Additional information

There are valid in-vivo data available for the assessment of the skin and eye irritation potential.

Skin

In an acute dermal irritation or corrosion study according to OECD 404 and GLP, 0.5 ml of the test substance were topically applied to the intact skin of 3 White Vienna rabbits for 4 hours under semiocclusive dressing (BASF AG 1991). The average score (24 to 72 hours) for irritation was calculated to be 0.3 for erythema and 0.0 for edema, thus the test substance was only slightly irritating in this assay.

Two further studies are available where rabbits were treated with the test substance on abraded and non-abraded skin areas for 24h under occlusive conditions. Due to the harsh conditions compared to current guidelines and because two valid studies are available, the results were only used as supplemental information.

A single dose of 0.5 ml of the test substance applied to a 6 cm² scarified or non-scarified clipped area of the skin of 6 male New Zealand White rabbits (BASF AG 1994) caused only slight irritation. The test substance was held in contact with the skin for 24 hours by means of an occlusive hypoallergenic dressing. Cutaneous reactions were observed approximately 24 and 72 hours after application of the test substance. The Cutaneous Primary Irritation index was: 1.4. Since the animals were only observed for 72h, reactions persisted in a few rabbits until the end of the study. 

Six rabbits were each administered a dermal dose of 0.5 ml of the test substance to one intact and one abraded skin site and observed for three days (BASF Japan 1997). The method followed was that described in Code of Federal Regulations, Title 16, Section 1500.41. A single occlusive application to intact and abraded rabbit skin for twenty-four hours elicited no dermal irritation.

The Primary Irritation Index (PII) was calculated to be 0.9.

Eye:

3 white Vienna rabbits were subjected to a single ocular application of 0.1ml of the test substance on day 0 in a GLP study according to OECD 405 (BASF AG 1991) . The average scores (24 to 72h) for the first rabbit were calculated to be 0.0 for corneal opacity, 0.0 for iris.
