Which term does NOT include soap in its definition according to cosmetic regulations?

The term that does not include soap in its definition according to cosmetic regulations is "cosmetic." In the context of U.S. regulatory definitions, a cosmetic is generally defined as a product intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering appearance. This definition does not specifically encompass soap, though soap can be considered a cosmetic if it is intended for those purposes.

In contrast, other terms such as "component," "Class II Device," and "combination product" relate to broader categories of items, which may include various formulations or products used in healthcare or cosmetic applications. A "component" can refer to any ingredient or part of a product, "Class II Device" includes medical devices that may have intended uses overlapping with cosmetic functions, and "combination product" refers to products that combine a drug, device, and/or biological product. However, these categories do not specifically isolate the definition in a way that excludes soap.

Thus, the distinction lies in how the definition of 'cosmetic' is structured under regulatory guidance, which allows for soap-like products to be classified differently based on their intended use or claims.
