Listerine is an American brand of oral care products that has evolved from an early surgical antiseptic into a global household staple, known primarily for its antiseptic mouthwash. The brand is currently owned and manufactured by Kenvue, a consumer health spin-off from Johnson & Johnson. Company Overview and History Origin: The original formula was developed in 1879 by Dr. Joseph Lawrence, a chemist, and named after Sir Joseph Lister, a pioneer of antiseptic surgery. The formula was licensed to the Lambert Pharmacal Company in 1881. Ownership: The brand has changed hands several times through corporate acquisitions (Warner-Lambert, Pfizer, Johnson & Johnson). As of 2023, it is a key brand within the Kenvue portfolio. Kenvue is expected to be acquired by Kimberly-Clark in late 2026. Transformation: Listerine was initially marketed to medical professionals and was slow to gain public traction. Its commercial success exploded in the 1920s due to innovative and memorable advertising campaigns that framed "bad breath" as the medical condition "halitosis," creating a social need for the product. Products and Efficacy Listerine is a leader in the oral care market, dedicated to advancing oral health through scientific research and innovation. Its products are widely available in various formulations: Core Products: Includes a range of mouthwashes, toothpaste, and other oral care solutions. Key Ingredients: The original antiseptic mouthwash contains a fixed combination of four essential oils (eucalyptol, menthol, methyl salicylate, and thymol) that are clinically proven to kill germs that cause plaque, gingivitis, and bad breath.
