Binas is a subsidiary of Pieras Co., Ltd., which was founded in 1980 and focuses on cosmetics and takes the route of high quality and low price. Bina's mouthwash became famous in China because it appeared on Faye Wong's washstand, and was sought after by many consumers because it can gargle "visible dirty things".
 
Different from the antibacterial principle of traditional mouthwash, Bina's mouthwash uses malic acid and citric acid to remove a layer of obsoletic film and its attachments attached to the tooth surface, directly cutting off the hotbed of bacterial breeding and achieving the effect of antibacterial. In addition, the high acidity is the characteristic of Bina mouthwash, which denatures and solidifies the proteins in the mouth, and the flocculent material can be seen when rinsing out, giving a feeling of a clean mouth on the surface, but the actual effect is not as immediate as advertised.
 
Propolis Compound Mouthwash is one of Bina's most classic products, and has been on the list of Japan COSME Awards. Compared with general antibacterial mouthwashes, propolis compound mouthwashes are not excellent in antibacterial and oral odor removal, but they are not bad for oral cleaning. The product is an alcohol-containing formula, with a cool taste and a sour taste, so people with sensitive teeth should use it with caution.
 
In addition, Binar's has also launched a number of limited editions, and the formula is slightly adjusted on the basis of the propolis compound mouthwash. Sakura-limited Propolis Mouthwash is one of them, and it has the same effect as the classic model, but it is alcohol-free and has a milder taste. If you are accustomed to the taste of alcohol-based mouthwashes, you will have more options in terms of flavors, and the limited flavors such as matcha, yuzu, tangerine, and lemon are all alcohol-based formulas.
 
The other two mouthwashes emphasize whitening and freshening the breath, and the results are not outstanding, but they are also remarkable. Among them, whitening mouthwash can remove stains and pigmentation, and can help brighten teeth, but has no whitening effect; The anti-smoke stain mouthwash is for men, and it adds eucalyptus oil, menthol, tea leaf extract and other ingredients to cleanse and remove odors. Another Hello Kitty mouthwash is suitable for children and people who are more sensitive to oral astringency, which not only has a mild taste, but also has a less obvious sour feeling.
 
In terms of packaging design, Bina's has done a better job, and the solid color bottle body is very simple and generous. At present, Bina's has entered China, and most of the products can be bought in Tmall supermarket, and the prices of different products vary, roughly between 50-70 yuan.
