DECISION CRITERIA
After the treatment with the test item, the mean value of relative tissue viability was in-creased to 102.9 %. This value is above the threshold for skin irritation potential (50%). Test items that induce values above the threshold of 50% are considered non-irritant to skin. - Control samples:
- yes, concurrent negative control
- yes, concurrent positive control
- Amount/concentration applied:
- One plate (3 tissues) was used as negative control; each tissue was treated with 30 µL DPBS buffer, a nylon mesh was added in order to ensure sufficient contact with the tis-sue surface.
One plate was used as positive control; each tissue was treated with 30 µL 5% SDS-solution, a nylon mesh was added in order to ensure sufficient contact with the tissue surface.
One plate was used for treatment with the test item:
30 µL test item were applied, and a nylon mesh was added in order to ensure sufficient contact with the tissue surface. - Duration of treatment / exposure:
- 1 hour
- Duration of post-treatment incubation (if applicable):

- Conclusions:
- After treatment, the respective substance was rinsed from the tissues. Then, cell viability of the tissues was evaluated by addition of MTT, which can be reduced to a blue forma-zan. Formazan production was evaluated by measuring the optical density (OD) of the re-sulting solution. After treatment with the negative control, the absorbance values were within the required acceptability criterion of mean OD ≥ 0.8 and ≤ 2.8 for both treatment intervals thus show-ing the quality of the tissues. The OD was 1.7 (3 minutes experiment) and 1.6 (1 hour ex-periment). The positive control showed clear corrosive effects for both treatment intervals. The mean relative tissue viability value was reduced to 6.1 % for the 1 hour treatment. After 3 minutes treatment with the test item, the mean value of relative tissue viability was increased to 102.6 %. This value is above the threshold for corrosion potential (50%). After 1 hour treatment, the mean value of relative tissue viability was increased to 105.0 %. This value, too, is above the threshold for corrosion potential (15%).
Therefore, Fatty Acids, vegetable-oil, Me-Esters, sulfurized is considered non-corrosive to skin in the Reconstructed Human Epidermis (RHE) Test Method. - Executive summary:
One valid experiment was performed.
Three tissues of the human skin model EpiDermTM were treated with Fatty Acids, vegetable-oil, Me-Esters, sulfurized for 60 minutes.
The test item was applied directly to each tissue and spread to match the tissue size (0.63 cm2; as indicated by the supplier).
DPBS-buffer was used as negative control and 5% SDS solution was used as positive control.
After treatment with the negative control, the mean absorbance values was within the required acceptability criterion of 0.8 ≤ mean OD ≤ 2.8, OD was 1.7. The positive control showed clear irritating effects. The mean value of relative tissue viability was reduced to 2.9 % (required: ≤ 20%).
The variation within the tissue replicates of negative, control, positive control and test item was acceptable (required: ≤ 18%).
After the treatment with the test item, the mean value of relative tissue viability was increased to 102.9 %. This value is above the threshold for skin irritation potential (50%). Test items that induce values above the threshold of 50% are considered non-irritant to skin.
Therefore, Fatty Acids, vegetable-oil, Me-Esters, sulfurized is considered
non-irritant to skin in the Reconstructed human Epidermis (RhE) Test Method.

- SELECTION AND PREPARATION OF CORNEAS
The corneas were examined and only corneas which were free from damages were used. The corneas were excised with a scalpel and cut from the globe with a 2-3 mm ring of sclera around the outside. Each cornea was transferred to a cornea holder in which pre-warmed cMEM (32 ± 1 °C) without phenol red was filled. The holders were then incubated for 1 hour in the incubation chamber at 32 ± 1 °C.
QUALITY CHECK OF THE ISOLATED CORNEAS
After the initial incubation, the medium was changed and the baseline opacity for each cornea was recorded. None of the corneas showed tissue damage; therefore, all corneas were used.
NUMBER OF REPLICATES
For each treatment group (negative control solution, test item and positive control), three replicates were used.
NEGATIVE CONTROL USED
HBSS: Hank’s Balanced Salt Solution (HBSS) 10-fold concentrated, diluted in demin. water (1:10), batch no.: 20171024
POSITIVE CONTROL USED
Dimethylformamide, DMF, CAS-No. 68-12-2, undiluted, batch no.: 475235719
APPLICATION DOSE AND EXPOSURE TIME
750 μL negative control solution, test item and positive control were applied to each replicate.
TREATMENT METHOD:
closed chamber
POST-INCUBATION PERIOD:
yes; 2 hours
REMOVAL OF TEST SUBSTANCE
After thorough rinsing with cMEM with phenol red and final rinsing with cMEM without phenol red, the anterior chamber was filled with cMEM without phenol red. After post-incubation time, the cMEM without phenol red was renewed in both chambers. Then, the final opacity value of each cornea was recorded.
METHODS FOR MEASURED ENDPOINTS:
- Corneal opacity:
The change of opacity value of each treated cornea with test item, positive control and negative control was calculated by subtracting the initial basal opacity from the post treatment opacity reading for each cornea. The average change in opacity of the negative control cornea was calculated and this value was subtracted from the change in opacity of each treated cornea with test item and positive control to obtain a corrected opacity.
- Corneal permeability:
Passage of sodium fluorescein dye measured with the aid of microtiter plate photometer (OD492)
SCORING SYSTEM:
In Vitro Irritancy Score (IVIS)
DECISION CRITERIA:
According to OECD Guideline no. 437 (Jul. 2013), a substance with an IVIS ≤ 3 requires no classification for eye irritation or serious eye damage. - Irritation parameter:
- in vitro irritation score
- Run / experiment:
- For each treatment group (negative control solution, test item and positive control), three replicates were used. Duration of each exposure: 10 minutes
- Value:
