Listerine is a brand of antiseptic mouthwash product. It is promoted with the slogan "Kills germs that cause bad breath". Named after Joseph Lister, a pioneer of antiseptic surgery, Listerine was developed in 1879 by Joseph Lawrence, a chemist in St. Louis, Missouri.

History

Listerine was originally formulated by Dr. Joseph Lawrence and Jordan Wheat Lambert. It was initially used as a surgical antiseptic and later as a floor cleaner. In 1895, it became the first over-the-counter mouthwash sold in the United States. The Lambert Pharmacal Company, which later became Warner-Lambert, began marketing Listerine as a cure for bad breath in the 1920s.

Composition

Listerine's active ingredients include menthol, eucalyptol, methyl salicylate, and thymol. These ingredients are known for their antiseptic properties. The mouthwash also contains alcohol, which acts as a solvent for the active ingredients and enhances their antibacterial activity.

Uses

Listerine is primarily used to reduce oral bacteria and plaque, and to prevent gingivitis. It is also used to freshen breath. The product is available in various formulations, including alcohol-free versions for those who prefer not to use alcohol-based products.

Effectiveness

Studies have shown that Listerine is effective in reducing oral bacteria and plaque. It has been endorsed by the American Dental Association for its ability to reduce and prevent gingivitis. However, it should not be used as a substitute for regular brushing and flossing.

Varieties

Listerine is available in several varieties, including:

• Listerine Original
• Listerine Cool Mint
• Listerine Freshburst
• Listerine Total Care
• Listerine Zero (alcohol-free)

Marketing

Listerine has been marketed through various advertising campaigns over the years. One of the most notable campaigns was the introduction of the term "halitosis" to describe bad breath, which helped to create a market for the product.

Safety and Side Effects

While generally safe for use, Listerine can cause a burning sensation in the mouth due to its alcohol content. Some users may experience dry mouth or irritation. It is recommended to follow the instructions on the label and consult a dentist if any adverse effects occur.
