Type of sensitisation studied:
skin
Study type:
study with volunteers
Principles of method if other than guideline:
RM-Freetext: method: pretreatment (no data if this was necessary for the TS because of the suspected irritation) with 5% sodium lauryl sulfate for 24 h (inflammatory reaction promote sensitization); occlusive allergen patches for induction with 5% TS solution for 48 h; repetition of both four times; challenge patch for 48 h; challenge concentration 0.5%; evaluation 0 and 48 h after removing the patch.
GLP compliance:
no
