What is Lanolin?
Lanolin is a waxy substance secreted by the glands of wool-bearing animals. Most lanolin we use comes from domestic sheep. Lanolin's role in nature is to protect wool and skin against the climate and the environment. It is therefore not surprising that lanolin and its derivatives are often used in products designed to protect, treat and beautify our skin. Many of the personal care products we use each day contain lanolin such as shampoos, shaving creams, moisturizers, eye makeup, lipstick, sunscreen and more.

Why is it Harmful?
Lanolin itself is perfectly safe. However, cosmetic-grade lanolin can be contaminated with carcinogenic pesticides such as DDT, dieldrin, and lindane, in addition to other neurotoxic pesticides. Livestock owners routinely use insecticide on sheep because they are susceptible to pests. Any chemicals used on sheep will contaminate the lanolin obtained from the wool. Studies have found that lanolin samples can contain many types of pesticide residues. Some of the identified pesticides could potentially accumulate in fat tissues, and breast-feeding women may have their milk contaminated by these residues.

Lanolin poisoning is another concern. Swallowing products that contain lanolin can be harmful. Signs of lanolin poisoning may include diarrhea, vomiting, rash, skin redness and swelling. As well, eating large amounts of lanolin can cause an intestinal blockage. If your child or someone else has swallowed a product containing lanolin, seek medical attention immediately.

How to Protect Yourself
Be careful when choosing personal care products and avoid those containing lanolin. Though it is an effective moisturizer, you can find great lotions that work just as well and are natural too! Look for vegan products that are animal product free. Check out the beauty products you use on a day-to-day basis on EWG’s Skin Deep Cosmetics Database to ensure they do not contain lanolin.
