Abstract
The invention relates to whitening strips. The whitening strips comprise water-insoluble film layers, whitening layers and adhering-resistant lining layers, wherein the whitening layers include whitening agents, gels and water; and the gel is one or more of veegum, natural gum and polyvinylpyrrolidone. The whitening strips are conveniently adhered on the surfaces of the anterior teeth and a trough between every two teeth, can quickly release the whitening agents and protect the soft tissues such as gum and lips, and are conveniently taken out after use without hurt to the soft tissues in the mouth. The white strips are convenient, safe, efficient, and quick in acting during use. In the prior art, hydrogen peroxide which is beneficial for whitening the teeth bring extreme discomfort to the soft tissues in the mouth due to the concentration, and if the concentration of the hydrogen peroxide is reduced, the using time needs to be prolonged, and the problem is effectively solved by the whitening strips by adding the gels.
Description
Technical field
The invention belongs to filed of daily-use chemical industry, relate generally to a kind of efficient, safe, practical U.S. tooth-whitening paster.
Technical background
At present the most frequently used oral cleaning tool is toothbrush still, but utilizes the mechanical movement of toothbrush only can remove intraoral food debris and part tartar, for the prevention of the problems such as tartar, dental plaque, oral inflammation, gingival hemorrhage and treat like water off a duck's back.Therefore first toothpaste that contains surfactant and abrasivus arises at the historic moment nineteen fifty-five.After toothpaste occurred, people began to notice the teeth brushing way of physical motion, are equipped with the effect that suitable chemical constituent can reach better nursing oral cavity, so have antiinflammatory, protect gum, the toothpaste of the effect such as anti-hemodia goes on the market in succession.
Follow health closely thereafter, what people paid close attention to most is exactly the beautiful teeth problem.No matter in social life or private contact, pure white tooth and beautiful smile can both give own self-confident, give again others comfortable sensation and favorable impression.The chemical constituent that is used at present teeth whitening mainly contains peroxide, such as hydrogen peroxide, urea peroxide, Dexol, SODIUM PERCARBONATE; Chlorite and hypochlorite are received etc. such as calcium chlorite, that barium chlorate, magnesium chlorite, aluminium chlorite, sodium chlorite, potassium chlorite, hypochlorous acid.In addition, zinc citrate, phytic acid are received, noble and unsullied property silicon dioxide also is whitening composition common in the whitening toothpaste.Wherein use the history in existing 40 years of hydrogen peroxide tooth-whitening, its effect ﹠ Safety is high than other tooth whitening compositions, is still at present the effective ingredient of commonly used in Household tooth whitening product and the professional tooth whitening mode or auxiliary usefulness.Yet hydrogen peroxide itself is unstable, easily resolves into water and oxygen, therefore generally its form with hydrogen peroxide soluble in water is preserved.Hydrogen peroxide is directly used in tooth whitening, then can infiltrate because it is mobile the oral soft tissues such as gingiva, tongue, lip.The extreme that can cause soft tissue to the effective hydrogen peroxide concentration of tooth whitening is uncomfortable, then needs to prolong its service time if reduce the concentration of hydrogen peroxide.It is reported that do not affect soft tissue if hydrogen peroxide concentration is low to moderate, then the hydrogen peroxide of this concentration need use 2-5 talent can reach the effect of tooth whitening.
In view of the foregoing, the application mode of hydrogen peroxide in tooth whitening products just become people's problems of concern.Wherein mode is to use dental tray the most intuitively, and this mode can effectively be isolated hydrogen peroxide and oral soft tissue and tooth moment is contacted with hydrogen peroxide.Make certain density hydrogen peroxide dilution but this application mode can stimulate user to produce a large amount of saliva, and be dissolved in and swallow saliva and hydrogen peroxide.
Summary of the invention
For addressing the above problem, the present invention adds suitably an amount of thickening agent to increase the viscosity of hydrogen peroxide, reduces its flowability.
The invention provides a kind of U.S. tooth-whitening paster, comprise water non-soluble film layer, release liner nexine and be positioned between the two whitening layer, described whitening layer by weight, comprises:
Whitening effect composition 2.5-20%;
Gel 20-30%;
Water 10-80%.
Described gel is one or more in Wei Gemu, natural gum, the polyvinylpyrrolidone.
Preferred gel is polyvinylpyrrolidone, and content is 25%.
The long 2cm-12cm of described water non-soluble film layer, wide 1cm-2cm, thick 0.005mm-0.1mm bending rigidity is at 0.1grams/cm-3grams/cm, and whole U.S. tooth-whitening paster gross thickness is at 0.2mm-0.6mm.
The material of described water non-soluble film layer is Molecularly Imprinted Polymer, natural fabric, synthetic fabric, paper tinsel film or synthetic rubber.
The material of described water non-soluble film layer is polyethylene, poly-ethyl vinyl alcohol, ethylene vinyl acetate copolymer.
Described U.S. tooth-whitening paster by weight, also comprises PH regulator 0.1-0.2%, mouth care composition 1-10%.
Described mouth care composition comprises except in the tartar tartar composition, preventing decayed tooth composition, antimicrobial component, anti-inflammatory component, nutrient composition, enzyme, bisfentidine one or more.
Describedly comprise in pyrophosphate, Quadrafos, the poly phosphate one or more except tartar tartar composition; Described preventing decayed tooth composition comprises fluorion, such as in sodium fluoride, potassium fluoride, the aluminium fluoride one or more; Described antimicrobial component comprises one or more in phthalic acid and salt thereof, chlorhexidine, alexidine, Sanguinarine, benzalkonium chloride, domiphen bromide, paraphthaloyl chloride, octenidine, delmopinol, octapinol, Augmentin, the amoxicillin; Described anti-inflammatory component comprises one or more in ketorolac, ketoprofen, BTS-18322, ibuprofen, naproxen, indomethacin, aspirin, piroxicam, the meclofenamic acid; Described nutrient composition comprises one or more in metal ion, vitamin, the aminoacid; Described enzyme component comprises one or more in protease, glucan hydrolase, endoglycosidase, amylase, Mutanase, lipase, mucase, the mucopolysaccharidase; Antioxidant composition comprises one or more in vitamin A and C and E, uric acid, carotenoid, flavone, polyphenol, melatonin, amino indole, the thioctic acid.
1. these tooth subsides are conveniently used and are carried, and its whitening effect is high, speed is fast, can satisfy people for the pursuit of tooth whitening, improves confidence, is convenient to social activity, produces good social benefit.
2. can add other oral cavities and dental care composition according to different needs when this tooth is attached to whitening, reach other oral cavities and dental care effect, have good prevention and treatment meaning.
3. along with people living condition's raising, people are more and more higher for requirement and the consciousness of tooth and oral health, and this product will obtain comparatively objectively economic benefit
4. the zest to the oral cavity is little, can not dilute effective whitening composition.
