The relative mean tissue viability obtained after 15 ± 0.5 minutes treatment with Gurjun balsam oil (Gurjunene) compared to the negative control tissues was 82%. Since the mean relative tissue viability for testing material was above 50% after 15 minutes treatment it is not considered to be an irritant. Both the positive and the negative control were within the historical control data range and therefore considered valid. Furthermore, the standard deviation value of the percentage viability of three tissues treated identically was less than 13%, indicating that the test system functioned properly. Gurjun balsam oil (Gurjunene) was determined to non-irritant in the in vitro skin irritation test under the experimental conditions described in this report. Therefore it can be concluded that Gurjun balsam oil (Gurjunene) does not need to be classified for skin irritation in accordance with the criteria outlined in Annex I of the CLP Regulation (1272/2008/EC).

- SELECTION AND PREPARATION OF CORNEAS
- The eyes were checked for unacceptable defects, such as opacity, scratches, pigmentation and neovascularization by removing them from the physiological saline and holding them in the light. Those exhibiting defects were discarded. The isolated corneas were stored in a petri dish with cMEM (Earle’s Minimum Essential Medium (Life Technologies, Bleiswijk, The Netherlands) containing 1% (v/v) L-glutamine (Life Technologies) and 1% (v/v) Foetal Bovine Serum (Life Technologies)). The isolated corneas were mounted in a corneal holder (one cornea per holder) of BASF (Ludwigshafen, Germany) with the endothelial side against the O-ring of the posterior half of the holder. The anterior half of the holder was positioned on top of the cornea and tightened with screws. The compartments of the corneal holder were filled with cMEM of 32+/-1°C. The corneas were incubated for the minimum of 1 hour at 32+/-1°C.
QUALITY CHECK OF THE ISOLATED CORNEAS
- Opacity determinations were performed on each of the corneas using an opacitometer (BASF-OP3.0, BASF, Ludwigshafen, Germany). The opacity of each cornea was read against a cMEM filled chamber, and the initial opacity reading thus determined was recorded. Corneas that had an initial opacity reading higher than 7 were not used. Three corneas were selected at random for each treatment group.
NUMBER OF REPLICATES : 3
NEGATIVE CONTROL USED:
- Physiological saline (Eurovet Animal Health, Bladel, The Netherlands)
POSITIVE CONTROL USED :
- Ethanol, Batch K47177483, Identification number RS532, Purity >99.9% Stable under storage conditions until 31 October 2020
APPLICATION DOSE AND EXPOSURE TIME
- Undiluted, 10+/-1 minutes
TREATMENT METHOD:
- The isolated corneas were mounted in a corneal holder (one cornea per holder) with the endothelial side against the O-ring of the posterior half of the holder. The anterior half of the holder was positioned on top of the cornea and tightened with screws. The compartments of the corneal holder were filled with cMEM of 32 +/- 1°C. The corneas were incubated for the minimum of 1 hour at 32 +/- 1°C.
REMOVAL OF TEST SUBSTANCE
- Number of washing steps after exposure period: 2
POST-EXPOSURE INCUBATION:
- yes; 120+/-10 minutes
METHODS FOR MEASURED ENDPOINTS:
- Corneal opacity: The opacity of a cornea was measured by the diminution of light passing through the cornea.The light was measured as illuminance (I = luminous flux per area, unit: lux) by a light meter.
- Corneal permeability: passage of sodium fluorescein dye measured with the aid of a microplate reader (TECAN Infinite® M200 Pro Plate Reader).
SCORING SYSTEM: In Vitro Irritancy Score (IVIS)
ACCEPTABILITY CRITERIA
The assay is considered acceptable if:
1) The positive control gives an in vitro irritancy score that falls within two standard deviations of the current historical mean.
2) The negative control responses should result in opacity and permeability values that are less than the upper limits of the laboratory historical range.
All results presented in the tables of the report are calculated using values as per the raw data rounding procedure and may not be exactly reproduced from the individual data presented.
