Lanolin is a complex material consisting of a mixture of numerous esters and polyesters of high-molecular-weight alcohols and fatty acids. Lanolin allergy is important because lanolin is widely used as an emulsifier in topical medicaments and in numerous cosmetic preparations. We report a case of allergic contact dermatitis in a 27-year-old female. An erythematous pruritic rash developed around the eyelid developed after applying a new eye cream and was aggravated after applying Cambison® ophthalmic ointment. Patch testing showed positive reactions to Cambison® ophthalmic ointment, 30% wool alcohol, Amerchol L101 and Nivea® cream. A use test with 100% Cambison® ophthalmic ointment base was positive.
