- No. of animals per dose:
- 20 animals with test substance, 10 animals with negative control (water), 5 animals with DNCB positive control and 5 animals with irritation control for DNCB (olive oil).
- Details on study design:
- First induction (intradermal injection): An area of 4 x 6 cm on the scapular region was clipped. The next day 0.1 ml of each dosing formulation were injected intradermally into sites 1, 2, 3, 1', 2' and 3'. The formulations are as follows:
- Injection sites 1, 1': Water/FCA
- Injection sites 2, 2': Test substance group (1 w/v% test substance solution); Control group for test substance (water for injection); DNCB group (0.05 w/v% DNCB/olive oil); Control group for DNCB (olive oil).
- Injection sites 3, 3': Test substance group (1 w/v% test substance solution/FCA); Control group for test substance (water/FCA); DNCB group (0.05 w/v% DNCB/FCA); Control group for DNCB (Water/FCA).
Second induction (topical application): Six days after the initial induction, the skin of the induction area was clipped again and 0.5 ml of 10% sodium lauryl sulphate in white petrolatum was spread over the area covering the injection sites. Seven days after the initial induction, 0.2 ml of each dosing formulation (as above) was spread onto a 2 x 4 cm cotton flannel patch and applied to the injection area. This patch was covered with a 5 x 10 cm elastic adhesive bandage back with a 5 x 5 cm polyethylene tape and firmly secured with a 5 x 40 cm elastic adhesive bandage. These patches were removed after 48 hours of their application.
Challenge: The test animals were challenged 21 days after the initial induction. One day before the challenge, the challenge site (4 x 4 cm area) was clipped free of hair. The next day, 0.1 ml of dosing formulation (same as those used in the initial induction) were spread onto a 2 x 2 cm cotton flannel patch and applied to the challenge sites. These patches were covered with an impermeable sheet and secured with a 5 x 70 cm elastic adhesive bandage. These patches were removed 24 hours after the application. - Challenge controls:
- 10 animals given water only at induction
- Positive control substance(s):
- yes
- Remarks:
- DNCB
Results and discussion
- Positive control results:
- 100% sensitisation. All animals displayed intense erythema and swelling.

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- Under the conditions of this study, allyl alcohol is not considered to be a skin sensitiser.
- Executive summary:
Guinea pigs (20 in a test group, 10 negative controls plus positive controls) used in a maximization test (OECD guideline 406). The positive control material used was DNCB. No allyl alcohol treated animals displayed any skin reaction and no clinical effects were observed.
In this study, allyl alcohol did not cause dermal contact sensitisation.
