Study design: in vivo (non-LLNA)
Induction
- Route:
- epicutaneous, occlusive
- Vehicle:
- paraffin oil
- Concentration / amount:
- 75% (v/v) in paraffin oil for induction
- Day(s)/duration:
- three weeks
Challenge
- Route:
- epicutaneous, occlusive
- Vehicle:
- paraffin oil
- Concentration / amount:
- 25% (v/v) solution in paraffin oil challenge dose
- No. of animals per dose:
- 10 test, 5 control
- Details on study design:
- Ten male Hartley guinea pigs were treated once a week for three weeks with 0.4 ml of 75% test substance in paraffin oil.
Two weeks after final application, they were challenged with 0.4 ml of 25% test substance in paraffin oil.
Scores were taken at 24 and 48 hours.
A vehicle control group was tested using paraffin oil only; a naïve control group was tested in the challenge phase only; a positive control group was tested using dilute solutions of 2,4-dinitrochlorobenzene. - Challenge controls:
- A 25% (by volume) solution was used as a challenge dose
- Positive control substance(s):
- yes
- Remarks:
- 2,4-dinitrochlorobenzene
Results and discussion
- Positive control results:
- Evidence presented over a relevant time period that the strain of guinea pig did respond to known sensitisers.

Any other information on results incl. tables
White spirit (Stoddard solvent containing 14.5% aromatics) was found not to be sensitizing in a Buehler test. A 75% (by volume) solution of white spirit (Stoddard solvent) in a vehicle of paraffin oil used for the three sensitizing doses was found to induce mild to moderate irritation. A 25% (by volume) solution was used as a challenge dose.
