SCORING SYSTEM:
- Treated sites were scored for erythema, oedema, cracking and scaling and any other feature using an 8-point anchored ordinate scale ranging from "a" (very slight) to "h" (severe). For better interpretation, an equivalence with OECD guideline 404 scoring system was made (see table 1)

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the test conditions, the substance induced only moderate skin irritation in rabbits. As overall mean scores for erythema and oedema were lower than 2, the substance should not be classified according to Directive 67/548/EEC and CLP Regulation (EC) N° 1272/2008.
- Executive summary:
In a primary dermal irritation study performed similarly to OECD Guideline 404, eight New Zealand White rabbits were dermally exposed to 0.5 mL of the substance (100 %) under a semi-occlusive dressing for 4 h. After removal of the residual test item, treated sites were scored for erythema, oedema, cracking and scaling and any other feature using an 8-point anchored ordinate scale ranging from very slight to severe at 24, 48 and 72 h after exposure. Cyclamen aldehyde and diethyl phthalate were used as standards for comparison.
The substance produced fairly distinct to distinct erythema and oedema with slight to distinct cracking and scaling. The overall level of response was similar to that produced by cyclamen aldehyde although cyclamen aldehyde produced slightly more erythema and oedema and slightly less cracking and scaling. Response to the substance was greater than that produced by diethyl phthalate which produced only marginal to slight erythema and oedema with marginal cracking and scaling. When using an equivalence between this scoring scale and the OECD 404 scoring system, the overall mean scores at 24, 48 and 72 h were 1.8 and 1.7 for erythema and oedema, respectively.
Under the test conditions, the substance induced only moderate skin irritation in rabbits. As overall mean scores for erythema and oedema were lower than 2, the substance should not be classified for skin irritation according to Directive 67/548/EEC and CLP Regulation (EC) N° 1272 /2008.
