Description

Liquid Toothpaste Composition {LIQUID TOOTHPASTE COMPOSITION}

The present invention relates to a liquid dentifrice composition, and more particularly to a liquid dentifrice composition with significantly improved retention and dispersion stability of low viscosity liquid dentifrice.

Conventional liquid toothpaste is important to control the balance between low retention and fluidity.

The low prosthesis could not maintain a consistent shape for dispensing from clean, small, flexible plastic bottles. If the shape retention of the liquid toothpaste is too strong, it becomes a toothpaste without fluidity, while if the shape retention is too weak, there is a problem that flows with water. Accordingly, methods for improving the correction and fluidity of liquid toothpaste have been continuously studied.

Korean Patent Application No. 2001-7004081 discloses a liquid tooth cleaning gel in which the ratio of water and humectant is transparent and not too liquid at low temperatures and does not go too quickly or too deeply with the toothbrush when applied to the toothbrush. It discloses a manufacturing method of. However, this method has a problem of low shape retention and fluidity.                         

Therefore, there is a need for research on liquid toothpaste having excellent shape retention and fluidity.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a liquid dentifrice composition that not only has excellent shape retention and fluidity, but also significantly improves dispersion stability.

In order to achieve the above object, the present invention provides a liquid toothpaste composition comprising 0.1 to 5% by weight of casein sodium (sodium caseinate) in the liquid toothpaste composition.

Hereinafter, the present invention will be described in detail.

The present inventors studied liquid toothpaste having excellent shape retention and fluidity, and as a result of adding sodium caseinate, which is conventionally used as a food additive, to liquid toothpaste, a low viscosity (10,000 to 100,000 cps) liquid toothpaste was added. It was confirmed that the formation can be improved and the dispersion stability can be improved, and the present invention was completed based on this.

Casein sodium used in the present invention serves to remove the bubbles of ice cream, used as a protective gelling agent of powdered creams in powdered foods or instant foods containing fats, conservatives, sausage, bread, Or, it is used for various purposes such as maintaining the shape of biscuits, cleaning agent for making sake, and taltanine for making wine. Especially, it is used for high protein food and low sodium in the manufacture of health supplements and medicines.

Liquid toothpaste composition of the present invention serves to improve the shape retention, fluidity, and dispersion safety of the product by forming a fine cell by combining with the abrasive component of the casein sodium toothpaste (sodium caseinate).

The casein sodium is included in the liquid dentifrice composition in an amount of 0.1 to 5% by weight, when the content is less than 0.1% by weight, the effect of improving shape retention, fluidity, and dispersion stability is insignificant. There is a problem of lowering the fluidity, which is the basic physical properties of toothpaste.

The liquid toothpaste composition of the present invention may be used in combination with an appropriate amount of abrasives, wetting agents, agonists, binders, foaming agents, flavorings, sweeteners, coloring agents, and the like commonly used according to the type and purpose of the composition.

The abrasive may be precipitated silica, silica gel, zirconium silicate, calcium monohydrogen phosphate, calcium hydrogen phosphate anhydrous, hydrous alumina, hard calcium carbonate, heavy calcium carbonate, calcium pyrophosphate, insoluble metaphosphate, aluminum silicate, and the like. Is using precipitated silica, silica gel, or zirconium silicate. The abrasive is preferably contained in 1 to 90% by weight in the liquid toothpaste composition.

The humectant is a base ingredient essential for making a liquid formulation, which prevents the toothpaste from drying and solidifying when exposed to the air, provides shine to the surface of the toothpaste, and plays a role in imparting sweetness upon brushing. The wetting agent may be concentrated glycerin (98%), glycerin (85%), sorbitol aqueous solution (70%), amorphous sorbitol aqueous solution (70%), polyethylene glycol, propylene glycol and the like.

The humectant is preferably included in the liquid toothpaste composition in an amount of 20 to 75% by weight. If the amount is less than 20% by weight, the degree of drying and solidification is high when the liquid toothpaste is exposed to the air. There is a problem that there is no gloss.

The pharmacological agent may be a water-soluble fluoride such as sodium fluoride, sodium fluoride phosphate, amine fluoride, or tin fluoride; Sodium pyrophosphate, potassium pyrophosphate, or acidic pyrophosphate; Cationic surfactants; Enzymes; Water-soluble salts such as sodium chloride or sodium bicarbonate, amino acid caproic acid, allantoin, or allantoin derivatives; Or vitamins can be used.

The drug is preferably included in the liquid dentifrice composition in an amount of 0.01 to 2.0% by weight. If the content is less than 0.01% by weight, the effect according to the component is insignificant, when it exceeds 2.0% by weight there is a problem that the effect according to the addition amount is insignificant.

The water-soluble fluoride is substituted with the hydroxyapatite of the tooth enamel to form a fluoride apatite to increase the hardness of the tooth, thereby preventing tooth decay. In addition, the sodium pyrophosphate, potassium pyrophosphate, and acidic pyrophosphate are effective for inhibiting tartar formation, the cationic surfactant is effective for bactericidal bacterium in the oral cavity, and the enzymes are effective for inhibiting and removing plaque. In addition, the water-soluble salts serve to prevent periodontal disease, aminocapronic acid, allantoin, allantoin derivatives, and vitamins are hemostatic action.                     

The binder serves to prevent the powder component and the liquid component from being separated from each other. The binder may be any water-soluble polymer, but in particular, carboxymethylcellulose sodium synthesized from cellulose of trees, carrageenans extracted from seaweeds, xanthan gum obtained from metabolism of microorganisms, and the like may be used.

The binder is preferably contained in 0.1 to 5% by weight in the liquid toothpaste composition, when less than 0.1% by weight there is a problem that the powder component and the liquid component is separated.

The foaming agent enhances the feeling of use of the product and helps cleansing action, and facilitates the dissolution of foreign substances in the oral cavity by speeding up the dispersion and penetration of other active ingredients and reducing the interfacial tension. As the foaming agent, polyoxyethylene which is an anionic surfactant, a copolymer of polyoxypropylene (poloxamer), polyoxyethylene hardened castor oil, polyoxyethylene sorbitan fatty acid ester, or the like can be used.

The foaming agent is preferably contained in the liquid dentifrice composition in 0.5 to 5% by weight, when less than 5% by weight can not obtain the effect of peeling foreign substances in the oral cavity from the teeth, when the content exceeds 5% by weight decreases the feeling There is a problem.

In addition, the fragrance, sweetener, and coloring agent may be used in an appropriate amount to improve the feel of the toothpaste. As the fragrance, the use of edible edible fragrance is essential, and examples thereof include peppermint oil, spearmint oil, sage, eucalyptol, methyl salicylate, and fruit extract. As the sweetener, sodium saccharin is mainly used, and food coloring is mainly used as a coloring agent.                     

In addition, the liquid toothpaste composition of the present invention contains a residual amount of water in addition to the genital components.
