Abstract

The invention discloses whitening toothpaste and a preparation method thereof, relates to the field of daily chemicals, and particularly relates to application of beta-cyclodextrin polymer-vitamin C inclusion compound in preparation of functional toothpaste. The toothpaste is characterized by being prepared by the following steps: adding the following components according to the weight of toothpaste in toothpaste production: 40-60 percent of sorbitol, 20-40 percent of silicon dioxide, 5-15 percent of deionized water, 1.5-4 percent of sodium lauryl sulfate, 0.8-1.5 percent of sodium carboxymethylcellulose, 0.1-2 percent of beta-cyclodextrin polymer-vitamin C inclusion compound, 0.2-0.4 percent of titanium dioxide, 0.1-0.2 percent of saccharin sodium and 0.1-0.3 percent of benzyl alcohol; stirring at high speed, and homogenizing to obtain whitening toothpaste. The toothpaste has an effect of protecting oral cavity, teeth and gum at the same time, and has an excellent effect in the aspect of improving the immunity of oral cavity.

Description

A kind of whitening toothpaste

Technical field

The present invention relates to oral cleaning nursing article technical field, be specifically related to a kind of containing β- Toothpaste of cyclodextrin-vitamin C clathrate and preparation method thereof.

Background technology

Toothpaste is indispensable oral cavity cleaning hygienic article, its basic training in people's daily life Can be to clean tooth, fresh breath, reach to keep the purpose of oral cavity cleaning.In recent years, by In consumer, the requirement of self-image is constantly strengthened, toothpaste is proposed more requirement, removes Clean one's teeth and also add functions of some auxiliary tooth-whitening effects.

Existing toothpaste also has the auxiliary whitening composition using interpolation abrasive material, enzyme as toothpaste.This In a little whitening toothpastes, some toothpaste needs the size of abrasive grain to prevent the tooth that weares and teares, and adds Work complex manufacturing；Some toothpaste producing process is simple, but whitening effect is inconspicuous.

Vitamin C also known as L-AA, is people's whitenings of being used in skin-lightening cosmetic the earliest One of agent, is also to be considered safety non-toxic by dermatologist the earliest, can be as the mouth of mottle desalination Take type medicine.But vitamin C is very easy to be affected by external environment, such as transition metal Ion Cu²⁺、Fe³⁺, illumination, pH (particularly alkalescence condition), temperature, high-concentration oxygen Deng.These environmental factorss can make vitamin C go bad so that it is loses original effect.

Cyclodextrin is with the cyclodextrin of cyclodextrin or chemical modification as basic structural unit Macromolecular compound.This polymer had both maintained cyclodextrin inclusion compound, slow release, and had been catalyzed and knows Other ability, again with mechanical strength, stability and the chemistry adjustability etc. that high polymer is good. And the cross-linking type beta cyclo dextrin polymer that mean molecule quantity is 5000～20000 has height Water solublity.

Use above-mentioned beta cyclo dextrin polymer to be coated with vitamin C, vitamin C can not changed Structure in the case of, make vitamin C be in the environment of a relative closure, it is to avoid with the external world Environment contacts, and can also have slow releasing function concurrently simultaneously.So can extend vitamin C at human body Action time, improve its utilization rate, and then reach to extend the effect of drug effect.

Summary of the invention

It is an object of the invention to provide one and effectively oral cavity, tooth and gingiva can be played guarantor Protect effect, the most also have effect toothpaste of tooth-whitening concurrently.

In order to reach the purpose of foregoing invention, the technical solution used in the present invention is: provide one Toothpaste, it is characterised in that: containing beta cyclo dextrin polymer-vitamin in the mastic of described toothpaste C clathrate.

Raw material is prepared with percentage by weight: sorbitol 40-60%, silicon dioxide 20-40%, go Ionized water 5-15%, sodium lauryl sulfate 1.5-4%, sodium carboxymethyl cellulose 0.8-1.5%, Beta cyclo dextrin polymer-vitamin C clathrate 0.1-2%, titanium dioxide 0.2-0.4%, saccharin sodium 0.1-0.2%, benzyl alcohol 0.1-0.3%.

Preparation method:

A, by deionized water, beta cyclo dextrin polymer-vitamin C clathrate, sorbitol and sugar Essence sodium is placed in stirring and evenly mixing in toothpaste machine and, to whole dispersing and dissolvings, obtains mixture；

B, by sodium lauryl sulfate, silicon dioxide, sodium carboxymethyl cellulose, titanium dioxide and Benzyl alcohol addition said mixture stirs, evacuation, continue stirring homogenizing 30 minutes, Turn off homogenizing, continue stirring evacuation degassing, obtain health-care toothpaste.

The toothpaste that the present invention provides is by adding beta cyclo dextrin polymer-vitamin C bag wherein Compound, as the effective ingredient of an auxiliary therapeutic action, makes this toothpaste not only have tooth-whitening and makees With, the most also there is the effect improving oral immunisation power.

Detailed description of the invention

Below in conjunction with embodiment the present invention done further detailed description, but the enforcement of the present invention Mode is not limited to this:

Embodiment:

A, by deionized water 15%, beta cyclo dextrin polymer-vitamin C clathrate 1%, sorbitol 60% and saccharin sodium 0.1% be placed in toothpaste machine and be evenly stirred until whole dispersing and dissolving, obtain mixing Thing；

B, by sodium lauryl sulfate 2.5%, silicon dioxide 20%, sodium carboxymethyl cellulose 1%, Titanium dioxide 0.2% and benzyl alcohol 0.2% add in said mixture and stir, and evacuation continues Continuous stirring homogenizing 30 minutes, turns off homogenizing, continues stirring evacuation degassing, obtains bee pollen and protect Toothpaste.

Take appropriate toothpaste during use to brush teeth, can use at any time when needing.
