Skin sensitisation
Administrative data
- Endpoint:
- skin sensitisation: in vivo (non-LLNA)
- Type of information:
- experimental study
- Adequacy of study:
- weight of evidence
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study

Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: EPA 540/9-82-025
- GLP compliance:
- yes
- Type of study:
- guinea pig maximisation test
- Justification for non-LLNA method:
- The Guinea Pig Maximazitation Test met the previous requirements before the entry into force of REACH. The GPMT is suitable and reliable to cover this endpoint. For this reason and for animal welfare reasons, no further in vivo study (LLNA test) needs to be performed.

A. INDUCTION EXPOSURE
1st application: Induction 5 % intracutaneous
2nd application: Induction 25 % occlusive epicutaneous
B. CHALLENGE EXPOSURE
3rd application: Challenge 10 % occlusive epicutaneous
METHOD
Day 1 : Intradermal induction exposure (Injection): The injection sites were not covered.
Day 1-7: The application area was investigated.
Day 9 : Dermal induction exposure: 0.5ml of the test substance preparation were applied to a cellulose patch of 2x4 cm. This patch covered
the area of the intradermal injection sites. An occlusive dressing with impermeable foil and an elastic bandage sealed the application site for 48 hours.
Day 11 : Removal of the occlusive dressing. Recording of the irritation.
Day 22 : Dermal challenge exposure. 0.5ml of test substance preparation were applied to a cellulose patch and placed onto the clipped skin of the flank. An occlusive dressing with impermeable foil and an elastic bandage sealed the application site for 24 hours.
Day 23 : Removal of the occlusive dressing.
Day 24-25: Assessment of the skin.

- Remarks:
- Reading: other: 1st and 2nd reading. Group: test group. Dose level: ca. 76.5 mg. No with. + reactions: 2.0. Total no. in groups: 20.0. Clinical observations: 24 and 48 hours after removal of the occlusive dressing, very slight, hardly perceptible erythema .
Any other information on results incl. tables
1) The treated animals did not show any
signs of toxicity throughout the study period.
2) Induction: Very slight to slight edema were observed in the treatment
group.
3) Challenge: 24 and 48 hours after removal of the occlusive dressing, a
total of 2 animals (in 20) of the treatment group showed
very slight, hardly perceptible erythema.
Ten percent of the animals of treatment group demonstrated a positive
reaction after the challenge exposure
(the criteria: the limit value of 30 percent).
