Lanolin is a naturally occurring wax found in wool fiber. It is cleaned out of the wool during processing the fibers for fabric and yarn. We only use the purest pharmaceutical grade lanolin. Lanolin conditions the wool fibers and gives the waterproof protection we love about wool. Lanolin also increases the wool’s anti-bacterial properties to help your diaper cover self-clean between uses and naturalize urine.
You may emulsify with shampoo or most soaps. We do not recommend glycerin because it attracts water, can can cause drying of the wool fibers as well as reduce the effectiveness of the lanolin.
