- RANGE FINDING TESTS: The objective of this investigation was to identify a maximally tolerated concentration of the test article suitable for the induction phase of the main study. In addition, a suitable non-irritant concentration of the test article, by the topical route of administration, was identified for the challenge application.
The procedure employed for these investigations was as follows:
INTRADERMAL INJECTIONS: Intradermal injections (0.1 ml/site) were made into the clipped flank of two guinea-pigs at concentrations of 5, 3 and 1 % of the test article in bi-distilled water. The resulting dermal reactions were assessed 24 hours later. For intradermal induction application a 5% test article dilution was selected.
EPIDERMAL APPLICATIONS:
Both flanks of each of 4 guinea pigs were clipped and shaved just prior to the application. Thereafter 4 patches of filter paper (2 x 2 cm) were saturated with the test article at A = 75% (this concentration used was found to be the most qualified to assure an optimum technical application procedure), B =50 %, C = 25 % and D = 15 % of the test article in vaselinum album and applied to the clipped and shaved flanks. The patches were covered by a strip of aluminum foil and firmly secured by elastic plaster wrapped around the trunk and covered with impervious adhesive tape. This procedure ensured the intensive contact of the test article. The dressings were removed after an exposure period of 24 hours. 21 hours after removal of the dressing the application site was depilated with an approved depilatory cream (VEET Cream, Reckitt & Colman AG, CH-4123 Allschwil) to clean the application site from staining produced by the test article, so that possible erythema reactions were clearly visible at that time. The depilatory was placed on the patch sites and surrounding areas, and left on for 3-5 minutes. It was then thoroughly washed off with a stream of warm, running water. The animals were then dried with a disposable towel, and returned to their cages. The reaction sites were assessed 24 and 48 hours after removal of the bandage for erythema and oedema on a numerical basis according to Draize described below.

- Conclusions:

- Executive summary:
To assess the allergenic potential of FAT 21021/D in albino guinea pigs, the maximization-Test (B. Magnusson and A.M. Kligman (1969)) was followed in a GLP-compliant study. Ten females were used as control group and 20 females were used as test group.In addition to the sensitizing reactions the following observations and data were recorded during the test and observation period, they were Viability/Mortality, Clinical Signs, Skin reactions, Body Weights and Necropsy. As the test article stained the skin violet, it was not possible to determine whether erythema was present. However, no oedema was observed. No positive reactions were observed in the animals treated with vaselinum album alone. Seven and six out of 20 animals were observed with very slight to well defined erythematous reactions at the 24- and 48-hour reading respectively when treated with the test article at 25 % in vaselinum album. Violet discoloration was observed after removal of the dressing. As there were no deaths during the course of the treatment period no necropsies were performed. No symptoms of systemic toxicity were observed in the animals. Two out of 10 animals of the control group, two out of 20 animals of the test group and 3 out of 4 animals of the epidermal pretest lost weight during the acclimatization period. No loss of weight was observed during the treatment period. In this study 35 % and 30 % of the animals of the test group were observed with positive skin reactions after treatment with a non-irritant test substance concentration of 25 % in vaselinum album. No skin reactions were observed in the control group. The response of at least 30 % positive animals is considered positive following the "Commission Directive 93/21/EEC, April 27, 1993 adapting to technical progress for the 18th time Council Directive 67/548/EEC on the approximation of the laws, regulations and administrative provisions relating to the classification, packaging and labelling of dangerous substances". Therefore, the test article POLAR ROT RLS ROH TROCKEN (FAT 21021/D) at concentration of 25 % in vaselinum album is considered to be a sensitizer when described under the test conditions. According to the rating of allergenicity by Magnusson and Kligman the test article is a moderate sensitizer.

Justification for classification or non-classification
Acid Red 260 was found to have sensitising potential to the skin, hence it needs to be classified as skin sensitiser cat 1B according to the criteria set by Regulation (EC) No. 1272/2008.
