Embodiment 1
[0118] Embodiment 1: The product is a paste, prepared with the following raw materials: didecyldimethyloxyproline ammonium, propylene glycol, polyvinylpyrrolidone, carbamide peroxide, fumed silica, menthol, water-soluble pigment, water-soluble Peppermint Flavor Powder (Firmenich, APL0504), Sucralose, Sodium Saccharin, Disodium EDTA, Poloxamer.
[0119] The preparation method is as follows:
[0120] A. Uniformly disperse polyvinylpyrrolidone in propylene glycol, and then stand to swell fully to obtain colloid A;
[0121] B. Heating the propylene glycol, and fully dissolving the poloxamer in the propylene glycol to obtain solution B;
[0122] C. Add cationic antibacterial agent, sweetener, water-soluble pigment, antioxidant, chelating agent, water-soluble essence and other components into solution B respectively, and fully stir to obtain solution C;
[0123] D. Divide the required fumed silica into three parts, two of which are added to solution C in two times, and after fully...

Abstract
The invention discloses an anhydrous matrix for oral products and application of the matrix, and belongs to the technical field of the oral products. The anhydrous matrix is characterized in that theoral products can stably exist when one of or both of a peroxide source and a cationic antibacterial agent are added into the matrix; the matrix is composed of propylene glycol, fumed silica and polyvinylpyrrolidone, and the weight ratio of the three components is 1:(0.03-015):(0.01-0.08). The cationic antibacterial agent can be a quaternary ammonium salt or a guanidine antibacterial agent, and can be didecyl dimethyl ammonium praline sodium (PODA) or cetylpyridinium chloride. The peroxide source can be a complex of urea peroxide or calcium peroxide, or percarbonate or perborate, or hydrogen peroxide, or polyvinylpyrrolidone hydrogen peroxide. The anhydrous matrix is used for preparing products for removing oral biofilm. The matrix achieves the effect that in the same system, the peroxidesource and the cationic antibacterial agent can stably coexist and synergistically inhibit and damage the biofilm.
Description
technical field [0001] The invention belongs to the technical field of oral products, and in particular relates to a water-free matrix which can stabilize one or both of a peroxide source and a cationic antibacterial agent, and an oral product made on the basis of it is effective in removing oral organisms. applications in the membrane field. Background technique [0002] The peroxide source refers to the compound containing peroxy group -O-O-, which is characterized by the presence of peroxide ion in the molecule. After the peroxide is dissolved in water, the oxygen element of the peroxy group -O-O- is in a high-valent state, and it can undergo redox by itself, one oxygen becomes -2 valence, and one oxygen becomes 0 valence, which is the oxygen atom, also known as new Ecological oxygen, the oxygen atom is unstable, can take away the electrons of the bacteria and become a stable -2-valent oxygen ion to achieve the effect of sterilization. Peroxides are widely used in the f...
