Application

Lanolin was used to compose the lanolin ointment to estimate the release kinetics of izotretinon and heparin from various semisolid dosage forms by UV-VIS spectroscopy. It was used to prepare the emulsified aqueous solutions containing crystalline dicarboxylic acid. It may be added as excipient to compose a nanoscale-dispersed eye ointment (NDEO) for the treatment of severe evaporative dry eye.

General description

Lanolin is a wool fat. It is a semisolid of high viscosity. Contact allergy to lanolin (wool alcohols), an important sensitizer, in a central London teaching hospital patch-test population has been reported. Simplified extraction of organochlorine and organophosphorus pesticides, frequently found in lanolin, has been proposed. It is utilized as an emulsifier in pharmaceutical and cosmetic formulations.
