- Test item was applied for 10 seconds to the cornea
- Number of animals or in vitro replicates:
- 1 eye for negative control and 3 eyes for positive control and test item
- Details on study design:
- SELECTION AND PREPARATION OF ISOLATED EYES
- The eyelids were carefully excised, taking care not to damage the cornea. Then, the eye was further dissected from the skull, taking care not to damage the cornea. The eyeball was pulled from the orbit by holding the nictitating membrane firmly with surgical forceps, and the eye muscles were cut with a bent, blunt-tipped scissor. When the eye is removed from the orbit, a visible portion of the optic nerve should be left attached. Once removed from the orbit, the eye was placed on an absorbent pad and the nictitating membrane and other connective tissue were cut away.
- The enucleated eye was mounted in a stainless steel clamp with the cornea positioned vertically. The clamp was then transferred to a chamber of the superfusion apparatus. The clamps were positioned in the superfusion apparatus such that the entire cornea was supplied with the physiological saline drip (in the range 0.1 to 0.15 mL/min). The chambers of the superfusion apparatus was temperature controlled at 32 °C.
- After being placed in the superfusion apparatus, the eyes were examined with a slit-lamp microscope to ensure that they have not been damaged during the dissection procedure. Corneal thickness was also measured at this time at the corneal apex using the depth measuring device on the slit-lamp microscope. Eyes with; (i), a fluorescein retention score of > 0.5; (ii) corneal opacity > 0.5; or, (iii), any additional signs of damage were replaced. For eyes that are not rejected based on any of these criteria, individual eyes with a corneal thickness deviating more than 10% from the mean value for all eyes are to be rejected.
- Once all eyes had been examined and approved, the eyes were incubated between 45 and 61 minutes to equilibrate them to the test system prior to dosing. Following the equilibration period, a zero reference measurement was recorded for corneal thickness and opacity to serve as a baseline (i.e., time = 0). The fluorescein score determined at dissection was used as the baseline measurement for that endpoint.
APPLICATION DOSE AND EXPOSURE TIME
- Immediately following the zero reference measurements, the eye (in its holder) was removed from the superfusion apparatus, placed in a horizontal position, and 30 µL of the test item was applied to the cornea such that the entire surface of the cornea was evenly covered with the test item. The test item was applied for 10 seconds.
REMOVAL OF TEST SUBSTANCE
- After exposure, test item was rinsed twice from the eye with 10 mL of physiological saline at ambient temperature. The eye (in its holder) was subsequently returned to the superfusion apparatus in the original upright position.
OBSERVATION PERIOD
- Treated corneas were evaluated before the pre-treatment and at 30, 75, 120, 180, and 240 minutes (± 5 minutes) after the post-treatment rinse.
METHODS FOR MEASURED ENDPOINTS:
- All observations of the cornea and measurement of corneal thickness were performed using a Haag-Streit BP900 slit-lamp microscope with depth-measuring device no. I. For the measurement of corneal thickness, the slit-width was set at 9½, equalling 0.095 mm.
- The endpoints evaluated were corneal opacity, swelling, fluorescein retention, and morphological effects (e.g., pitting or loosening of the epithelium). All of the endpoints, with the exception of fluorescein retention (which was determined only at pretreatment and 30 minutes after exposure to the test item) were determined at each of the above time points.
SCORING SYSTEM:
- Mean corneal swelling (%): Corneal swelling was determined from corneal thickness measurements made with an optical pachymeter on a slit-lamp microscope.
Corneal swelling (%) = ((corneal thickness at time t - corneal thickness at time = 0) / (corneal thickness at time = 0)) x 100
The mean percentage of corneal swelling for all tested eyes was calculated for all observation time points. Based on the highest mean score for corneal swelling, as observed at any time point, an overall category score was then given for the test item.
- Mean maximum opacity score: Corneal opacity was calculated by using the area of the cornea that was most densely opacified for scoring. The mean corneal opacity value for all tested eyes was calculated for all observation time points. Based on the highest mean score for corneal opacity, as observed at any time point, an overall category score was then given for each test or control item.
0: No opacity
0.5: Very faint opacity
1: Scattered or diffuse areas; details of the iris clearly visible
2: Easily discernible translucent area; details of the iris are slightly obscured
3: Severe corneal opacity; no specific details of the iris are visible; size of the pupil is barely discernible
4: Complete corneal opacity; iris invisible
- Mean fluorescein retention score at 30 minutes post-treatment: The mean fluorescein retention value for all tested eyes was calculated for the 30-minute observation time point only, which was used for the overall category score given for each test or control item.
0: No fluorescein retention
0.5: Very minor single cell staining
1: Single cell staining scattered throughout the treated area of the cornea
2: Focal or confluent dense single cell staining
3: Confluent large areas of the cornea retaining fluorescein
DECISION CRITERIA:
- Results from corneal opacity, swelling, and fluorescein retention were evaluated separately to generate an ICE class for each endpoint. The ICE classes for each endpoint were then combined to generate an Irritancy Classification for the test item.
