Results
- Irritation parameter:
- other: Observation
- Score:
- ca. 0
- Max. score:
- 0
- Remarks on result:
- other: The was no numerical scoring used, but IUCLID TCC demands a value, so "0" was used as a placeholder.
- Irritant / corrosive response data:
- Slight or very slight edema was observed in one of 5 and 3 of 5 guinea pigs, respectively, at 24-48 hours after exposure to m-diisopropylbenzene. Edema was accompanied by moderate to severe erythema in 2 of 5 guinea pigs, and well-defined erythema in 2 of 5 guinea pigs. Moderate to severe erythema without edema was observed in one of 5 guinea pigs at 24-48 hours after exposure. For all test animals, there were no signs of edema or erythema at 2 weeks after exposure.
