Constituent 1
- Specific details on test material used for the study:
- - Name of test material (as cited in study report): HEXENYL-3-CIS-ISOBUTYRATE
- Physical state: colourless liquid
- Lot/batch No.: VE00468943
- Expiration date of the lot/batch: 12 November 2017
Test animals / tissue source
- Species:
- cattle
- Details on test animals or tissues and environmental conditions:
- Test System: Bovine eyes were used as soon as possible after slaughter.
Rationale: In the interest of sound science and animal welfare, a sequential testing strategy is recommended to minimize the need of in vivo testing (1-6). As a consequence a validated and accepted in vitro test for eye irritation should be performed before in vivo tests are conducted. One of the proposed validated in vitro eye irritation tests is the Bovine Corneal Opacity and Permeability (BCOP) test.
Source: Bovine eyes from young cattle were obtained from the slaughterhouse (Vitelco, 's Hertogenbosch, The Netherlands), where the eyes were excised by a slaughterhouse employee as soon as possible after slaughter.
Transport: Eyes were collected and transported in physiological saline in a suitable container under cooled conditions.
Test system
- Vehicle:
- unchanged (no vehicle)
- Remarks:
- The test item was tested neat.
- Controls:
- yes, concurrent positive control
- yes, concurrent negative control
- Amount / concentration applied:
- The test item was applied as it is (750 μl) directly on top of the corneas
- Duration of treatment / exposure:
- topical application for 10 minutes
Results and discussion
In vitro
Results
- Irritation parameter:
- in vitro irritation score
- Value:
- -1
- 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:
- 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 64 and was 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.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In conclusion, since HEXENYL-3-CIS-ISOBUTYRATE induced an IVIS ≤ 3, no classification is required for eye irritation or serious eye damage.
- Executive summary:
The objective of this study was to evaluate the eye hazard potential of HEXENYL-3-CISISOBUTYRATE as measured by its ability to induce opacity and increase permeability in an isolated bovine cornea using the Bovine Corneal Opacity and Permeability test (BCOP test). This report describes the potency of chemicals to induce serious eye damage using isolated bovine corneas. The eye damage of HEXENYL-3-CIS-ISOBUTYRATE was tested through topical application for 10 minutes.
The study procedures described in this report were based on the most recent OECD guideline.
Batch VE00468943 of HEXENYL-3-CIS-ISOBUTYRATE was a colourless to pale yellow liquid. The test item was applied as it is (750 μl) directly on top of the corneas. 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 64 and was 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.
HEXENYL-3-CIS-ISOBUTYRATE did not induce ocular irritation through both endpoints, resulting in a mean in vitro irritancy score of -1.0 after 10 minutes of treatment.
In conclusion, since HEXENYL-3-CIS-ISOBUTYRATE induced an IVIS ≤ 3, no classification is required for eye irritation or serious eye damage.
