- Time after start of exposure: 15 minutes

POST INCUBATION PERIOD
- 42 hours

SCORING SYSTEM:
- After a 42 hour incubation period, determination of the cytotoxic (irritancy) effect was performed. Cytotoxicity is expressed as the reduction of mitochondrial dehydrogenase activity measured by formazan production from MTT at the end of the treatment. Cell viability was calculated for each tissue as a percentage of the mean of the negative control tissues.
Control samples:
yes, concurrent negative control
yes, concurrent positive control
Amount/concentration applied:
The test was performed on a total of 3 tissues per test item together with negative and positive controls. The skin was moistened with 5 µl Milli-Q water (Millipore Corp., Bedford, Mass., USA) to ensure close contact of the test item to the tissue and the solid test item (15.18 to 20.30 mg) was added into 12-well plates on top of the skin tissues. Three tissues were treated with 25 µl PBS (negative control) and 3 tissues with 25 µl 5% SDS (positive control) respectively. The positive control was re-spread after 7 minutes contact time.

The relative mean tissue viability obtained after 15 ± 0.5 minutes treatment with Iron trigluconic acid, trisodium salt compared to the negative control tissues was 116%. Since the mean relative tissue viability for Iron trigluconic acid, trisodium salt was above 50%, Iron trigluconic acid, trisodium salt is considered to be non-irritant.

The positive control had a mean cell viability after 15 ± 0.5 minutes exposure of 5.7%. The absolute mean OD570of the negative control tissues was within the laboratory historical control data range. The standard deviation value of the percentage viability of three tissues treated identically was ≤ 18%, indicating that the test system functioned properly.

Interpretation of results:

Conclusions:
It is concluded that the test substance is non-irritant in the in vitro skin irritation test.

Executive summary:

The objective of this study was to evaluate Iron trigluconic acid, trisodium salt for its ability to induce skin irritation on a human three dimensional epidermal model (EPISKIN Small model (EPISKIN-SMTM)). The possible skin irritation potential of Iron trigluconic acid, trisodium salt was tested through topical application for 15 minutes.

The study procedures described in this report were based on the most recent OECD and EC guidelines.

Batch FC-C 11988 of the test item was a yellow powder. Skin tissue was moistened with 5 µl of Milli-Q water and at least 10 mg of the test item was applied directly on top of the skin tissue for 15 ± 0.5 minutes. After a 42 hour post-incubation period, determination of the cytotoxic (irritancy) effect was performed. Cytotoxicity is expressed as the reduction of mitochondrial dehydrogenase activity measured by formazan production from MTT at the end of the treatment.

Skin irritation is expressed as the remaining cell viability after exposure to the test item. The relative mean tissue viability obtained after 15 ± 0.5 minutes treatment with Iron trigluconic acid, trisodium salt compared to the negative control tissues was 116%. Since the mean relative tissue viability for Iron trigluconic acid, trisodium salt was above 50% after 15 ± 0.5 minutes treatment, Iron trigluconic acid, trisodium salt is considered to be non-irritant.

The positive control had a mean cell viability of 5.7% after 15 ± 0.5 minutes exposure. The absolute mean OD570(optical density at 570 nm) of the negative control tissues was within the laboratory historical control data range. The standard deviation value of the percentage viability of three tissues treated identically was ≤ 18%, indicating that the test system functioned properly.

In conclusion, Iron trigluconic acid, trisodium salt is non-irritant in the in vitro skin irritation test under the experimental conditions described in this report andshould not be classified according to the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) of the United Nations.

