Description

Pumping type toothpaste composition improved in elongation property and hardening property}

The present invention relates to a toothpaste composition to be provided by being supported in a pump-type container.

More particularly, the present invention relates to a pump toothpaste composition having improved stretch properties and firmness.

Toothpaste compositions commonly used for cleaning the oral cavity and teeth are products in paste, powder, gel/mucus or liquid form, and there are certain advantages and disadvantages in their use and handling.

The paste-type toothpaste first developed by Colgate in the United States was sold in an aluminum tube, and this aluminum tube was used until the 1970s. The development of aluminum as a laminated film material for such a paste-like toothpaste container as in modern times can be said to have been made with the development of polymer and polymer processing technology. However, this tube-type toothpaste has a high viscosity and is highly likely to cause damage to the tooth enamel layer due to the abrasive component. The reality is that there are many inconveniences such as problems that cause environmental pollution.

Pump toothpaste contained in a plastic container has been released in order to solve the shortcomings of such tube-type toothpaste, but one of the problems of pump toothpaste is that it has a stretching property (tailing), which causes the container to become dirty or the toothpaste retains poor shape on the toothbrush. There is this.

In addition, the existing tube-type toothpaste usually contains sorbitol as a lubricant and moisturizer. Sorbitol is used in an aqueous state of about 70%, but it has a property of rapidly converting to a solid as the water dries, especially as an abrasive. Because it contains this, it can be easily solidified upon contact with air. In particular, the pump toothpaste is required to improve the hardness of the pump toothpaste composition itself because contact with air is inevitable by applying a pump-type container to the toothpaste.

Numerous references are referenced throughout this specification and citations thereof are indicated. The disclosures of the cited documents are incorporated herein by reference in their entirety to more clearly describe the content of the present invention and the level of the art to which the present invention pertains.

In addition, as a pump-type toothpaste composition, it is to provide a toothpaste composition with improved stretching properties and firmness.

Other objects and advantages of the present invention will become more apparent from the following detailed description of the invention, claims and drawings.

One aspect of the present invention is to provide a pump-type toothpaste composition supported in a pump-type container, and a pump-type toothpaste composition comprising an acrylic polymer and a hydrocolloid.

The present inventors have tried to solve the problems of the pump-type toothpaste, tailing (Tailing) and hardening problems due to contact with air. As a result, when the acrylic polymer and the hydrocolloid component are included at the same time, the stretching properties and rigidity are improved, as well as the physical properties that can be discharged through the pump by carrying it in a pump-type container, thereby completing the present invention. became

It may be a polyacrylic polymer, polymethacrylic polymer, polyalkylacrylic polymer, or polyalkylmethacrylic polymer included in the pump-type toothpaste composition of the present invention.

The acrylic polymer is a type of vinyl polymer and may be prepared from an acrylic monomer. As the acrylic monomer, an ester containing a vinyl group, that is, two carbons is a double bond, and one of these carbons (alpha carbon) is Those to which a bornyl group is directly bonded may be used.

An abrasive is a substance that removes plaque (plaque) from the oral cavity, and is essential to increase the removal efficiency of dental plaque and remove hard foreign substances, and has a Mohs hardness of 3 to 6 degrees. In the present invention, the piston of the pump container is made of low-density polyethylene, and since the hardness of the polyethylene is lower than the hardness of the abrasive used, the pump may be worn, so it is preferable to include a small amount of the abrasive. For example, 30% by weight or less, preferably 0.5 to 20% by weight relative to the total weight of the composition may be included. The abrasive may include, for example, any one selected from the group consisting of calcium monohydrogen phosphate, precipitated silica, fumed silica, colloidal silica, zeolite, calcium carbonate, hydrous alumina, kaolin, cellulose, and mixtures thereof, but is limited thereto. doesn't happen

Preferably, the toothpaste composition according to the present invention is provided as a pump-type toothpaste composition, and a small amount of an abrasive is preferably included to prevent pump wear, and a lubricant (polyol, glycerin, etc.) to prevent clogging of the outlet due to drying. It is preferable to include

