Allergy to lanolin.


The purpose of the present study was to compare the frequency of lanolin allergy during two periods and to assess the adequacy of testing with one standard allergen. Among 1230 consecutive patients with eczema who were standard patch tested, 33 (2.7%), 21 females and 12 males, gave a positive reaction to wool alcohols. Among 899 consecutive patients with eczema standard patch testd and also tested with the lanolin derivatives hydrogenated lanolin 30% in soft yellow paraffin, Amerchol L 101, and a mixture of lanolin derivatives, 60 patients (6.6%), 48 females and 12 males, gave a positive reaction to lanolin and/or its derivatives. The results show that testing with one standard lanolin allergen is inadequate for detecting lanolin allergy.
