Applicant's summary and conclusion
- Interpretation of results:
- slightly irritating
- Remarks:
- Migrated information (Not Classified) Criteria used for interpretation of results: EU
- Conclusions:
- In this study, propane-1-thiol was observed to be slightly irritating to the eye (Moon, 1981).
- Executive summary:
In a primary eye irritation study (Moon, 1981), 0.1 millilitres of propane-1-thiol was placed on the everted lower lid of the right eye of six New Zealand white albino rabbits for seconds and then released. The left eye remained untreated and served as a control. Eyes were not washed after exposure. Animals were observed for 7 days post dosing. Irritation was scored by the method of Draize.
Ocular irritation was observed in all of the test animals following exposure (mean irritation score = 8.3, 2.0, 4.3, and 4.3 for 1, 24, 48, and 72 hours respectively). All signs of irritation dissipated at the end of the 7 day observation period. The combined weight gain from day of dosing to day 7 was approximately 83 grams. In this study, propane-1-thiol was considered to be slightly irritating to the eye based on the Draize method.
This study received a Klimisch score of 2 and is classified as reliable with restrictions because it complies with GLP and adheres closely to OECD guideline 405.
