Inactive Ingredient description

The list of inactive ingredients is the part of an over-the-counter Drug Facts label required by regulatory agencies in the United States on such products as sunscreens and anti-blemish products that contain benzoyl peroxide or salicylic acid. Inactive ingredients must be listed alphabetically or can be listed in descending order of concentration. “Inactive” does not mean the ingredients don’t have any effect; rather, it simply means they do not have regulatory status as active ingredients. On OTC drug products, inactive ingredient labeling must follow regulatory guidelines set forth in the official International Cosmetic Ingredient Dictionary.
