Description

Zeolite toothpaste abrasive and preparation method thereof

Technical Field

The invention relates to the technical field of components and preparation of toothpaste abrasives, in particular to a zeolite toothpaste abrasive and a preparation method thereof.

Background

The components of the toothpaste mainly comprise: abrasives, foaming agents, humectants, thickeners, preservatives, fragrances, sweeteners and water. Wherein, the abrasive is an essential component in the formula of the toothpaste, and generally accounts for 20 to 50 percent. The abrasive agent of the toothpaste is used for removing dirt and colored substances attached to the surfaces of teeth during the use process. Raw materials used as toothpaste abrasives generally require proper hardness and friction value, uniform particle fineness, no peculiar smell, comfortable mouthfeel, safety, no toxicity, small solubility and stable chemical property, and do not react with other components in toothpaste. Currently, the commonly used raw materials of the abrasive include silica, aluminum hydroxide, calcium carbonate, and the like.

Currently, more and more reports and studies indicate that the incidence of wedge-shaped defects in teeth of people with brushing habits is much higher than that of people without brushing. Studies have shown that toothpastes containing too hard abrasives as well as those containing harsh abrasives wear the dentin severely and can even result in dentin exposure and allergic reactions. Therefore, toothpastes made with abrasives such as silica, aluminum hydroxide, calcium carbonate, etc. create a contradiction between the maintenance of oral hygiene and tooth safety for people who have a brushing habit. Therefore, a new technical scheme needs to be researched to solve the problem that the existing technical scheme is repeated and difficult to eradicate; in addition, in order to improve the acne removing effect, chemical raw materials with skin stimulation are often added, and the acne is aggravated after the soap product is used for a long time. For this reason, a corresponding technical scheme needs to be designed for solution.
