- Species:
- cattle
- Strain:
- not specified
- Details on test animals or tissues and environmental conditions:
- Eyes from adult cattle (typically 12 to 60 months) were obtained from a local abattoir as a by-product from freshly slaughtered animals. The eyes were excised by an abattoir employee after slaughter, and were placed in Hanks' Balanced Salt Solution (HBSS) supplemented with antibiotics (penicillin at 100 IU/mL and streptomycin at 100 ug/mL). They were transported to the test facility over ice packs on the same day of slaughter. The corneas were prepared immediately on arrival.

- Details on study design:
- SELECTION AND PREPARATION OF CORNEAS
The medium from both chambers of each holder was replaced with fresh complete EMEM. A pre-treatment opacity reading was taken for each cornea using a calibrated opacitometer. Three corneas were randomly allocated to the negative control. Three corneas were also allocated to the test item and three corneas to the positive control.
NUMBER OF REPLICATES
Triplcate
NEGATIVE CONTROL USED
Sodium chloride 0.9%w/v
POSITIVE CONTROL USED
Ethanol
APPLICATION DOSE AND EXPOSURE TIME
A volume of 0.75 mL of the test substance was applied to each of the three corneas followed by a 10 minute incubation at 32 oC.
POST-INCUBATION PERIOD: yes
REMOVAL OF TEST SUBSTANCE
- Number of washing steps after exposure period: 3
- POST-EXPOSURE INCUBATION: 120 minutes
METHODS FOR MEASURED ENDPOINTS:
- Corneal opacity: Labtech LT-4500 microplate reader
- Corneal permeability: passage of sodium fluorescein dye measured with the aid of microtiter plate reader (OD490)
SCORING SYSTEM: In Vitro Irritancy Score (IVIS)
Results and discussion
In vitro
Results
- Irritation parameter:
- in vitro irritation score
- Run / experiment:
- Mean score
- Value:
- 28.6
- Vehicle controls validity:
- not applicable
- Negative controls validity:
- valid
- Positive controls validity:
- valid
- Other effects / acceptance of results:
- OTHER EFFECTS:
- Visible damage on test system: The corneas treated with the test item were cloudy post-treatment and post-incubation. The corneas treated with the negative control were clear post-treatment and post-incubation. The corneas treated with the positive control item were cloudy post-treatment and post-incubation.
ACCEPTANCE OF RESULTS:
- Acceptance criteria met for negative control: The test was valid as the negative control produced an In Vitro Irritancy Score of 0.1 which is less than or equal to the upper limit for background opacity and permeability values calculated from the previous 12 months data for the testing facility.
- Acceptance criteria met for positive control: The test is normally acceptable if the positive control produced an In Vivo Irritancy Score which fell within two standard deviations of the historical mean collated during the previous 12 months for the testing facility. The positive control IVIS (30.3) was marginally below the normally accepted limit of 33.7-61.4. However, the data obtained was considered acceptable in demonstrating the sensitivity of the system. This IVIS score obtained does not qualify as an outlier (<26.8) and the data will be added to the historical control data, and is therefore accepted as a valid result.
Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (irritating to eyes) based on GHS criteria
- Remarks:
- According to the UN GHS Classification for the test item 2-propen-1-amine, N-2-propen-1-yl, hydrochloride, no prediction of eye irritation could be made under the conditions of the test. As the skin irritation study produced a non-irritant result, a worst-case scenario of GHS category 2 for eye irritation has been determined.
- Conclusions:
- No prediction could be made from the BCOP eye irritation study for 2-propen-1-amine, N-2-propen-1-yl, hydrochloride. Based on the information available from the skin irritation studies, a worst-case scenario prediction of GHS category 2 for eye irritation has been implemented.
- Executive summary:
An in vitro Bovine Corneal Opacity and Permeability (BCOP) assay was performed in line with OECD testing guideline 437. The study was GLP compliant.
The undiluted test material was applied neat to three cattle corneas obtained from a abattori at a volume of 0.75 mL, after which each cornea was incubated at 32 oC for 10 minutes. Opacity and permeability of corneas were measuring following exposure.
Negative and positive controls were considered valid.
No prediction could be made from the BCOP eye irritation study for 2-propen-1-amine, N-2-propen-1-yl, hydrochloride. Based on the information available from the skin irritation studies, a worst-case scenario prediction of GHS category 2 for eye irritation has been implemented.
