- TREATMENT AND OBSERVATION METHODS:
Patching Method: The same patching method was used for induction, irritation screens, challenge and re-challenge. The animal’s fur was shaved on the day before exposure with a fine clipper blade. Closed patches were applied to the animals as follows: A 25 mm Hill Top Chamber was saturated with the test article dilution which was applied with a spatula. Animals were put in the restrainer and the designated patch was applied to the clipped surface as quickly as possible after the test substance had been applied. The patch appliance was occluded with a rubber dental dam. The rubber dental dam used for occlusion of the patches was of medium gauge 12 - 15 cm wide, depending on the animal size and the number of patches to be covered. The rubber dental dam was pulled snug on each side of the animal and secured with one or more large size clip on each side of the restrainer. The rubber dental dam was placed under the front and back metal restraining bands and had snug contact with the animal over the entire dorsal surface. The restrainers were adjusted to minimize movement of the animals during the exposure period. Six (6) hours (+ 15 minutes) later, the rubber dental dams and patches were removed, and the animals were taken away from the restrainers. After that the animals were returned to their individual cages.
GRADING METHOD:
The animals used for irritation screens and challenge were depilated eighteen to twenty-two (18 - 22) hours after patches had been removed, using an approved depilatory cream (VEET Cream, Reckitt & Colman AG, CH-4123 Allschwil). 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. Erythema and edema were assessed as follows:
ERYTHEMA
0 = no erythema
+ = slight, patchy erythema (i.e barely perceptible or questionable reaction)
1 = slight confluent erythema (i.e., a slight but definite reaction at the patch site) or moderate, but patchy erythema (i.e., moderate erythema involving at least 50% or more of the area of the patch site)
2 = moderate confluent erythema
3 = severe erythema
OEDEMA (according to Draize)
0 = no edema
1 = very slight edema (barely perceptible)
2 = well-defined edema (edges of area well-defined by definite raising)
3 = moderate edema (raised approximately 1 millimeter)
4 = severe oedema (raised more than 1 millimeter and extending beyond the area of exposure)
The grading method used for irritation screens, induction and challenge was identical. This one was performed 24 hours (+ 2 hours) after removal of the patches for the irritation screens, induction and challenge and repeated 24 hours (+ 2 hours) later (48-hour grades) for irritation screen and challenge. The grading method used for re-challenge and challenge was identical.
NOTE:
(1) At challenge and re-challenge, control animals were graded before the test animals. Grading of all animals was done by positioning the animal under true light (Osram, 58-Watt, light quality TLD). Grading was done by two (2) technicians, who both agreed to the recorded score. Comparison of sites on other animals in the test or control groups was required to arrive at a final score.
(2) To monitor skin reactions during the induction phase, the skin was graded without depilation. - Positive control substance(s):
- yes
- Remarks:
- 0.5 % 1-chloro-2,4-dinitrobenzene in ethanol

PRIMARY SENSITIZATION RESULTS (INCIDENCE TABLES)
CHALLENGE / Erythema Readings:
Induction Concentration (test group only): 25 % POLAR BLAU RLS (FAT 21036/D) in vaselinum album
Challenge Concentration (control & test group): 25 % POLAR BLAU RLS (FAT 21036/D) in vaselinum album
Grade of 0 and + are considered to be representative of insignificant responses, whereas those of 1 or greater are considered to be significant. In this study 42 % of the test animals were observed with significant response at either 24 or 48-hour challenge reading. The response of at least 15 % positive animals is considered positive "R43" following the commission 93/21/EEC, Commission Directive of 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 substance POLAR BLAU RLS (FAT 21036/D) tested in concentration of 25 % in vaselinum album is considered to be a sensitizer.
MORTALITY / VIABILITY / MACROSCOPIC FINDINGS: One animal (no. 652) of the control group was found dead on test day 28. At necropsy, a dark red discoloration of the uncollapsed lungs was observed as well as several dark red foci (D = 5mm). One animal (no. 678) of the test group was found dead on test day 1. At necropsy the lungs were not collapsed with several dark red foci (D = 4mm).
CLINICAL SIGNS (LOCAL/SYSTEMIC): Neither local nor systemic symptoms were observed during the study.
BODY WEIGHTS: Two animals of the control group and one animal of the test group lost weight during the acclimatization period. The lost of weight should be considered to be of incidental nature.

Applicant's summary and conclusion
- Interpretation of results:
- Category 1B (indication of skin sensitising potential) based on GHS criteria
- Conclusions:
- FAT 21036/D was found to be a skin sensitizer.
- Executive summary:
A key study was performed to assess the possible allergenic potential of FAT 21036/D when administered to the skin of albino guinea pigs. For this purpose the "Buehler-Test" modified by Ritz, H. L. and Buehler, E. V. (1980) was used. Methodlogy was according to OECD test guideline 406 under GLP conditions. Ten females remained untreated and were used as control animals to be treated at challenge. Twenty test females were induced three times during induction and challenged with the test substance. Induction Concentration (test group only): 25 % FAT 21036/D in vaselinum album. Challenge Concentration (control & test group): 25 % FAT 21036/D in vaselinum album. Grade of 0 and + are considered to be representative of insignificant responses, whereas those of 1 or greater are considered to be significant. In this study 42% of the test animals were observed with significant response at either 24 or 48-hour challenge reading. No local or systemic symptoms were observed during the study. The response of at least 15 % positive animals is considered positive "R43" following the commission 93/21/EEC, Commission Directive of 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 substance FAT 21036/D tested in concentration of 25 % in vaselinum album is considered to be a sensitizer.
