- Executive summary:
In a primary dermal irritation study (Kaysen A., 1984), young adult New Zealand White rabbits (6 males) were exposed by dermal contact to 0.5 ml of Metiloil A (batch No. 1169) (CAS No 67762-38-3) onto one flank. Test sites were covered with a semi-occlusive dressing for 4 hours. Animals then were observed for 3 days. Irritation was scored by the grading of skin reactions described in the OECD guideline 404. Slight erythema was observed in all animals after one hour exposure and disappeared completely after 3 days. No edema was observed. Mean scores over 1, 24, 48 and 72 hours were 2, 0.33, 0 and 0 for erythema and 0, 0, 0 and 0 for edema, respectivelly.
In this study, metiloil A is slightly irritating when applied topically to rabbit skin, but not classified according to the EU-GHS criteria.

Additional information
Based on GLP studies on the read-cross substance (CAS No 67762 -38 -3), the target substance Fatty acids, C18 (saturated and unsaturated) ethyl esters is not considered either a skin nor an eye irritant. In support for evaluation of eye irritation of Fatty acids, C18 (saturated and unsaturated) ethyl esters, no in vivo irritation potential was identified using the Hen's Egg Test utilizing the Chorioallantoic Membrane (HET-CAM). In terms of skin irritation, no skin irritation was seen in a human patch repeated insult patch test (HRIPT) using Bioester XP 3511F (atty acids, C18 (saturated and unsaturated) ethyl esters).
Justification for selection of skin irritation / corrosion endpoint:
GLP study on read-cross substance (CAS No 67762-38-3)
Justification for selection of eye irritation endpoint:
GLP study on read-cross substance (CAS No 67762-38-3)
Justification for classification or non-classification
Not classified. The test data shows that the target substance Fatty acids, C18 (saturated and unsaturated) ethyl ester is not considered to be a skin or eye irritant.
