Northern Essence solid lanolin is made of high quality 100% pure natural lanolin. No preservatives or additives. Lanolin has been used for many years to hydrate very dry skin by easily absorbing into skin cells, chapped lips, nursing nipples and much more. Of course, it also works great to lanolize all your wool products. Has the look of a thick yellow butter with a natural lanolin scent. You can have it blended with Naural Essential Oils to add a natural scent. We highly suggest if you are using the lanolin with babies or for nursing nipples, that you use it plain in it's natural form.
