Both problems are solved by buying your lanolin-based products from a reputable company; a company you know and trust; a company with visibility - a website with contact information; a detailed label on their product. make sure the lanolin in your lotion is labeled as pure grade, fine grade, highly refined, or medical grade. If you're unsure about the grade, email the company through their website. The well-refined lanolins will be free of pesticides and impurities.
When purchasing a finished skincare product, make sure, too, that it has not been tested on animals. The website my make up mirror has a list of companies that do not use animal testing, and this list is constantly being updated.
Lanolin itself is not likely to cause allergic reactions, although each individual must check with their doctor before using anything that is absorbed into the body.
Pure lanolin is obtained without harming the sheep - as opposed to emu oil, which is gathered by killing the bird. Lanolin is a near-perfect skin softener and emollient. many lanolin-based products are non-animal tested. And by making sure the soap, lip balm, skin cream, moisturizer, or hair product you use contains only high grade or medically graded lanolin, you can breathe easy, and enjoy lanolin's benefits.
