Founded in 1927, Koujiekang is a registered trademark of a professional oral care brand originating from Germany, providing a full range of oral care products, including toothbrushes, tongue scrapers, concentrated toothpaste, etc. Oral Cleancare products are jointly developed with well-known scientific research institutes, and the concentrated mouthwash has been highly praised by the German consumer magazines Ökotest and Stiftung Warentest.
 
Concentrated mouthwash is a classic and best-selling mouthwash, with an excellent reputation. Like Listerine, Koujiekang Concentrated Mouthwash is also an alcohol-based formula, with a variety of plant essential oils as effective antibacterial ingredients, which can effectively reduce the production of plaque, plant fragrance can remove oral odor, make breath fresher, and the xylitol content can also strengthen teeth and reduce the incidence of tooth decay. Although the product contains alcohol, it does not have the expected irritation, the taste is cooler, the formula does not contain preservatives and colorings, it is safer, and it is also suitable for pregnant women, and it is better than Listerine in terms of taste and safety.
 
The product is a concentrated formula that needs to be diluted to use, and only one drop of 15mL of water is added at a time, and the amount can be adjusted to your taste preference. The price of a single bottle of 50mL and 25mL is 89 yuan and 59 yuan respectively, which is easy to carry and cost-effective.
 
In addition to the classic models containing alcohol, Koujiekang has also launched a variety of antibacterial mouthwashes without added alcohol. EFFEKTIV Classic antibacterial mouthwash is mainly anti-cavities, containing cetylpyridine chloride, which is commonly used in mouthwash products, and adding xylitol and fluoride to prevent tooth decay. Another antibacterial mouthwash for gum care, EFFEKTIV Gingival, is formulated with CPC, allantoin, provitamin B5 and vitamin E to help relieve inflamed and bleeding gums, and also contains fluoride to prevent decay. These two antibacterial mouthwashes are non-concentrated, 550mL is priced at 119 yuan, and the one-time dosage is 20mL, which is not as cost-effective as concentrated mouthwash, but it is an alcohol-free formula, and the entrance is milder than concentrated mouthwash, with a fresh mint flavor that can keep the breath fresh.
 
Another antibacterial mouthwash, ONDROHEXIDIN, is a powerful version of EFFEKTIV Classic, which contains not only xylitol and fluoride as dual anti-caries ingredients, but also chlorhexidine gluconate and cetylpyridine chloride (CPC), which have a long-lasting antimicrobial effect and effectively prevent the formation of plaque and tooth decay. Alcohol-free formula, fennel mint flavor, mild and non-irritating, it is suitable for people with irritated gums or sensitive teeth, but the product is not recommended for long-term use, excessive use of mouthwashes containing chlorhexidine gluconate ingredients are prone to oral mucosal surface, tooth coloring, tongue coating blackening and other phenomena, and even affect the sense of taste.
 
Koujiekang products have excellent antibacterial properties, but their performance in anti-dry mouth is average. The PHARMACIA mouthwash is a product for relieving dry mouth, but if it is intended to be used to treat dry mouth, the effect is not as ideal as Dr. Case, the formula only contains xylitol and aloe vera moisturizing ingredients, which can only play a single role in moisturizing the mouth, but cannot solve the problem of saliva reduction and maintenance of saliva components. If you only occasionally feel dry mouth, you can choose to apply it, the moisturizing effect is not bad.
 
Unfortunately, at present, except for concentrated mouthwash, the other four products have no purchase channels in China.
