It is named after Joseph Lister, the father of American disinfection, which was founded in 1879 and was originally a brand of Pfizer in the United States, and was later acquired by Johnson & Johnson. Listerine was the first over-the-counter mouthwash brand to be recognized by the American Dental Association, and its launch opened up a new oral care product, "mouthwash", which has been the world's number one seller for many years.
 
Since its introduction to the market in 1914, Listerlin has adhered to its core function of sterilization, and the mouthwash uses plant essential oils as the main ingredient, which has aromatic and antibacterial properties. Compared to Dr. Case, Listerine has better antibacterial ability, and the essential oils are permeable enough to penetrate the plaque, which can help reduce plaque when combined with daily brushing.
 
The spicy and pungent taste is the first impression most people have of Listerin mouthwash, and the culprit is alcohol. The active active ingredients of essential oils in its formulation, such as menthol and eucalyptol, are not soluble in water and require alcohol as a solvent. Alcohol is one of the more commonly used solvents and is found in many cosmetic products. The advantage of using alcohol as the main solvent in mouthwash is that it does not destroy other ingredients and efficacy, and it has a certain bactericidal effect itself, which can increase the antibacterial effect.
 
The alcohol content of Listerine products is about twice that of general wine, and the lowest content is 21.6%, which is very irritating to the oral mucosa, which is an important factor that causes the spicy and irritating taste of Listerine mouthwash. In addition, because alcohol evaporation can take away saliva and cause dry mouth, alcohol-based mouthwashes are not recommended for people with dry mouth to avoid aggravating symptoms.
 
In recent years, Listerine has also launched an alcohol-free version of mouthwash, which has been marketed in many countries in Europe, America and Asia. The alcohol-free version uses propylene glycol as a solvent, and although it has a milder taste, propylene glycol is highly permeable to the skin and poses certain risks. Judging from the sales data, alcohol-free mouthwash is more popular among domestic consumers.
 
Initially, the main reason to attract consumers to buy mouthwash is its breath-freshening effect, and the mechanism of Listerine to remove oral odor is slightly different from that of Dr. Case, the former directly acts on bacteria, while the latter is to remove the conditions for bacterial growth, and the mode of action is different, but in the end, it can achieve the purpose of removing oral odor. Nowadays, people are no longer satisfied with a single function, and from the perspective of market demand, consumers are most concerned about the effects of anti-cavity, gum protection and whitening.
 
Listerine Mouthwash has launched products for anti-halitosis, anti-moths and whitening, among which the anti-halitosis mouthwash is a basic model, suitable for consumers who need fresh breath, and has four flavors: Zero, Orange, Cool and Ice Blue. Among them, the ice blue flavor is the most classic and best-selling one, and its alcohol content is the highest in listerine, reaching 26.9%, which will have a spicy taste and choking taste when used, but the long-lasting freshness effect is better. If you can't accept the impact in your mouth, you can choose a zero-degree mouthwash, the only non-alcoholic mouthwash among the four that has a milder taste.
 
Cavity-proof mouthwash is also one of the main products of Listerine, the series are fluoride-containing formulas, fluoride can make the tooth tissue easily dissolved by organic acid hydroxyapatite to form insoluble fluoroapatite, improve the tooth's corrosion resistance, in addition to the use of fluoride toothpaste in the morning and evening, the use of fluoride mouthwash after daily meals or snacks can help protect teeth. For adult mothproof, it is recommended to use green tea mouthwash, which has a high sodium fluoride content of 0.02%, does not contain alcohol, has a mild taste and is non-irritating, and has the refreshing feeling of green tea after rinsing, which is suitable for people who use it for the first time and do not like spicy and irritating feelings. If you are accustomed to irritating the taste, you can choose an alcohol-containing multi-effect mouthwash, which not only adds sodium fluoride (content of 0.01%), but also contains zinc ions, which has a more comprehensive care for the oral cavity and has a good effect on preventing plaque, tooth decay, dental calculus, etc.
 
Children's mouthwash is an alcohol-free fluoride formula, specially designed for children's tooth decay, and the taste is sweet raspberry, suitable for children's taste. This mouthwash is recommended for children over 6 years old, and younger children should use it with caution, mainly because the teeth are still developing, fluoride can damage the enamel on the surface of the teeth, resulting in incomplete enamel mineralization, resulting in dental fluorosis, making the entire tooth yellow, difficult to wash away. In addition, children are easy to swallow by mistake during use, and swallowing too much fluoride mouthwash can endanger health and even lead to acute poisoning.
 
Healthy Brightening Mouthwash is the only whitening mouthwash in Listerine, the effective whitening ingredients are tetrapotassium pyrophosphate and pentasodium tripolyphosphate, and its whitening effect relies on these two phosphorus-containing compounds to chelate calcium ions, thereby preventing pigmentation and removing pigmentation, and playing a role in whitening teeth. For tooth discoloration caused by pigment adhesion, choosing this product has a certain whitening effect. Like most of the main whitening mouthwashes on the market, it can't actually bleach, but it can help restore the teeth to their original color, just as teeth cleaning can't whiten teeth, if you want to really whiten your teeth, you can't achieve it with mouthwash alone, you need to use more professional methods.
 
The price of mouthwash is basically determined by the number of active ingredients, and most of the products are priced between 30-50 yuan, which is very cost-effective on the whole. In addition, Listerlin has also cooperated with Tmall to launch two floral mouthwashes, which are more popular with young female consumers than Listerlin's usual professional mint flavor.