- Once each endpoint was evaluated, ICE classes were assigned based on a predetermined range. Interpretation of corneal thickness, opacity, and fluorescein retention using four ICE classes was done according to the table 7.3.2/1, 7.3.2/2, 7.3.2/3. - Irritation parameter:

- Executive summary:
An ex vivo eye irritation study was performed according to the OECD Guideline 438 and in compliance with GLP to evaluate the possible ocular corrosive or severe irritating effects of the test item after administration on enucleated chicken eyes.
The test item was applied, after incubation during 30 minutes at 45°C and 15 min at room temperature, at the dose of 30 µL, to 3 enucleated chicken eyes during 10 seconds. Then the eyes were rinsed twice with 10 mL of physiological saline. Three eyes were treated in the same manner with a positive control and one eye with a negative control. Damages by the test item were assessed by determination of corneal swelling, opacity, and fluorescein retention at -45, 30, 75, 120, 180 and 240 minutes post-dose.
The ocular reactions observed in eyes treated with the test item were:
- maximal mean score of corneal opacity: 1.0, corresponding to ICE class II;
- mean score of fluorescein retention: 2.0, corresponding to ICE class III;
- maximal mean corneal swelling: 14%, corresponding to ICE class II.
The combination of the three endpoints for test item CORIANDRE GRAINES ESS C43451 was 2 x II, 1 x III.

Eye irritation
A key study (ICARE, 2021) is available.
An ex vivo eye irritation study was performed according to the OECD Guideline 438 and in compliance with GLP to evaluate the possible ocular corrosive or severe irritating effects of the test item after administration on enucleated chicken eyes.
The test item was applied, after incubation during 30 minutes at 45°C and 15 min at room temperature, at the dose of 30 µL, to 3 enucleated chicken eyes during 10 seconds. Then the eyes were rinsed twice with 10 mL of physiological saline. Three eyes were treated in the same manner with a positive control and one eye with a negative control. Damages by the test item were assessed by determination of corneal swelling, opacity, and fluorescein retention at -45, 30, 75, 120, 180 and 240 minutes post-dose.
The ocular reactions observed in eyes treated with the test item were:
- maximal mean score of corneal opacity: 1.0, corresponding to ICE class II;
- mean score of fluorescein retention: 2.0, corresponding to ICE class III;
- maximal mean corneal swelling: 14%, corresponding to ICE class II.
The combination of the three endpoints for test item CORIANDRE GRAINES ESS C43451 was 2 x II, 1 x III.
The combination of the three endpoints for the positive control, 5% Benzalkonium chloride, was 3 x IV. Therefore, the positive control is classified as "Corrosive/Severe Irritant", as expected.
The combination of the three endpoints for the negative control, physiological saline, was 3 x I. Therefore, the negative control is classified as “No Category”, as expected.
In accordance with Regulation (EC) No. 1272/2008, the results obtained under these experimental conditions lead to category “no prediction can be made”, as defined by OECD guideline No. 438. Therefore, the test item CORIANDRE GRAINES ESS C43451 is not predicted as causing serious eye damage (Category 1) or as not classified for eye irritation/serious eye damage (No category) with the Isolated Chicken Eye test.
Justification for classification or non-classification
Harmonized classification:
The registered substance has no harmonized classification according to the Regulation (EC) No. 1272/2008.
Self-classification:
Based on the available information and typical composition provided by the Lead Registrant, the registered substance is classified as skin irritant: Skin Irritant Category 2 (H315: Causes skin irritation) and Eye irritant category 2 (H319: Causes serious eye irritation) according to the criteria of the Regulation (EC) No. 1272/2008 (CLP).
To reach this conclusion on the classification of the substance, an assessment of the eye corrosivity has been performed: the in vitro study (OECD 438) did not allow to discriminate between the corrosion potential of the substance and the non-classification ("no prediction can be made").
This study is considered sufficient with the following arguments:
- Skin irritation/corrosion:
1/ Calculation rules have allowed to classify the substance as Skin irritant
2/ no constituents were classified as "skin corrosive" based on the 100% known composition of the UVCB and the available data on each constituent.
3/ the eye corrosion study did not indicate that the test item was corrosive to the eyes, therefore, the substance is not expected to be corrosive to the skin
- Eye irritation/corrosion:
1/ the eye corrosion study confirmed the absence of corrosive or severe irritating effects and did not indicate that the test item was corrosive to the eyes, from a sample where the H318 constituents (camphor and geraniol, 4.27 % and 2.04%, respectively) were above the threshold for classification as H318 (≥ 3%).
According to these arguments, it can therefore be concluded that the test item is not considered as an eye and skin corrosive.
