Originally located in the Penfield, NY area and now headquartered in Smithville, MO, Thornell has always been a family owned business and we take great pride in the products we manufacture. The totally unique chemistry that makes Thornell products, including Odorcide 210, so effective was originally developed during a test at Cornell University in the late 1970's. Since that time Thornell's line of products sold in the veterinary field have grown in popularity every year and to this date Thornell is America's premier supplier of odor elimination products to veterinarians all across North America. Thornell Corporation's sole business is manufacturing odor elimination products. You can rest easy knowing that if you are using Thornell products, you are in fact using, "The One That Works!".
