The toothpaste prepared by using the method provided by the invention brings highly efficient and mild cleaning effect, excellent whitening effect and good odor removing effect to teeth. The application scope of the toothpaste is wide.

Description

A kind of zirconium toothpaste that contains
Technical field
The invention belongs to filed of daily-use chemical industry, particularly a kind of chemical compound of zirconium in toothpaste as application and a kind of zirconium toothpaste that contains of deodorizer.
Background technology
Usually add medicinal herb componentses such as Flos Chrysanthemi Indici, Flos Lonicerae in the toothpaste and play the deodorant effect; For example; Per 100 parts of toothpaste contain 20～40 parts of ingredients in a kind of halitosis-removing toothpaste, and wherein ingredient is made by following raw materials according: Herba Asari, Rhizoma Cimicifugae, fragrant flower bud, Herba Pelargonii Graveolentis, Radix Et Rhizoma Nardostachyos, the Radix Angelicae Dahuricae, Mirabilitum crystallina, Gypsum Fibrosum, Radix Puerariae, Radix Paeoniae Rubra, Herba Agrimoniae, Folium Stevlae Rebaudianae, Herba Menthae, Sal.The problem that these methods exist is: raw material is formed complicated, or the Chinese herbal medicine extracting process is more loaded down with trivial details.
Abrasivus is the main body that toothpaste is formed, and adopts calcium carbonate, magnesium carbonate, calcium phosphate, calcium sulfate, Polymeric sodium metaphosphate., Alumina, silicon dioxide etc. as toothpaste abrasives usually.Through mechanism, the powdery solid abrasivus with suitable particle size and hardness can be removed dental plaque, can not damage enamel simultaneously.
Adopt the chemical compound of zirconium to make toothpaste abrasives domestic beyond example still at present.Zirconium orthosilicate. (ZrSiO 4) chemical stability, fusing point is up to 2500 ℃, is a kind of high-quality, inexpensive opacifiers, is widely used in the production of various architectural potteries, sanitary ceramics, domestic ceramics, one-level artware pottery etc.Employing Zirconium orthosilicate. (ZrSiO is abroad arranged 4) have cleaning and tooth-whitening effect, for example European patent JP 003081795 (A) (TOOTHPASTE COMPOSITION) and KR 20040021954 (A) (WHITENING TOOTHPASTE COMPOSITION) preferably as toothpaste abrasives.
The other several kinds of chemical compounds of zirconium specifically have following characteristic:
Zirconium carbonate (ZrOCO 3 nH 2O): white crystalline powder, odorless, tasteless, water insoluble and organic solvent is dissolved in acid solution, emits carbon dioxide simultaneously.Be used for the inorganic agent of the high-grade paint of papermaking weaving and cosmetics, production, high grade paint and fiber, also can be used as deodorizer, sorbent, medical mildew-resistant etc.
Zirconium hydroxide (ZrO (OH) 2nH 2O): white unformed powder, nonpoisonous and tasteless, be soluble in mineral acids such as hydrochloric acid.Water insoluble and aqueous slkali can be used for making adsorbent, deodorizer, pigment, dyestuff, glass etc.
Zirconium dioxide (ZrO 2): be the main oxides of zirconium, usual condition for white odorless, tasteless crystal, is insoluble in water, hydrochloric acid and dilute sulfuric acid down.Chemical property torpescence, but the character of high-melting-point, high resistivity, high index of refraction and low thermal coefficient of expansion make it become important exotic material, ceramic insulating material and ceramic opacifier.Also be a kind of very outstanding high-tech biomaterial, good biocompatibility, and, nothing irritated reaction non-stimulated to gingiva are well suited for being applied to the oral cavity ceramic material.
In the prior art still the chemical compound of the above-mentioned three kinds of zirconiums of no-trump be applied to the precedent in the toothpaste.
Summary of the invention
The chemical compound that the technical problem that the present invention solved is to provide a kind of zirconium in toothpaste as application and a kind of zirconium toothpaste that contains of deodorizer.
The technical solution that realizes the object of the invention is: a kind of chemical compound of zirconium in toothpaste as the application of deodorizer.
A kind of zirconium toothpaste that contains comprises abrasivus, wetting agent, binding agent, detergent, sweeting agent, essence, antiseptic, pure water and deodorizer, and said deodorizer is ZrO 2(zirconium dioxide), ZrOCO 3 nH 2O (zirconium carbonate), ZrO (OH) 2nH 2The mixing of one or more among the O (zirconium hydroxide).
A kind of zirconium toothpaste that contains comprises abrasivus, wetting agent, binding agent, detergent, sweeting agent, essence, antiseptic, pure water, and said abrasivus is ZrO 2(zirconium dioxide), ZrOCO 3 nH 2O (zirconium carbonate), ZrO (OH) 2nH 2The mixing of one or more among the O (zirconium hydroxide).
The present invention compared with prior art, its remarkable advantage is: 1) ZrO 2(zirconium dioxide), ZrOCO 3 nH 2O (zirconium carbonate) and ZrO (OH) 2nH 2Nontoxic, tasteless, the nonirritant of O (zirconium hydroxide), safe in utilization; 2) chemical compound of above-mentioned three kinds of zirconiums also has the deodorant effect concurrently except that cleaning the teeth through physical friction; 3) chemical compound of above-mentioned three kinds of zirconiums can brute force remove stain, cleaning and whitening teeth, is going aspect tobacco dirty remover, tea stain, coffee stain and the whitening teeth special effect is arranged; 4) cleaning teeth that toothpaste of the present invention can efficient gentle safety, non-stimulated to gingiva and tooth, do not have that allergy is reacted, had no side effect, health, mouthfeel be good.
