Abstract
The invention provides toothpaste containing fumed silica and sodium tripolyphosphate. The toothpaste consists of the following raw materials in percentage by weight: 3 to 17 percent of the sodium tripolyphosphate, 0.1 to 3 percent of the fumed silica, 6 to 15 percent of abradant, 20 to 55 percent of humectant, 0.5 to 2.5 percent of binder, 1.0 to 3.0 percent of foaming agent, 0.1 to 0.3 percent of sweetener, 0.1 to 0.5 percent of preservative, 0.6 to 1.5 percent of essence, and the balance of deionized water. The toothpaste has the advantages that the sodium tripolyphosphate has the function of whitening, the fumed silica can reduce the dosage of precipitated silica in the formula, and the toothpaste cannot be drawn and has good thixotropy and nice strip forming appearance.
Description
Technical field
The present invention relates to a kind of toothpaste, relate in particular to a kind of toothpaste that contains fumed silica and sodium tripolyphosphate.
Background technology
The toothpaste variety that on the market with silicon dioxide is now abrasive is various, but toothpaste is the precipitated silica Technology with the production technology of abrasive-silicon dioxide on the market, does not see patent report with the technology of fumed silica production toothpaste.
Vapor phase method and precipitated silica are multi-purpose industrial chemicals, and they are isomerss of native silicon dioxide, and their molecular formula are identical, but the molecular structure difference.
Precipitated silica technology is that waterglass (or claiming bubble flower alkali) carries out chemical reaction with acid (sulphuric acid, hydrochloric acid, mineral acid, organic acid etc.).
Precipitated silica has rubber grade precipitated silica and toothpaste level precipitated silica, the Technology difference, and the former is the formation technology of colloidal sol, and the latter is the formation technology of gel, and the characteristic of gel embodies in the lotion of toothpaste that is shaped.Toothpaste level precipitated silica, silicon dioxide specific area 849m2/g, average primary particle diameter 60-80nm, oil factor (ml/100g) is below 290.
Fumed silica burns in oxyhydrogen flame by chloride and carries out the high temperature vapor phase hydrolysis, produces through subtractive processes such as cohesion, separation, deacidification, screenings.
SiCL4+2H2+O2---SiO2+4HCL
Fumed silica, silicon dioxide specific area 200 ± 25m2/g, average primary particle diameter 12nm, bulk density 50g/l, apparent density 30g/l, the application mechanism of pH value (4% aqueous dispersion) 3.7-4.1 fumed silica: in liquid system, have great amount of hydroxy group owing to the fumed silica surface, these hydroxyls can form hydrogen bond between the aggregation of fumed silica, when it is well-dispersed in the liquid system, just form the network structure of silicon dioxide, it is arranged as shown in Figure 1.This network can increase the viscosity of liquid, and produces the thixotroping phenomenon.
Trimerization phosphorus sodium, white crystals or crystalline powder.622 ℃ of fusing points, (about 13%) soluble in water.Alkali metal and heavy metallic salt there are complexing power, can softening of water.1% aqueous ph value is 9.5.Have ion-exchange performance, make suspension become solution, sodium tripolyphosphate is a kind of inorganic matter surfactant, and lubricated oil ﹠ fat is had intensive emulsification, has the character of certain Organic substance surfactant.The effect of good dispersant is also arranged simultaneously,
Impel material particles to be dispersed in the medium, form the medicament of stable suspension.Dispersant generally is divided into inorganic dispersant and organic dispersing agent two big classes.Inorganic dispersant commonly used has silicates (for example waterglass) and alkali metal phosphate class (for example sodium tripolyphosphate, sodium hexameta phosphate and tetrasodium pyrophosphate etc.).Organic dispersing agent comprises triethyl group hexyl phosphoric acid, sodium lauryl sulphate, methyl anyl alcohol, cellulose derivative, polyacrylamide, guar gum, fatty acid polyethylene glycol ester etc.
Dirt particles suspends in water on the tooth so sodium tripolyphosphate interaction energy in toothpaste makes, easily by rinsing
Summary of the invention
The object of the present invention is to provide a kind of toothpaste that contains fumed silica and sodium tripolyphosphate, this toothpaste contains the composite production toothpaste of sodium tripolyphosphate and fumed silica and precipitated silica, adds the sodium tripolyphosphate and the fumed silica effect with thickening power that tooth are had whitening effect in toothpaste.
The present invention is achieved like this, and it is characterized in that being made up of the raw material of following weight fraction: sodium tripolyphosphate 3～17%, fumed silica 0.1～3%, abrasive 6～15%, wetting agent 20～55%, binding agent 0.5～2.5%, foaming agent 1.0～3.0%, sweeting agent 0.1～0.3%, antiseptic 0.1～0.5%, essence 0.6～1.5%, deionized water surplus.
Described sodium tripolyphosphate is a food grade sodium tripolyphosphate; Described abrasive is friction type, thickening type, mixed type a kind of of the silicon dioxide of sedimentation method explained hereafter or some kinds mixture; Described wetting agent is the mixture of a kind of in glycerol, sorbitol, propylene glycol, the PEG400 or some kinds; Described binding agent is the mixture of a kind of among xanthan gum, sodium carboxymethyl cellulose, guar gum, carbomer, the F-127 or some kinds; Described foaming agent is the mixture of a kind of of sodium lauryl sulphate and sodium lauroyl sarcosine, cocamido propyl betaine or some kinds; Described sweeting agent is a saccharin sodium, and described antiseptic is the mixture of a kind of of sodium benzoate, ethylparaben sodium, soluble propylhydroxybenzoate or some kinds.
Its preparation method is: 1, suck wetting agent in the vacuum Manufacturing medicine extract machine under vacuum state;
2, again sweeting agent, antiseptic water are dissolved in the small powder pot, after stirring, under vacuum state, stir with wetting agent in the suction vacuum Manufacturing medicine extract machine;
3, after binding agent and foaming agent, abrasive, fumed silica, food grade sodium tripolyphosphate were poured into and stirred in the powder pot, thing stirred 15-18 minute in the suction vacuum Manufacturing medicine extract machine neutralization procedure 2 under vacuum state;
4, under vacuum state, suck essence at last and stirred 10-15 minute, go out cream promptly.
Advantage of the present invention is: the effect of sodium tripolyphosphate Pear Power, fumed silica can reduce the use amount of precipitated silica in prescription, not wire drawing of mastic simultaneously, and the mastic thixotropy is good, and the outward appearance stripping is better.
