative provision relating to the classification, packaging and labelling of dangerous substances and the results obtained under the present test conditions sodium hexahydroxoantimonate was non-irritating to eyes, hence, no labelling is required.
Also, according to the EC-Regulation 1272/2008 and subsequent regulations, the test item is non-irritatng.
