Description

Toothpaste capable of removing smoke smell and smoke stain and preparation method thereof

Technical Field

The invention relates to a toothpaste for removing smoke smell and smoke stain and a preparation method thereof, in particular to a diatomite adsorptive smoke smell absorption and diatomite frictional smoke stain removal toothpaste and a preparation method thereof, belonging to the technical field of oral health products.

Background

The toothpaste is one of common oral products, and mainly comprises three parts, namely, the toothpaste can eliminate halitosis and peculiar smell, inhibit bacteria and diminish inflammation, so that the breath is fresh and the oral cavity is fresh and cool; the second is tooth-care and mothproof, and protects teeth. And thirdly, the abrasive material rubs and cleans to remove tooth stains.

The diatomite is made of amorphous SiO₂Composition and containing a small amount of Fe₂O₃、CaO、MgO、Al₂O₃And organic impurities. Diatomite is generally light yellow or light gray, soft, porous and light, and is commonly used as a raw material of heat insulation materials, filter materials, fillers, grinding materials, water glass and the like in industry.

The diatomite toothpaste is a kind of toothpaste containing diatomite and having the functions of diminishing inflammation, removing smoke smell, removing smoke stain, etc. The effective components in the diatomite toothpaste can absorb smoke smell through the oral cavity during tooth brushing, and the toothpaste organically combines tooth cleaning and tooth disease prevention and treatment, thereby playing a better role in removing taste, preventing oral inflammation, strengthening teeth and removing tooth smoke stain.

For smokers, the throat often feels dry, profuse sputum, and is accompanied by taste and oral discomfort. The prior art discloses a plurality of natural plant toothpastes, but the prior art mostly starts with the drug reaction and taste covering and halitosis removing, the smoke smell in the mouth of a smoker can not be taken away by the adsorption of tooth brushing, and part of the natural plant toothpastes also have heavy drug taste and color, thus the mouth feel and the appearance of the toothpastes are influenced.

The toothpaste is formed by improving on the basis of the dentifrice, and the early dentifrice mainly uses calcium carbonate as an abrasive and soap as a surfactant. Calcium carbonate has a mohs hardness of 3-3.5 and poor abrasion resistance. Since the fortieth years, the toothpaste industry has been greatly improved due to the rapid development of science and technology, and on one hand, the toothpaste industry is the development and application of new abrasives, humectants, thickeners and surfactants, so that the quality of toothpaste products is continuously upgraded and updated; on the other hand, the toothpaste is also developed from the common tooth cleaning function into an oral hygiene product for preventing and treating dental diseases by adding medicines, most prominently, the fluoridated toothpaste greatly reduces the incidence rate of dental caries.

The diatomite is added into the toothpaste in China, but the diatomite of which the algae type is used and how the diatomite is purified and modified can meet the requirement of being applied to the toothpaste, so that the toothpaste containing the diatomite has functions and algae type selections which are not possessed by common toothpaste, the particle size is selected, the particle size interval distribution is large, and the toothpaste special for removing smoke smell and smoke stains does not exist.

Preferably, the toothpaste capable of removing smoke smell and smoke stain is characterized by being prepared from the following raw materials in percentage by weight: 10% of diatom disco earth abrasive, 6-15% of cellulose, 10-25% of sorbitol, 5-2% of hydrated silicon, 0.1-0.5% of sodium phytate, 1.0-3.0% of sodium lauryl sulfate, 0.7-8% of polyethylene glycol-320.2-0.8% of essence, 0.6-0.9% of Chondrus crispus, 0.01-0.1% of saccharin sodium, 0.1-0.3% of methyl hydroxybenzoate and the balance of water. Wherein the whiteness of the diatom earth of the discodermis is 82 percent, the content of amorphous silica is 92 percent, and the bulk density is 0.35 g/mL.

