Comments

Lanolin is a complex natural mixture of esters of alcohols and fatty acids present in sheep fleece. Wool that is manufactured to reduce free wool alcohols below 3% can be worn by lanolin-sensitive individuals. Lanolin is a common cause of allergic contact dermatitis in leg ulcer patients treated with topical medications containing lanolin.
