Traditional Use
Lanolin has been used since ancient times as a skin protectant and emollient in wool processing and traditional European skincare. The PEG-20 hydrogenated version was developed in the 20th century to make lanolin water-soluble and easier to incorporate into modern cosmetic formulations.
