In the toothpaste market, where old national brands such as China and blacks have been acquired or injected by foreign capital, Naaisi is one of the few "domestic toothpaste brands that can survive". Today, the brand belongs to Naaisi Group, headquartered in Zhejiang Province, and has five overseas production bases in Hunan, Sichuan, Hebei and other cities, and has a relatively strong market scale among China's daily chemical brands.
 
The main concept of "nutritional toothpaste" is Naais toothpaste, and the representative products are stain removal vitamin C toothpaste and nutritional vitamin E toothpaste. Although in terms of the actual addition of ingredients, the content of vitamin C and vitamin E ingredients advertised is negligible, and because toothpaste is an oral temporary product, the short stay time of these ingredients basically does not achieve any nutritional effect. However, as far as the overall toothpaste system is concerned, these two toothpastes are made of hydrated silica mild abrasives, adding sodium fluoride anti-moth ingredients, which are qualified basic cleaning toothpastes, plus a high cost performance of about 10 yuan, which is also worth recommending.
 
In addition to nutritious toothpaste, the Jianshuangbai series is the latest flagship product of Naaisi, with whitening, fresh and anti-allergenic three models, all of which are fluoride toothpaste, and the price is between 20-30 yuan. This series of toothpastes uses soft silica abrasives, which are moderately soft and hard, and have relatively mild and effective cleaning power. Of course, the addition of functional ingredients is relatively perfunctory, for example, the whitening version still uses colorants to achieve instant whitening effect, and it is recommended that people who purchase Naais toothpaste do not have expectations for its claimed efficacy.
