Each year, millions of animals are killed in laboratories. Cosmetic and household products and ingredients are not required to be tested on animals, and since non-animal alternatives exist, it is hard to understand why companies continue to animals in testing. There are tests that are more reliable and less expensive that don't require animals.
Companies can also use ingredients that have already been proven safe or natural ingredients.
Unfortunately, companies are still using outdated and cruel tests. The Draize Eye Irritancy Test is used to judge the ability of a test substance to cause damage to the eye. Substances are put in the eyes of conscious rabbits. In a typical test, rabbits are held in such a way that they can't use a paw to remove the substance from their eyes. Rabbits don't have tear ducts like humans do, so the substance is not 'washed' away.
