FDA is aware of various products that have made their way into the cosmetic market that were originally developed for use on horses and other animals. While many may believe "if it's good for a horse, then it should be good for me," consumers should be aware that FDA does not impose any rules on cosmetic products intended for use on animals. For example, companies that intend to have their product used only on animals are not required to list ingredients on the label. However, if products intended for use on animals are also intended for human use, they must comply with FDA regulatory requirements for cosmetics.
FDA has issued a warning letter about product labeling to one company that has marketed horse grooming products to humans. The Agency is continuing its investigation into this type of product.
