EC number: 271-363-2 | CAS number: 68551-11-1 A complex combination of products produced by the distillation of products from the hydrogenation of butanal from the hydroformylation of propene. It consists predominantly of organic compounds such as aldehydes, alcohols, esters, ethers and carboxylic acids having carbon numbers in the range of C4-C32 and boiling in the range of approximately 143°C to 282°C (289°F to 540°F).

- RANGE FINDING TESTS:
To obtain the appropriate concentrations of the test item for the definitive study, a pretest was carried out with 3 female guinea pigs. 4 different concentrations of the test item were administered epicutaneously. The mode of application was the same as in the definitive study. The duration of the epicutaneous exposure was 6 hours. The test item was applied as is (100 %) and diluted with acetone (75, 50, and 25%; v/v). For evaluation, skin findings were read 24 and 48 hours after removal of the patch. The following concentrations for induction and challenge were selected on the basis of the pretest: 1st, 2nd and 3rd induction: Test item as is (100%); 1st challenge: Test item as is (100%);
MAIN STUDY
A. INDUCTION EXPOSURE
- No. of exposures: 3
- Exposure period: 6 h
- Amount applied: 0.5 ml of the test item was applied to each animal.
- Occlusive dressing: The test patches (Pur Zellin-Tupfer, Fa. Hartmann, Wiener Neudorf, Austria, ca. 2 cm x 2 cm) were fully loaded with the test item, applied to the skin and fixed with a strip of Fixomull stretch (self adhesive non woven fabric, hypoallergenic, made by Beiersdorf AG, Hamburg, Germany). Occlusion was obtained by covering with teflon foil which was fixed with Guinea Pig Jacket (Hugo Sachs Elektronik- Harvard Apparatus GmbH, March-Hugstetten, Germany).
- Site: Left flank anterior.
- Frequency of applications: Three times at weekly intervals; on days 0, 7 and 14 on the same application site
- Concentrations: 100%
- Readings: 24 h after the beginning of the induction exposure.
The control group was treated analogously to the test group but only with highly deionized water.
B. CHALLENGE EXPOSURE (14 days after the last induction)
- No. of exposures: 1
- Amount applied: 0.5 mL of the test item was applied to the posterior right flank of each animal of each group. Additionally 0.5 ml of highly deionized water was applied to the anterior right flank as a control.
Occlusive dressing: The test patches (Pur Zellin-Tupfer, Fa. Hartmann, Wiener Neudorf, Austria, ca. 2 cm x 2 cm) were fully loaded with the test item or with highly deionized water, applied to the skin and fixed with a strip of Fixomull stretchm (self adhesive non woven fabric, hypoallergenic, made by Beiersdorf AG, Hamburg, Germany). Occlusion was obtained by covering with teflon foil which was fixed with Guinea Pig Jacket (Hugo Sachs Elektronik- Harvard Apparatus GmbH, March-Hugstetten, Germany).
- Day(s) of challenge: 1
- Exposure period: 6 h
- Site: Right posterior (test item) and right anterior (highly deionized water) flank.
- Concentrations: 100%
- Evaluation (hr after challenge): 24 and 48 h after the removal of the patch. - Positive control substance(s):
- yes
- Remarks:
- (see: Results and Discussion)
Results and discussion
- Positive control results:
- A positive control with a known sensitizer is not included in this study. A separate study is performed twice a year. The positive controls with Alpha-Hexylcinnamaldehyde, techn. 85% showed that the test system was able to detect sensitizing compounds.
