Constituent 1
Test animals / tissue source
- Species:
- other: Bovine eye
- Details on test animals or tissues and environmental conditions:
- Origin: Bovine eyes were obtained from freshly slaughtered cattle at the abattoir EVA, Saint-Pierre-sur-Dives, France.
Age: bovine cattle were up to 12 months old.
Reason for choice: Bovine corneas are recommended by regulatory authorities for this type of study. They are adapted for the evaluation of potential ocular irritants since they are part of the target organ.
Transport from supplier to CiToxLAB France: Eyes were transported to CiToxLAB France at ambient temperature, immerged in buffered Hanks medium containing an antibiotic [Hank’s Balanced Salts Solution (HBSS) plus penicillin/streptomycin (100 units/100 μg/mL final)]. A container with smooth internal surfaces was used for the transport to avoid damage to the corneas.
Test system
- Vehicle:
- unchanged (no vehicle)
- Controls:
- yes, concurrent positive control
- yes, concurrent negative control
- Amount / concentration applied:
- TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 750 μL (± 8 μL) was applied on each cornea
- Concentration (if solution): undiluted - Duration of treatment / exposure:
- The test item was evaluated by using a treatment time of 10 minutes ± 30 seconds.
- Number of animals or in vitro replicates:
- Total: 9 corneas - 3 corneas/group for test item, negative and positive controls
- Details on study design:
- Dose formulation application:
As the test item is a non-surfactant liquid, it was tested undiluted. As the test item could be sampled using a micropipette, a volume of 750 μL (± 8 μL) was applied on each cornea using the closed-chamber method as follows: the test and control items were introduced into the anterior chamber of the corneal holder through the dosing holes, to cover the epithelial side of the cornea. Then the dosing holes were sealed.
Treatment of corneas:
Corneas obtained from freshly slaughtered cattle (from abattoir) were mounted in corneal holders with the endothelial side against the O-ring of the posterior chamber. For pre-incubation, both chambers of the corneal holder were filled with MEM culture media supplemented with 1% fetal bovine serum plus penicillin/streptomycin (cMEM) and incubated for 1 h and 5 minutes (± 5 minutes) at 32 ± 1 °C. Then medium was removed & then refilled with fresh cMEM and corneas were examined macroscopically for any defects. Then, the opacity of the cornea was measured to obtain OPT0. The medium was removed from anterior chamber and the test item was applied onto the epithelium of the cornea. After application of the dose formulation, the holders were incubated, vertically (cornea positioned horizontally with the treated side uppermost) in a water bath at 32 ± 1 °C, for 10 minutes ± 30 seconds. At the end of the exposure period, the test item was removed from the anterior chamber and the corneas were rinsed up to five times with pre-warmed cMEM containing phenol red. Then, the corneas were finally rinsed with pre-warmed cMEM without phenol red. Following the 10-minute treatment, the holders were incubated horizontally (corneas placed vertically) for 2 h ± 10 minutes in a water bath at 32 ± 1 °C. After completion of the 2 h incubation period, the medium of both anterior and posterior chambers was renewed with pre-warmed cMEM (32 ± 1 °C), then the second opacity measurement (OPT2) was performed.
Permeability determination
- Application of sodium fluorescein: Following the opacity measurement the permeability of the corneas to sodium fluorescein was evaluated. The medium of the anterior chamber was removed and the chamber received 1 mL of a fluorescein solution (4 mg/mL). For each series of three corneas, a chronometer started from the fluorescein application time of the first cornea of the series. The holders were incubated vertically (cornea positioned horizontally with the fluorescein-treated side uppermost) in a water bath at 32 ± 1 °C for 90 ± 5 minutes. After incubation the medium in the posterior chamber of each holder was decanted and retained. Then optical density at 490 nm (OD490) was measured using the spectrophotometer.
CONTROLS:
Negative control: 0.9 % sodium chloride solution
Positive control: 10% sodium hydroxide solution
OTHERS:
- Macroscopic examination: After permeability determination, the corneas were removed from the holders and observed for opaque spots, other irregularities and any separation of the epithelium. Then, the corneas were discarded.

Applicant's summary and conclusion
- Interpretation of results:
- other: could not be predicted
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:
- Under the experimental conditions of this study, the ocular corrosive or severe irritant potential of the test item, Cade Oil, could not be predicted. The test item could not be identified as inducing serious eye damage (UN GHS and EU CLP Category 1) or as a test chemical not requiring classification for eye irritation or serious eye damage (UN GHS and EU CLP No Category).
- Executive summary:
In an in vitro eye irritation study performed according to the OECD Guideline 437 and in compliance with GLP, 750 μL (± 8 μL) of undiluted test item, Cade Oil was applied to isolated bovine corneas for 10 minutes followed by an incubation period of 2 h at 32 °C. Three corneas were used for each treated series (undiluted test item; negative control; positive control). Before the treatment, a first opacity measurement was performed using an opacitometer. After the second opacity measurement, the medium of the anterior chamber was removed and filled with a fluorescein solution. The holders were then incubated vertically for 90 minutes at 32 °C. At the end of the incubation period, the optical density of the solution from the posterior chamber of each holder was measured in order to determine the permeability of the cornea. Each cornea was then observed for opaque spots and other irregularities.
No notable opaque spots or irregularities were observed on negative control corneas. Fluorescein fixation was observed on the corneas treated with the test item. Opacity, fluorescein fixation and thickening of the corneas were observed on those treated with the positive control.In Vitro Irritancy Score (IVIS) for test item and positive control were 31 and 271, respectively.
As the test item-induced a mean IVIS > 3 and ≤ 55, the eye hazard potential of the test item could not be predicted. The test item could not be identified as inducing serious eye damage (UN GHS Category 1) or as a test chemical not requiring classification for eye irritation or serious eye damage (UN GHS No Category).
