- Remarks:
- Negative control HBSS solution, Positive control Dimethylformamide (undiluted)
- Controls:
- yes
- Amount / concentration applied:
- The respective substance (negative control solution, test item or positive control) was applied by pipetting 750 μL of the appropriate liquid through the refill hole in the holder on the cornea. The test item was given on the epithelium in such a manner that as much as possible of the cornea was covered with the test item.

- Exposure time on the corneas was 10 minutes at 32 ± 1 °C.
- Duration of post- treatment incubation (in vitro):
- 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, and the corneas were stored for additional 2 hours at 32 ± 1 °C (post-incubation).

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Jasmonyl LG is not irritating to the eye.
- Executive summary:
This in vitro study was performed to assess corneal damage potential of Jasmonyl LG by quantitative measurements of changes in opacity and permeability in a bovine cornea.
The test item Jasmonyl LG was brought onto the cornea of a bovine eye which previously had been incubated with cMEM without phenol red at 32 ± 1 °C for 1 hour and whose opacity had been determined. The test item was incubated on the cornea for 10 minutes at 32 ± 1 °C. After removal of the test item and 2 hours post-incubation, opacity and permeability values were measured.
The test item was tested pure.
Under the conditions of this test, the test item Jasmonyl LG showed no effects on the cornea of the bovine eye. The calculated IVIS (in vitro irritancy score) is 1.93.
According to OECD Guideline no. 437 (Jul. 2013), a substance with an IVIS ≤ 3 requires no classification for eye irritation or serious eye damage.
The negative control (HBSS-solution) and the positive control (undiluted dimethylformamide) have met the validity criteria.
No observations were made which might cause doubts concerning the validity of the study outcome. The test is considered valid.
