- None reported
- Interpretation of results:
- other: Not classified through EU CLP; not irritating
- Remarks:
- Criteria used for interpretation of results: EU
- Conclusions:

- Executive summary:
In a primary dermal irritation study, young adultwhite rabbits (3/sex) were dermally exposed to 0.5 millilitres of 1-hexene, 99.4% pure, for 4 hours to 2 centimetres x 2 centimetres of body surface area. Animals then were observed for 7 days. Irritation was scored based on OECD guidelines, on a scale of 0 to 4.
The application of 1 -hexene resulted in no skin reactions, with a mean irritation score of 0 for erythema and oedema at all time points.In this study, 1-hexene is not a dermal irritant.
This study received a Klimisch score of 1and is classified asreliable without restriction, because the study was carried out closely following OECD Guideline 404 and was GLP compliant.
The test material was classified as non-irritating because the group mean was 0 for both erythema and oedema at 24, 48, and 72 hours.
