Constituent 1
Specific details on test material used for the study:
SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 3043/V9Z

Test animals / tissue source

Species:
rabbit
Strain:
New Zealand White
Details on test animals or tissues and environmental conditions:
Animal species: rabbit / White New Zealand (SPF)
Animal supplier: Dr. K. Thomae GmbH, Biberach, Germany
Age of the animals: young adult animals
Animal identification: ear tattoo
Room temperature/ Relative humidity: the animals were housed in fully air-conditioned rooms. Central air-conditioning guaranteed a range of 20 -24 °C for temperature and of 30 -70 % for relative humidity. There were no deviations from these ranges which influenced the results of the study.
Day/night rhythm: 12 h/12 h (6.00 a.m. - 6.00 p.m./6.00 p.m. - 6.00 a.m.)
Type of cage: stainless steel wire mesh cages with grating,
No. of animals per cage: single housing
Bedding: no bedding in the cages; sawdust in the waste trays
Drinking water: about 250 ml tap water per animal per day
Diet: Kliba-Labordiaet 341, Klingentalmuehle AG, Kaiseraugst, Switzerland (about 130 g per animal per day).

Analysis of drinking water:
The drinking water is regularly assayed for chemical contaminants by the municipal authorities of Frankenthal and the Technical Services of BASF AG as well as for the presence of germs by a contract laboratory.

Analysis of feed:
The feed used in tue study was assayed for chemical and microbiological contaminants.

Test system

Vehicle:
unchanged (no vehicle)
Controls:
other: untreated eye of the same animal
Amount / concentration applied:
0.1 mL bulk volume (about 42 mg of the comminuted test substance)
Duration of treatment / exposure:
24 h
Observation period (in vivo):
8 days
Number of animals or in vitro replicates:
3
Details on study design:
REMOVAL OF TEST SUBSTANCE
- Washing: with water
- Time after start of exposure: 24 h

SCORING SYSTEM:
According to OECD guideline 405
