Lanolin or wool wax is a versatile ingredient and was used medicinally in ancient times. Lanolin is the secretion from sebum glands of sheep and is formed on the surface of their skin. However, the animals have to be treated with pesticides to protect them from parasites. The problem here is that these pesticides accumulate in the wool wax and can later lead to strong allergic reactions in users. This motivated IOI Oleo GmbH to develop a plant-based, synthetic alternative: et voila, SOFTISAN® 649 has since enriched our portfolio and has, among other things, made a name for itself as a lanolin substitute in the pharmaceutical industry.
