The Kookaburra Company is now manufacturing Kookaburra woolwash and sheepskin shampoo in America with an improved formula. We've added Lanolin to enhance the luster of the wool and handle of the sheep skin. Lanolin also imparts softness to all fibers washed with Kookaburra. The oil extracted from the leaves of the Australian Tea Tree (Melaleuca Alternifolia)is well known to be effective against dust mite, a cause of allergen for asthma sufferers, particularly infants. Tea Tree Oil is also noted for it's general beneficial qualities. A natural fungicide and bacteriostat, it also helps in the healing of wounds and reduces skin irritation. While Kookaburra woolwash and sheepskin shampoo was developed for sheepskin and woolen products, it's great for the laundering of bed linen, babies items and clothing for asthma sufferers where dust mite is a critical matter.
