Additional information
Skin irritation was tested in rabbits prior to the introduction of GLP and OECD testing guidelines (BASF 1976). The study is reported in sufficient detail for evaluation.
Twenty-four hours prior to dermal application, the backs of the rabbits were shaved over an area consisting of at least 10% of the total body surface. Two sites lateral to the midline of the back were used on each rabbit. Immediately before the application of the compound, the right hand side was abraded with the point of a sterile hypodermic needle. The abrasions were sufficiently deep to penetrate the stratum corneum but not to damage the dermis. The left hand side remained intact.
1g of the compound was applied in 50% aqueous suspension to both the abraded and intact test site on a 2.5cm square gauze pad. These were covered with aluminium foil secured with "Sleek" adhesive tape. After 24 hours the dressing was removed and the intact and abraded application sites were assessed for oedema and erythema. A further assessment was made on days 1,2,5,7 and 8.
The test item caused blue staining of the test item on day 1. After that no local effects were seen. The 24h-occlusive exposure is more stringent than the 4h-semiocclusive treatment prescrirbed in OECD testing guideline 404. The substance does not react with air and is not volatile, so that the occlusive conditions have no influence on the outcome. The substance is therefore considered to be non irritating to skin.
Eye irritation was tested in rabbits prior to the introduction of GLP and OECD testing guidelines (BASF 1976). The study is reported in sufficient detail for evaluation.
The procedure is similar to OECD testing guideline 405. It differs in the shorter observation time of 8 days and in that only 2 animals (Vienna White rabbits) were used.
Ca 50 mg of the test item was applied into one eye of each rabbit without the use of a vehicle. Considering the relative density, this is likely to amount to a volume of 0.1ml as required by the OECD testing guidline. The untreated eye served as control.
The test substance was not washed out. A scoring system translatable to Draize Scores was applied. On day eight, the eyes were investigated using fluorescein.
After 1h of application, grade 2 (of max 4) of irritation and dark bluish substance residues were observed for the treated eye of one animal. Grade 2 irritation (cornea and conjunctivae) was also observed at the 24h reading in one animal. Cornea findings were no longer observed at 24 and conjunctivae findings no longer at the 48h reading and no further effects were observed until the last investigation on day 8. No chemosis was observed at any time point. The second animal only showed signs of irritation at the 1h time point.
Therefore, the criteria for classification and labelling as an eye irritant (GHS criteria) are not fulfilled.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result, the substance is not considered to be classified for irritation under Regulation (EC) No. 1272/2008, as amended for the thirteenth time in Regulation (EC) No. 2018/1480.