Details on study design:
Within 2 hours after kill, eyes were carefully dissected and placed in a superfusion apparatus using the following procedure: First the eye-lids were carefully removed without damaging the cornea and a small drop of Fluorescein sodium 2.0% w/v (Minims, Chauvin, England) was applied to the corneal surface for a few seconds and subsequently rinsed off with isotonic saline at ambient temperature. Next, the head with the fluorescein-treated cornea was examined with a slit-lamp microscope (Slit-lamp 900 BP, Haag-Streit AG, Liebefeld-Bern, Switzerland) to ensure that the cornea was not damaged. If undamaged (e.g., fluorescein retention and corneal opacity scores of ≤ 0.5), the eye was further dissected from the head without damaging the eye or cornea. Care was taken to remove the eye-ball from the orbit without cutting off the optical nerve too short.
The enucleated eye was placed in a stainless steel clamp with the cornea positioned vertically and transferred to a chamber of the superfusion apparatus. The clamp holding the eye was positioned in such a way that the entire cornea was supplied with isotonic saline from a bent, stainless steel tube, at a target rate of 0.10-0.15 mL/min (peristaltic pump set at speed 5.00, Watson-Marlow 205CA, Rotterdam, the Netherlands). The chambers of the superfusion apparatus as well as the saline were temperature controlled at approximately 32oC (water pump set at 36.4oC; Lauda 103, Germany).
After placing in the superfusion apparatus, the eyes were examined again with the slit-lamp microscope to ensure that they were not damaged. Corneal thickness was measured using the Depth Measuring Attachment No. I for the Haag-Streit slit-lamp microscope, set at 0.095 mm.
Corneal thickness was expressed in instrument units. An accurate measurement was taken at the corneal apex of each eye.
Eyes with a corneal thickness deviating more than 10% of the average corneal thickness of the eyes, eyes showing opacity (score higher than 0.5), or were unacceptably stained with fluores-cein (score higher than 0.5) indicating the cornea to be permeable, or eyes that showed any other signs of damage, were rejected as test eyes and replaced.
Each eye provided its own baseline values for corneal swelling, corneal opacity and fluorescein retention. For that purpose, after an equilibration period of 45-60 minutes, the corneal thickness of the eyes was measured again to determine the zero reference value for corneal swelling calculations.
At time t = 0 (i.e. immediately after the zero reference measurement), the following procedure was applied for each test eye: The clamp holding the test eye was placed on paper tissues outside the chamber with the cornea facing upwards.
Next, the eyes (corneas) were treated with the study substance according to the following scheme:
negative control - saline - 30 uL - 10 sec - 20 ml saline for rinsing (one eye)
positive control - NaOH - 30 mg - 10 sec - 20 ml saline for rinsing (3 eyes)
test substance - 30 mg - - 10 sec - 20 ml saline for rinsing (3 eyes)
After rinsing, each eye in the holder was returned to its chamber.
The eyes were examined at approximately 0, 30, 75, 120, 180 and 240 minutes after treatment, using the criteria and scoring system given in the attachment. Fluorescein retention was only scored at approximately 30 minutes after treatment. All examinations were carried out with the slit-lamp microscope.
After the final examination, the test substance treated eyes, the negative and positive control eyes were preserved in a neutral aqueous phosphate-buffered 4% solution of formaldehyde. The corneas were embedded in paraffin wax, sectioned at ca 4 μm and stained with PAS (Periodic Acid-Schiff). The microscopic slides were subjected to histopathological examination.

Other effects / acceptance of results:
Microscopic examination of the cornea treated with the negative control (saline) did not reveal any abnormalities. Microscopic examination of the corneas treated with the positive control NaOH revealed severe erosion (3/3 corneas), severe necrosis (1/3 corneas) of the epithelium, disorder of stromal fibres (3/3 corneas) and endothelial necrosis (3/3 corneas). Microscopic examination of the corneas treated with Iron trigluconic acid, trisodium salt revealed very slight erosion of the epithelium in all three corneas.
Interpretation of results:
other: irritating in vitro
Conclusions:
Iron trigluconic acid, trisodium salt caused corneal effects consisting of no or very slight corneal swelling (mean of 1%), slight opacity (mean score of 1.0) and moderate fluorescein retention (mean score of 2.0). Therefore, an in vivo study was also performed.
Executive summary:

Iron trigluconic acid, trisodium salt was evaluated neat for eye irritation potential in the Isolated Chicken Eye (ICE) test. In addition, the test included a negative control (saline) and a positive control (NaOH). Chicken eyes were obtained from slaughter animals used for human consumption. The isolated chicken eyes were exposed to a single application of 30 mg of the test substance for 10 seconds followed by a 20 mL saline rinse. Three main parameters were measured to disclose possible adverse eye effects: corneal thickness (expressed as corneal swelling), corneal opacity and fluorescein retention of damaged epithelial cells. In addition, histopathology of the corneas was performed.

Iron trigluconic acid, trisodium salt caused corneal effects which could lead to a Category 2/2B classification, consisting of no or very slight corneal swelling (mean of 1%), slight opacity (mean score of 1.0) and moderate fluorescein retention (mean score of 2.0). Microscopic examination of the corneas revealed very slight erosion of the epithelium in all three corneas.

The negative control eye did not show any corneal effect and demonstrated that the general conditions during the tests were adequate. Microscopic examination of the cornea did not reveal any abnormalities. The positive control NaOH caused severe corneal effects and demonstrated the ICE test valid to detect severe eye irritants. Microscopic examination of the corneas revealed severe erosion (3/3 corneas), severe necrosis (1/3 corneas) of the epithelium, disorder of stromal fibres (3/3 corneas) and endothelial necrosis (3/3 corneas).

Applying the classification criteria of the ICE, the following irritation classifications can be assigned:

- Category 2B:“Mild irritant/causes eye irritation” (UN-GHS classification);

- Category 2:“Irritating to eyes” (EU-CLP classification).
