Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this study, the LD50 of 1-Octanal, was determined to be 6.35 ml/kg bw which is equivalent to 5207 mg/kg bw . Based on this result, the test substance does not warrant any classification in accordance with Regulation EC No. 1272/2008.
- Executive summary:
In a study conducted by Smyth et al (1962) 1-Octanal, was tested for its ability to cause acute dermal toxicity when applied to male New Zealand White albino rabbits. The entire trunk of each test animal was shaved prior to application of the test material and the test substance was applied. An impervious dressing was applied to the test site and remained in place for the 24 hours exposure period. During this exposure period, the test animals were placed in restraint tubes. Following exposure, the test animals were placed in cages for the 14 day observation period. Under the conditions of this study, the LD50 of 1-Octanal, was determined to be 6.35 ml/kg bw, equivalent to 5207 mg/kg bw. Based on this result, the test substance does not warrant classification for acute dermal toxicity in accordance with Regulation EC No. 1272/2008.
