- RANGE FINDING TESTS:
Determination of the primary non-irritant concentration:
The following test concentrations were administered to the flanks of two guinea pigs:
25.0 % in Tylose H 4000 G4 PHA (0.5 % in deionized water)
5.0 % in Tylose H 4000 G4 PHA (0.5 % in deionized water)
1.0 % in Tylose H 4000 G4 PHA (0.5 % in deionized water)
0.5 mL of the test substance preparation was administered to a 2 x 2 cm cellulose patch, which was fixed to the flank and covered occlusively for 24 h with a bandage and film. 24 h after removal of the patches, the treated skin areas were examined for erythema and edema.
Determination of the tolerance of the intradermal injections:
The following preparations were administered twice by intradermal injection to 2 guinea pigs:
Site 1. 2X0.1 mL 5.0 % in Tylose H 4000 G4 PHA (0.5 % in deionized water)
Site 2. 2X0.1 mL 1.0 % in Tylose H 4000 G4 PHA (0.5 % in deionized water)
Site 3. 2X0.1 mL 0.2 % in Tylose H 4000 G4 PHA (0.5 % in deionized water)
24, 48, 72 and 96 h after administration the injection sites were examined for local tolerance.

OTHER:
The substance is considered to be sensitizing if 30 % or more of the animals in the treatment group definitely showed a positive skin reaction and at the same time no irritant effects have emerged in the control group. - Positive control substance(s):
- yes
- Remarks:
- Alpha-hexyl cinnamic aldehyde
Results and discussion
- Positive control results:
- Alpha-hexyl cinnamic aldehyde was skin sensitiser and proved to be suitable for the determination of dermal sensitizers

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the test conditions, the test substance showed no evidence for sensitizing properties in guinea pigs.
- Executive summary:
A study was conducted to assess the sensitizing potential of the test substance in female Pirbright-White guinea pigs (Magnusson & Kligman method) according EU Method B.6. and OECD guideline 406 in compliance with GLP.
Intradermal induction was performed using 5 % test substance in Tylose H 4000 G4 PHA (0.5 % in deionized water). Dermal induction and challenge treatment were carried out with 25 % test substance in Tylose H 4000 G4 PHA (0.5 % in deionized water).
The validity of the test system is confirmed by the periodically conducted positive control test using alpha-hexyl cinnamic aldehyde for the maximization test.
Under the test conditions, the test substance showed no evidence for sensitizing properties in guinea pigs.
