EC number: 269-057-9 | CAS number: 68186-95-8 An inorganic pigment that is the reaction product of high temperature calcination in which zirconium (IV) oxide, silicon oxide, and vanadium (IV) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of zircon. Its composition may include any one or a combination of the modifiers alkali or alkaline earth halides.

Test animals
- Species:
- rabbit
- Strain:
- Vienna White
- Details on test animals or test system and environmental conditions:
- TEST ANIMALS
- Weight at study initiation: male: 2.81 kg; females: 2.53 kg and 2.72 kg
- Housing: cage made of stainless steel with wire mesh walk floors, floor area: 40 cm X 51 cm; no bedding in the cages; sawdust in the waste trays; rabbits were housed singly.
- Diet (about 130 g per animal per day): Kliba 341, 4 mm; Firma Klingentalmuehle AG, CH-4303 Kaiseraugst, Switzerland
- Water (about 250 mL per animal per day): tap water
- Acclimation period: at least 8 days before the beginning of the study; same housing conditions as during the study
ENVIRONMENTAL CONDITIONS - animals were housed in fully air-conditioned rooms.
- Temperature: 20 - 24 °C
- Relative humidity: 30 - 70 %
- Photoperiod (hrs dark / hrs light): 12/12
No further information on the test animals was stated.
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- other: clipped
- Vehicle:
- water
- Controls:
- no
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 0.5 g of the unchanged test substance
No further information on the amount/concentration applied was stated. - Duration of treatment / exposure:
- 4 hours
- Observation period:
- 30 - 60 minutes after removal of the test patches and 24, 48 and 72 hours after the beginning of the application
- Number of animals:
- 1 male / 2 females
- Details on study design:
- TEST SITE
- Area of exposure: at least 15 hours before the beginning of the study the upper third of the back or flanks were clipped. The application area was 2.5 cm x 2.5 cm. The test patch (2.5 cm x 2.5 cm) was covered with a dose of the unchanged test substance and has been moistened with aqua bidest.. Because of the natural moisture of the skin, distilled water was used so that the test has been carried out under as physiological conditions as possible.
- Type of wrap if used: test patches were secured in position with a porous dressing (four layers of absorbent gauze + porous bandage).
REMOVAL OF TEST SUBSTANCE
- Time after start of exposure: at the end of the exposure period
- Washing: with lutrol and lutrol/water (1:1)
SCORING SYSTEM: according to a modified Draize scale
Evaluation of erythema and oedema:
0 = none
1 = very slight
2 = well-defined
3 = moderate to severe
4 = severe to very severe
OBSERVATIONS:
Shortly before application of the test substance the weight of the rabbits was determined. Symptoms were recorded.
No further information on the study design was stated.
