Abstract
A method to wash wool containing lanolin and impurities includes the steps of providing a volume of an aqueous liquid at a temperature below a melting temperature of the lanolin, soaking the wool in the volume of the liquid, creating air bubbles in the liquid and allowing the air bubbles to pass through the wool to attach the impurities, removing the air bubbles and attached impurities from the volume, and separating lanolin from wool containing lanolin and impurities, along with the wool and lanolin obtainable by this method.
