Purelan™ formulation has been developed to minimize its allergenic potential. Carefully controlling the levels of FLA (free lanolin alcohols) in lanolin can reduce skin reactions even among those who are already sensitive to lanolin. Research shows that reducing the FLA content to less than 3%, particularly when detergent residues have been removed from the product, reduces the incidence of positive patch-test reactions among lanolin-sensitive skin patients. With an alcohol fraction of less than 3% in Purelan, the allergenic potential to lanolin alcohols, which is observed rarely, is reduced to an absolute minimum as per EP (European Pharmacopeia).
Purelan does not contain other additives that might cause a reaction, such as preservatives and fragrances.
Additionally, Purelan is dermatologically tested. However, anyone with a known lanolin allergy should avoid using lanolin products, including Purelan.
