High-salt composition with anti-dentin sensitivity and whitening functions, toothpaste and preparation method thereof

Abstract

The invention discloses a high-salinity composition having functions of resisting dentine hypersensitivity and whitening. The composition comprises the following components in parts by weight: 4-8 parts of potassium nitrate, 0.1-5 parts of pyrophosphate and 3-5 parts of auxiliary sensitivity resisting ingredient; the invention further discloses application of the high-salinity composition in a toothpaste, a tooth powder, a tooth gel, a tooth paste or a cream preparation; the invention further discloses a toothpaste comprising the high-salinity composition, and the weight percentage of the high-salinity composition in the whole toothpaste is 7-18%; the invention further discloses a preparation method of the toothpaste: a humectant is added in a container, then a thickener is added to stir evenly, a sweetening agent, a preservative and a surfactant are added to be stirred evenly, the high-salinity composition is added and stirred evenly, an abrasive and water are added, a fragrance modifier is added after stirring evenly, and the mixture is fully stirred and degassed in vacuum to complete the preparation of the toothpaste. The high-salinity composition and the toothpaste have excellent double effects of whitening and resisting hypersensitivity, the components work synergistically, and the effect is more remarkable.

Description

technical field [0001] The invention relates to an anti-sensitivity and whitening oral product, in particular to a high-salt composition with anti-sensitivity and whitening functions, toothpaste and a preparation method thereof. Background technique [0002] Dentin sensitivity, also known as dentin hypersensitivity, is commonly known as "inverted teeth". Due to factors such as incorrect tooth brushing methods, poor eating habits, or aging, symptoms such as acid erosion, enamel wear, wedge-shaped defects, and gingival recession are caused, and eventually the dentin is exposed. When the teeth encounter external stimuli such as cold, hot, sour, sweet, etc. or brushing, a short and sharp pain is caused, which is dentin sensitivity. The main manifestations are dental soreness, "hair soaking", rapid onset, sharp pain, and short duration. [0003] Extrinsic staining of teeth refers to the deposition of foreign pigments that enter the oral cavity or pigments produced by bacteria i...

AI Technical Summary

Problems solved by technology

[0010] But above-mentioned toothpaste also has the following problems: 1. In specific implementation, there is no implementation of addition higher than 3% potassium nitrate toothpaste, because the toothpaste paste body of high salt content is extremely unstable, is difficult to implement

2. There is no pyrophosphate in the toothpaste, and it cannot completely chelate tooth stains and remove dental plaque under the premise of reducing tooth wear, and the anti-dentin sensitivity ingredients cannot fully act on dentin tubules. The effect is not ideal

3. For people with dentin sensitivity, teeth whitening will cause short-term dentin sensitivity, and the lack of necessary anti-dentin sensitivity ingredients will affect the health of patients receiving tooth whitening treatment

However, due to the complex formula components, the paste is extremely unstable, and the taste is not easy to control. There are few oral products with anti-dentin sensitivity and whitening functions on the market, and the existing products have synergistic effects in the treatment of dentin sensitivity and whitening. not ideal