A preparation method of toothpaste for removing smoke smell and smoke spots is characterized by comprising the following steps:

(1) scrubbing the diatom earth of the disc algae for 40 minutes, wherein the mass fraction of the scrubbing is 30%, the dosage of a scrubbing dispersant (such as oxalate or phosphate) is 0.5%, the scrubbing pH value is 6, the centrifugation time is 5 minutes, and the centrifugation speed is 2000 r/min; the sulfuric acid leaching temperature is 98 ℃, the sulfuric acid leaching time is 4h, the sulfuric acid concentration is 5ml/L, the liquid-solid ratio is 2.5:1, the disc algae diatomite after the scrubbing centrifugation and acid leaching treatment process is neutralized to remove the sulfuric acid residue, the disc algae diatomite reaches more than 86% through purification, and the content of amorphous silicon dioxide reaches more than 98%. The bulk density is 0.2 g/mL-0.45 g/mL.

(2) Roasting the disc algae diatomite obtained by the treatment at the temperature of 280-450 ℃, and classifying and selecting the disc algae diatomite with the particle size distribution of 5 microns by air flow, wherein the particle size is 10-40 microns, the Mohs hardness of the disc algae diatomite is 1-1.5, and the skeleton hardness of the disc algae diatomite is 4.5-5. The diatomite is composed of amorphous SiO2 and pectin, and the real hardness of the diatomite is between 2 and 3.

Diatomaceous earth of disc algae: the toothpaste is composed of powder abrasive, humectant, surfactant, binder, perfume, sweetener and other special components. The diatomite is used as an abrasive in toothpaste, is an abrasive and has the functions of adsorption and deodorization. And only the diatomite material in the friction material has the functions of abrasion resistance and adsorption. The toothpaste material is required to be wear-resistant, and the hardness cannot be too hard, and the main factors are hardness and toughness, but the hardness and the toughness are not enough. When the material is hard and not tough, the material is easy to peel off, and the material is hard again and cannot show wear resistance. The toughness and the hardness are not good, so the material can not resist the 'plough' of hard materials and is not wear-resistant. Both of which are the most important. The hardness and toughness are "inversely proportional" and are selected appropriately according to the hardness of the material. Diatomaceous earth is the best candidate! The key to the proper choice of toothpaste is the abrasive.

Diatomaceous earth is a siliceous rock, a fossil of the algal bioskeleton. Mainly distributed in China, America, Denmark, France, Sulian, Romania and other countries. China has 3.2 hundred million tons of diatomite reserves, more than 20 hundred million tons of prospect reserves, high-quality disc algae diatomite is only concentrated in Jilin Changbai diatomite ore areas, resources are excellent and rich, most of other ore deposits are 3-4 grade soil, and the high-quality disc algae diatomite cannot be directly deeply processed and utilized due to high impurity content. The diatomite as toothpaste abradant has the advantages that due to the special shape and structure, the contact area of diatomite particles of the diatomite is larger than that of any abradant material, and the effect of cleaning tooth surfaces by rubbing is better than that of other abradants with irregular particles.

The invention has the advantages that:

1. the high-quality diatomite of the Changbai mountain is selected as the toothpaste friction agent, and the special shape and structure of the diatomite ensure that the contact area of diatomite particles of the disc is larger than that of any friction agent material, and the effect of cleaning the tooth surface by friction is better than that of other friction agents with irregular particles.

2. The high-quality disc diatomite is soft and does not damage teeth, the wear resistance is high, the friction detergency is strong, the area of the disc diatomite contacting the teeth is large, and the smoke stain removing effect on the teeth is better than that of other friction agents. The purified, modified and modified diatomite of the disc algae has large comparative area and strong adsorbability, the smoke smell of the cigarette left in the mouth is neutral organic and inorganic molecules, and the van der Waals force among the molecules is absorbed in the pores of the diatomite structure by the diatomite of the disc algae; meanwhile, harmful substances in the smoke such as ammonia gas and carbon monoxide are polar molecules, and are easy to form intermolecular hydrogen bond combination or chelation with silicon hydroxyl OH groups of diatomite and ion electric adsorption, so that the smoke smell and the smoke stain are favorably purified. 3. The high-quality disc algae diatomite is soft and does not damage teeth, the wear resistance is high, the friction detergency is strong, the area of the disc algae diatomite contacting the teeth is large, and the smoke stain removing effect on the teeth is superior to that of other friction agents.
