C. This section shall not apply to any manufacturer or contract test facility using an animal test method for the purpose of medical research related to the causes, diagnosis, treatment, control, or prevention of physical or mental diseases and impairments of humans and animals, or related to the development of devices or drugs, as those terms are defined in 21 U.S.C. § 321, biomedical products, or any other products regulated by the U.S. Food and Drug Administration, except for any product regulated under Subchapter VI of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. § 301 et seq.). Such medical research does not include the testing of an ingredient that (i) was formerly used in a drug; (ii) was tested for use in a drug using commonly accepted animal testing methods to characterize the ingredient and to substantiate its safety for human use; and (iii) is proposed for use in a product other than a biomedical product, medical device, or drug.
