Preparation method of solid-liquid separation toothpaste and corresponding container structure

Abstract

The invention discloses a preparation method of toothpaste and a corresponding container structure. The preparation method is used for separately filling solid components and liquid components in the toothpaste into an independent space. According to the method, the humidity of the solid components in the toothpaste is controlled, so that the propagation conditions of microorganisms in the toothpaste are reduced. The phenomena of toothpaste odor change, water separation, flatulence and the like caused by microorganism propagation are reduced, so that the purpose of adding no preservative or adding a small amount of preservative into the toothpaste is achieved, and better health performance is brought to a user. According to the method and the structure, when liquid and solid are mixed before use, the characteristics that different components in solid powder are different in specific gravity, stacking density, water solubility and hydrophilicity are utilized, and the gravity action is combined, so that various components are uniformly mixed into a toothpaste body in a natural standing state, and the purpose of convenient use is achieved.

Description

[0001] Application fields: [0002] The invention is mainly used in the field of manufacture and use of toothpaste. It also includes cosmetics and medicines in the form of other creams. The specific application is in the control of microorganisms in the ingredients and the reduction of the amount of preservatives added. [0003] technical background: [0004] The current production of toothpaste at home and abroad has adopted the method of mixing solid components such as abrasives, foaming agents, fragrances, thickeners, adhesives, and preservatives with liquid components such as water and humectants, and then stirring , the technology of filling into toothpaste tubes. The solid components in toothpaste are all milled to a certain mesh size for easy dispersion. [0005] The advantage is that the toothpaste composition ratio can be quantitatively and qualitatively. After the toothpaste is mixed, it becomes a paste with good extrudability and formability. Users only need to s...

Problems solved by technology

Therefore, the amount of preservative added will inevitably increase.

And whether it is adding traditional Chinese medicine or western medicine ingredients, these ingredients will have a certain loss of efficacy due to the long-term exposure to the acid, alkali, and salt environment in the mixed paste

[0009] 3. If certain preservatives are not added, along with the reproduction of microorganisms in the paste, there will be odor changes, water separation, swelling and other phenomena in the paste, which will affect the quality of the toothpaste and the use of users

[0010] 4. As far as we know, no matter what kind of preservatives are harmful to the human body to varying degrees

After some toothpaste remains between the teeth, it often enters the human body with saliva, causing harm
