Additional information
In a study, which was in large part equivalent to the methods described in OECD Guideline 404, irritant effects to skin were detected. Even after an application time of 15 min prominent erythema at 24 - 72 h and desquamation after 8 days after the application were found (BASF AG, 1969). When 0.5 ml was applied to rabbit eyes, no irritant effects were observed (BASF AG, 1969).
Effects on skin irritation/corrosion: irritating
Justification for classification or non-classification
Due to results obtained in studies, which were in large part similiar to OECD Guidelines, 2,5,6 -Trimethyl-2-cyclohexene-1-one has to be classsified as irritant to skin, but not classified as irritant to eyes.
