Remarks:
During the MTT assay isopropanol / 2 N HCl 49:1 (v/v) should have been used as extractant solution. Due to inattention isopropanol without HCl was used as extractant solution. Due to Harlan CCR’s experimental experience concerning formazan salt extraction with and without acidifying of isopropanol, and due to the long extraction period of nearly three days, the risk of inadequate extraction is minimized. Therefore, the described deviation did not have a detrimental impact on the outcome of the study.
Justification for type of information:
Zircon, cadmium yellow is a zircon-type oxide/pigment with the main structural element ZrSiO4 (Zr in an dodecahedral O environment) which forms a strong and inert matrix. Zr and Si are the main components with percentages of ~46% w/w and 15% w/w respectively. The amount of Cd as component is about 2% w/w.

The read-across substance Silicic acid, zirconium salt, cadmium pigment encapsulated is a zircon-type pigment as well with an identical crystallographic structure and a very similar composition. Zr content is ~46% w/w and the Si content is ca. 14% w/w. Cd is present in about 4.7% w/w. Minor amounts of Se and S (1.53 and 1.04% w/w, respectively) are present as well.

Besides the obvious structural analogy the solubility of both pigments in aqueous and physilogical media are as follows (determination of Zr and Cd):

Solubility of Cd from the pigment Zircon, cadmium yellow in physiological media was in a range of 0.180 µg/L (PBS) and 0.398 µg/L (ALF) after 2 hours. After 24 hours a dissolution range from 0.140 µg/L (GMB) - 0.722 µg/L (GST) was measured.

Solubility of Zr from the pigment Zircon, cadmium yellow in physiological media was in a range of below LOD and 0.812 µg/L (ALF) after 2 hours. After 24 hours a dissolution range from below LOD (ASW) - 1.44 µg/L (ALF) was measured.

The read-across substance Silicic acid, zirconium salt, cadmium pigment encapsulated afforded after 2 hours a solubility for the element Cd in range of 0.07 µg/L (GMB) 2.58 µg/L (GST) and after 24 hours a solubility of 0.07 µg/L (GMB) to 6.13 µg/L (GST).

Solubility of Zr from the pigment Silicic acid, zirconium salt, cadmium pigment encapsulated in physiological media was in a range of below LOD and 0.52 µg/L (ALF) after 2 hours. After 24 hours a dissolution range from below LOD - 1.25 µg/L (ALF) was measured.

T/D testing of the pigment Zircon, cadmium yellow afforded the following solubility at 1mg loading after 28 days:
Cadmium: below LOD (<0.0048) and 0.2077 ± 0.0993μg/L at pH 8 and pH 6, respectively
Zirconium:
T/D testing of the read-across substance Silicic acid, zirconium salt, cadmium pigment encapsulated afforded the following solubility at 1mg loading after 28 days:
Cadmium: 0.34 ± 0.09 μg/L and 0.86 ± 0.39 μg/L at pH 8 and pH 6, respectively
Zirconium:
In sum, the two zircon type pigments are structurally identical with very similar composition and both show a very low solubility in different artificial and aqueous media. In fact, the read-across substance Silicic acid, zirconium salt, cadmium pigment encapsulated shows slightly higher dissolution and bioaccessibility without showing any signs of systemic or local toxicity in various studies (acute inhalation, skin/eye irritation, sensitisation). No toxicity on algae, fish and invertebrates could be observed in respective studies.
Hence, read-across to Silicic acid, zirconium salt, cadmium pigment encapsulated is fully justified.

Details on test system:
RECONSTRUCTED HUMAN EPIDERMIS (RHE) TISSUE
- Model used: EpiSkin™ tissues (purchased from SkinEthic Laboratories)
- Tissue batch number: 12-EKIN-013
- Experiation date: 2012-04-02
- Delivery date: 2012-03-28
- Date of initiation of testing:2012-03-28

TEMPERATURE USED FOR TEST SYSTEM
- Temperature used during treatment / exposure: 37 ± 1.5 °C
- Temperature of post-treatment incubation: 37 ± 1.5 °C

REMOVAL OF TEST MATERIAL AND CONTROLS
After the end of the treatment interval the inserts were removed from the plate and the tissues were rinsed with PBS to remove any residual test material. Then the inserts were placed in the plates with maintenance medium. The tissues were incubated for about 42 hours at 37 ± 1.5 °C, 5 ± 0.5% CO2.

