MAIN STUDY: 10 male and 10 female guinea-pigs (5 male & 5 female guinea-pigs for controls) - Details on study design:
- RANGE FINDING TEST:
2 male & 2 female guinea-pigs were closely shorn in the shoulder region using electric clippers followed by an electric razor. 0.1 ml of several dilutions of the test material (0.06, 0.2, 0.6, 2.0%) were injected intradermally on each side of the mid-line. The animals were examined on the following day to determine the maximum concentration that could be used in the main test without causing untoward toxicity.
The flank of each animal in further groups of 2 male and 2 female guinea-pigs, was further shorn. 0.3 ml dosis of several dilutions of the test material (10, 25, 60, 100%) were absorbed onto 16 cm2 Whatman No. 3 filter paper patches. The patches were applied to skin on the shorn flanks, covered by occlusive tape, and retained by elastic adhesive bandage for 24 hours. After removal of the patches and bandages the dermal test sites were examined for signs of irritation which were scored using a four point scale. The concentration selected for topical induction in the main test was that which just caused irritation and the concentration chosen for topical challenge was that which was just non-irritant.
MAIN STUDY:
A. INDUCTION EXPOSURE
The animals were closely shorn in the shoulder region using electric clippers followed by an electric razor: two rows of intradermal injections were made, one of either side of the mid-line, as follows:
test animals: anterior sites (0.1 ml of FCA); middle sites (0.1 ml of test material 0.6% in vehicle); posterior sites (0.1 ml of test material0.6% in 50:50 FCA/vehicle)
control animals: anterior sites (0.1 ml of FCA); middle sites (0.1 ml of vehicle); posterior sites (0.1 ml of 50:50 FCA/vehicle)
Freunds Complete Adjuvans (FCA) was prepared for use as a 50% v/v aqueous emulsion. One week after induction by intradermal injection, the same area of dorsal skin was shaven using electric clippers only. A 16 cm2 patch of Whatman No. 3 filter paper was moistened with 0.3 ml of the undiluted test material and placed over the sites of intradermal injections. The patches were covered with occlusive tape and held in place by elastic adhesive bandage for 48 hours. Similar patches of filter paper moistened with the vehicle alone were applied to the control group guinea-pigs. Any abnormal reactions to the induction procedure were recorded.
B. CHALLENGE EXPOSURE
Challenge was carried out 3 weeks after the intradermal induction. Hair was removed from one flank of all test and control animals by clipping and shaving. A 4 cm2 patch of Whatman No. 3 filter paper, moistened with 0.1 ml of 60% of test material, was placed on the shaven area, covered by occlusive tape and held in position by elastic adhesive bandage. After 24 hours the patches and bandages were removed and the challenge sites examined for any response. The response was scored using a four point scale. The result of the test is expressed as the number of positive responses shown by the test animals at 24 and/or 48 hours after removal of the challenge patches. the frequency of positive responses rather than their intensity is regarded as the important statistic in this test.

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- In the guinea-pig maximization test of Magnussen and Kligman none of the twenty test animals and 10 control animals showed a positive respons 24 or 48 hours after removal of the challenge patches.
- Executive summary:
Brake Fluid DOT 4 Super is considered to have a similar toxicological profile as B-TTEGME. Brake fluid DOT 4 Super (containing 76% B-TTEGME) was tested for sensitization in the guinea-pig maximization test of Magnussen and Kligman. In a dose range finding test in 2 male and 2 female guinea-pigs/group, 0.1 ml (0.6% in water) and 0.3 ml (undiluted test material) showed slight irritancy and were therefore selected for intradermal and topical induction for 48h, respectively. For challenge, 60% test material in water was applied under occlusive tape for 24h . None of the 10 male and 10 female test animals showed a positive respons 24 or 48 hours after removal of the challenge patches. None of the 5 male and 5 female control animals showed any response to application of the 60% test material in water.
