Cetylpyridinium chloride (CPC) is a quaternary ammonium salt antiseptic that is used in many over-the-counter personal-care products: mouthwashes, toothpastes, lozenges, and breath and nasal sprays, to name a few. It is also used in topical anti-infective products and as a pharmaceutical preservative.
