Lanolin has the reputation of being an important contact sensitizer. T
he market place abounds with products that are labeled ''lanolin free'
'. In fact, lanolin is at most a weak contact allergen. The supposed h
azards of sensitization to lanolin products are a resultant of faulty
science and failure to appreciate the limitations of patch testing. La
nolin allergy is a myth created mainly by overzealous professional pat
ch testers. No one has succeeded in sensitizing animals or humans to l
anolin or wool wax alcohols. Most of the case reports are false positi
ves, in association with the angry back syndrome.