MTT DYE USED TO MEASURE TISSUE VIABILITY AFTER TREATMENT / EXPOSURE
- MTT concentration: 0.3 mg/mL
- Incubation time with MTT: 3 hours
- Extraction of formazan: after the incubation period, MTT solution was aspirated from the wells and the wells were rinsed with PBS. Tissue samples were cut out of the inserts with a biopsy punch and transferred into plastic vials. The tissue samples were immersed into extractant solution by pipetting 0.5 mL extractant solution (isopropanol) into each vial. The tissue samples were completely covered by isopropanol. The vials were sealed to inhibit isopropanol evaporation. The formazan salt was extracted for about 69 hours in the refrigerator.
Per each tissue sample 2 x 200 μL aliquots of the formazan blue solution were transferred into a 96-well flat bottom microtiter plate. Optical density (OD) was read with a spectrophotometer. Mean values were calculated from the 2 wells per tissue sample.
- Spectrophotometer: microplate reader (Versamax® Molecular Devices)
- Wavelength: 570 nm
- Filter: 1 nm

TEST FOR DIRECT MTT REDUCTION
To test for the ability of the test item to directly reduce MTT approx. 10 mg of the test item were added to 1 mL of MTT solution and the mixture was incubated in the dark at room temperature for 60 minutes. Untreated MTT medium was used as control. If the MTT solution colour turned blue/purple, the test item was persumed to have reduced the MTT.

FUNCTIONAL MODEL CONDITIONS WITH REFERENCE TO HISTORICAL DATA
- Barrier function: tissues passed analysis for tissue functionality
- Morphology: well-differentiated epidermis consisting of a basal layer, several spinous and granular layers and a thick stratum corneum.
- Contamination: absence of bacteria, fungus and mycoplasma as well as absence of HIV 1 and 2 antibodies, hepatitis C antibodies and absence of hepatitis B antigen
Please also refer to the field "Attached background material" below.

PREDICTION MODEL / DECISION CRITERIA
The mean optical density of the three negative control tissues was calculated. This value corresponds to 100% tissue viability in the current test. For each individual tissue treated with the test item or the positive control the individual relative tissue viability was calculated according to the following formula: relative viability(%) = (OD test item/ OD negative control) x 100
For the test item and the positive control the mean relative viability ± standard deviation of the three individual tissues was calculated and used for classification according to the following prediction model: if the mean relative tissue viability of three individual tissues is less than or equal to 50% of the negative control, the test item needs to be classified and labeled for its skin irritation potential: Category 2 – irritant, H315 according to Regulation (EC) No 1272/2008.

Any further lesions are listed.

TOOL USED TO ASSESS SCORE: 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 (Fluorescein SE Thilo drops (ALCON PHARMA GmbH, 79108 Freiburg, Germany) was applied to the eyes before being examined to aid evaluation of the cornea for possible lesions.

Read-across information:

Skin irritation

One reliable in vitro study described by Heppenheimer (2012) (OECD 439; GLP compliant) is considered to be reliable without restrictions. The substance was determined to be not irritating to the skin.

Eye irritation

One reliable in vivo study described by Leuschner (2012) (OECD 405; GLP compliant) is considered to be reliable without restrictions. The substance was determined to be not irritating to the eyes.

Justification for classification or non-classification

Skin irritation

The substance does not possess an skin irritating potential based on an in vitro OECD 439 (2010) test and does not require classification as skin irritating according to Regulation (EC) No 1272/2008 and its subsequent adaptations.

Eye irritation

The substance does not possess an eye irritating potential based on an in vivo OECD 405 (2002) test and does not require classification as eye irritating according to Regulation (EC) No 1272/2008 and its subsequent adaptations.