EVALUATION CRITERIA
The mean opacity and mean permeability values (OD490) were used for each treatment group to calculate an in vitro score: In vitro irritancy score (IVIS) = mean opacity value + (15 x mean OD490 value) Additionally the opacity and permeability values were evaluated independently to determine whether the test item induced irritation through only one of the two endpoints. The IVIS cut-off values for identifying the test items as inducing serious eye damage (UN GHS Category 1) and test items not requiring classification for eye irritation or serious eye damage (UN GHS No Category) are: ≤ 3: No Category, > 3 ≤ 55: No prediction can be made, >55: Category 1 - Irritation parameter:
- in vitro irritation score
- Run / experiment:
- Main
- Value:
- -0.5
- Vehicle controls validity:
- not applicable
- Negative controls validity:
- valid
- Positive controls validity:
- valid
- Remarks on result:
- no indication of irritation
- Other effects / acceptance of results:
- OTHER EFFECTS:
- Visible damage on test system: not reported.
DEMONSTRATION OF TECHNICAL PROFICIENCY:
- The negative control responses for opacity and permeability were less than the upper limits of the laboratory historical range indicating that the negative control did not induce irritancy on the corneas. The mean in vitro irritancy score of the positive control (Ethanol) was 48 and within two standard deviations of the current historical positive control mean. It was therefore concluded that the test conditions were adequate and that the test system functioned properly.
ACCEPTANCE OF RESULTS:
- Acceptance criteria met for negative control: yes
- Acceptance criteria met for positive control: yes
- Range of historical values if different from the ones specified in the test guideline:
Negative control
-opacity -2.9-3.0 (SD 1.06, n=101)
-permeability -0.034 – 0.100 (SD 0.01, n=101)
-IVIS -2.8-3.0 (SD 1.12, n=101)
Positive control
-IVIS 28.0 – 110.9 (SD 15.67, n=76) - Interpretation of results:
- other: not classified
- Remarks:
- based on CLP criteria (Annex I of 1272/2008/EC)
- Conclusions:
- Gurjun balsam oil (Gurjunene) induced an IVIS ≤ 3. Based on these results, the test substance does not need to be classified as eye irritant according to the classification criteria outlined in Annex I of 1272/2008/EC (CLP).
- Executive summary:
The eye hazard potential of Gurjun balsam oil (Gurjunene) was evaluated according to OECD TG 437 (BCOP test). The eye damage was assessed through topical application of 750 μl of the undiluted testing material for 10 minutes on top of the corneas. Both the negative control and the positive control (Ethanol) were considered valid. It was therefore concluded that the test conditions were adequate and that the test system functioned properly. Gurjun balsam oil (Gurjunene) did not induce ocular irritation (no opacity and no permeability), resulting in a mean in vitro irritancy score of -0.5 after 10 minutes of treatment. In conclusion, Gurjun balsam oil (Gurjunene) induced an IVIS ≤ 3, and therefore test substance does not need to be classified as eye irritant according to the classification criteria outlined in Annex I of 1272/2008/EC (CLP).

Skin irritation
The skin irritation potential of Gurjun balsam oil (Gurjunene) was tested in accordance toOECDTG 439. Undiluted testing material was topically applied to EPISKIN-SMTM for 15 minutes.
After a 42 hour post-incubation period, determination of the cytotoxic (irritancy) effect was performedusing MTT conversion measurements.The relative mean tissue viability obtained after 15 ± 0.5 minutes treatment with Gurjun balsam oil (Gurjunene) compared to the negative control tissues was 82%. Since the mean relative tissueviability for testing material was above 50% after 15 minutes treatment it is not considered to be an irritant. Both the positive and the negative control were within the historical control data range and therefore considered valid. Furthermore, the standard deviation value of the percentage viability of three tissues treated identically was less than 13%, indicating that the test system functioned properly.Gurjun balsam oil (Gurjunene) was determined to non-irritant in the in vitro skinirritation test under the experimental conditions described in this report.
