Listerine is a professional oral care brand, named after Joseph Lister, the father of American disinfection, founded in 1879, originally a brand of Pfizer in the United States, and later acquired by Johnson & Johnson. Listerine was the first over-the-counter mouthwash brand to be recognized by the American Dental Association and has maintained the world's No. 1 sales volume for many years, with breath fresheners being its second-largest selling category. Since its introduction to the market, Listerine's breath freshener has been sterilized with plant essential oils as the main formula, which has aromatic and antibacterial properties. Compared to Dr. Case, Listerine has better antibacterial ability, and the essential oils can penetrate into the plaque, which can help reduce plaque when combined with daily brushing.
 
Listerine's Breath Freshener comes in two flavors, one ice blue and one cool. The product contains acesulfame potassium and galactose with a sweet taste, this sugar substitute is a widely used sweetener that is not broken down by bacteria and does not cause tooth decay.
 
The spicy taste is the first impression that most people have of listerine mouthwash and breath freshener, because the solvent component is alcohol, which is used to dissolve the effective ingredients such as menthol and eucalyptol in the formula, and it also has a certain bactericidal effect. Alcohol is irritating, but it does not cause harm to the body. Because of the alcohol component, you may not pass the breathalyzer test just after spraying, but the breath alcohol level will return to normal after 10 minutes.
 
Listerling's breath freshener is designed like a key charm, and compared to a bulky bottle of mouthwash, the oral spray can be carried with you at any time. The bottle mouth adopts an integrated design, so you don't have to worry about losing the cap, and the hidden spout can avoid pollution, a 7.7ml can be sprayed 140 times, and the price is 25 yuan.
