Results and discussion
- Positive control results:
- - Test material:
ALPHA-HEXYLCINNAMICALDEHYDE, TECH. 85% (CAS no. 101-86-0) was fabricated under lot no. 80281 and the purity was 99.4% (GLC) (Aldrich Chemicals Co., Germany).
- Results: The skin reactions in the experimental animals observed in response to the 50% and 25% test substance concentrations in the challenge phase were considered indicative of sensitisation, based on the absence of any response in the control animals.
These results lead to a sensitisation rate of 100 per cent for the 50% concentration and to a sensitisation rate of 60 per cent for the 25% concentration.
From these results, it was concluded that the Albino Dunkin Hartley strain of guinea pig is an appropriate animal model for the performance of studies designed to evaluate the sensitising potential of a substance in a Maximisation type of test.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Remarks:
- Migrated information
- Conclusions:
- 24 h respectively 48 h after challenge, the test and control animals did not show specific primary skin irritations or a reference to a specific sensitive effect. The test material FeEDDHMANa should not be classified as sensitizing to the skin.
- Executive summary:
A Guinea Pig Maximisation test was conducted with a group of 10 Dunkin Hartley guinea pigs and a negative control group of 5 Dunkin Hartley guinea pigs. They were used to investigate the skin sensitising properties of the FeEDDHMANa (trade name Bolikel FE). The study was performed in accordance with the method of B. Magnusson and A. M Kligman (OECD-guidelines: Guideline 406 ‘Skin Sensitisation’). The study was designed and performed according to Good Laboratory Practice Standards.
The test group received first intradermal injections with 5% test substance. After 7 days a topical application of 10% SDS in vaseline was performed. On Day 8 the animals were treated with a 48 h occlusive epicutaneous application of 50% concentration in distilled water. Two weeks after the last application, the test animals received a 24 h occlusive epicutaneous application (concentrations 50%, 25%, 10% and 0%). After 24 h and 48 h skin reactions were scored. Controls were treated with vehicle (distilled water) during induction and similar as the treated group during challenge.
No clinical signs and no deaths were noted during the study.
After the induction phase some skin effects were seen, like brown staining of the skin, small scabs, erythema and necrosis. The reactions were considered to be enhanced by SDS treatment.
After the challenge application, a discrete erythema was recorded in 1/10 animals of the 25% treated group at the 24- and 48-hour reading. The response to the 25% concentration was considered non-specific, since no response was observed to the higher concentration (50%) in this animal. No skin reactions were evident in the control animals.
24 h respectively 48 h after challenge, the test and the control animals did not show specific primary skin irritations or a reference to a specific sensitive effect. The test material FeEDDHMANa should not be classified as sensitizing to the skin.
