- Control group:
Vehicle control: The left flank was treated with the test item (10% concentration in aqua ad iniectabilia), the right flank with the vehicle i.e. in the same way as the test group.
Positive control: The filter paper containing 0.01% α-hexyl cinnamic aldehyde solution was applied to the left flank, the filter paper with the vehicle to the right flank of the animal.
- Site: Flanks
- Concentrations: 10% suspension of the test item in tap water
- Evaluation (hr after challenge):
21 hours after removing the filter paper the challenge area was cleaned and cleared of hair if necessary; three hours later (at 48 hours from the start of challenge application) the skin reaction was observed and recorded; 24 hours after this observation a second observation (72 hours) was made and recorded.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the present test conditions, test item containing 39.80% active ingredient, was found to be not sensitising to guinea pigs in a test model according to MAGNUSSON and KLIGMAN.
- Executive summary:
The purpose of this study was to determine the potential of the test item, containing 39.80% active ingredient, in guinea pigs in a test model according to MAGNUSSON and KLIGMAN.
From a preliminary experiment, it was decided to use a 0.5% concentration in aqua ad iniectabilia for the 1st (intracutaneous) stage, a 25% suspension in aqua ad iniectabilia for the 2nd (topical) induction stage and a 10% suspension in aqua ad iniectabilia for the challenge.
A 0.5% suspension in aqua ad iniectabilia chosen for the 1st (intracutaneous) induction stage revealed a discrete or patchy erythema in all 10 animals 24 and 48 hours after administration. 2 mL of a 25% suspension of the test item in aqua ad iniectabilia/animal chosen for the 2nd (topical) induction stage revealed a moderate and confluent erythema 48 hours and a discrete or patchy erythema 72 hours after start of exposure in all 10 animals. The challenge with 2 mL of a 10% suspension of the test item in aqua ad iniectabilia /animal - the maximum non-irritating concentration - revealed no skin irritation in any animal and, thus, the test item had no sensitising properties.
The vehicle control revealed no skin reactions.
Animals of the same strain treated with α-hexyl cinnamic aldehyde in sesame oil exhibited a sensitising reaction in all animals in form of a moderate and confluent erythema (grade 2).
Behaviour of the animals remained unchanged. Body weights were not affected
Under the present test conditions, test item containing 39.8% active ingredient, was found to be not sensitising to guinea pigs in a test model according to MAGNUSSON and KLIGMAN.