Lubricant means a substance that reduces friction between two surfaces that slide in contact with each other. It serves to prevent wear. The lubricant may include, for example, any one selected from the group consisting of polyethylene glycol, glycerol, propylene glycol, ethylene glycol, polypropylene glycol, and mixtures thereof, but is not limited thereto. Preferably, it may include any one selected from the group consisting of polyethylene glycol 200 to 600, glycerol, propylene glycol, ethylene glycol, polypropylene glycol, and mixtures thereof. Preferably, as the liquid lubricant, petroleum oil, animal or vegetable oil, synthetic lubricant, etc. may be used, and most preferably, liquid polyol may be used in terms of stability and excellent feeling of use of the composition. Alternatively, the lubricant is not limited to liquid polyol, and may exist in a solid phase at room temperature due to intramolecular interaction of the polymer above a certain molecular weight, such as polyethylene glycol and polypropylene glycol having a polymer form, but through control of the manufacturing temperature It also includes high molecular weight polyols that can be liquefied and can be commercialized and maintained in a stable state.

A flavoring agent and a sweetening agent may be added to the composition of the present invention to suit consumer preferences. The flavoring agent remains in the oral cavity and continuously emits a fragrance to maintain a refreshing feeling.

As the flavoring agent, peppermint, mint such as spearmint, winter green, methyl salicylate, eugenol, melon, strawberry, orange, vanillin, etc. may be used. In general, the flavoring agent may be used in an amount of 0.001 to 10% by weight based on the total weight of the composition.

In addition, a sweetening agent may be added to the composition of the present invention in order to overcome the basic taste that the formulation may have. The sweetener may play a role in sustaining the generation of saliva by providing a continuous taste while remaining in the oral cavity.

As a sweetener, saccharin, sucralose, sugar, xylitol, sorbitol, lactose, mannitol, maltitol, erythritol, aspartame, taurine, saccharin salt, D-tryptophan, etc. can be used by 1 type or a mixture of 2 or more types. Among the saccharin salts, sodium saccharin is the most widely used. The amount of the sweetener is generally used in the range of 0.001 to 20% by weight of the total weight of the composition.

As the medicinal agent used for oral hygiene, ingredients effective in preventing tooth decay, gum disease, tartar deposition, and whitening may be used. Drugs used for the purpose of preventing tooth decay include compounds recognized as safe substances by the US Food and Drug Administration, including fluoride ions. Compounds that can be used as a source of fluoride ions include sodium fluoride, sodium monofluorophosphate, tin fluoride, and ammonium fluoride. The content of fluorine may vary in the amount used depending on the country, but it is common to use one or a mixture of two or more of these sources to preferably have a fluorine ion concentration in the range of 850 to 1500 ppm. Remineralizing agents can also act as a caries preventative. Remineralization plays a role in regenerating and restoring hydroxyapatite, a major component of teeth. The main components of hydroxyapatite are composed of divalent calcium cations and phosphate anions. Therefore, if calcium ions and phosphate ions are supplied at the same time or contain one or more calcium divalent ions or phosphate anions so as to move the chemical equilibrium in the oral cavity to the side where hydroxyapatite is produced, it may be a remineralizing agent. Substances providing calcium and phosphorus include hydroxyapatite, dibasic calcium phosphate, calcium chloride, casein phospeptide, calcium glycerophosphate, monosodium phosphate, dibasic sodium phosphate, trisodium phosphate, potassium monobasic, Potassium diphosphate, potassium triphosphate, and the like are included therein. In general, the remineralizing agent is preferably used in the range of 0.001 to 20 wt% of the total composition. If it is less than 0.001% by weight, the remineralization effect is reduced, and if it is more than 20% by weight, the original properties of the formulation are lost. One of the purposes of using oral hygiene products is to prevent gum disease in advance as well as alleviate the ongoing periodontal disease through sterilization or anti-inflammatory action on harmful microorganisms living in the oral cavity. For this purpose, known antibacterial agents such as isopropylmethylphenol, cyclohexidine, cetylpyridinium chloride, xanthorizol, etc. may be used, and for anti-inflammatory action, vitamins, enzymes, aminocaproic acid, allatoin and derivatives thereof can be used The active agent may contain 0.005% to 5% by weight. If the drug content is less than 0.005, it is difficult to show the drug effect, and if it contains more than 5 wt%, there is a disadvantage of changing the taste of the basic base. In addition to gum disease, hydrogen peroxide, carbamide peroxide, calcium peroxide, etc., which have a whitening effect, may be used, and sodium pyrophosphate, sodium acid pyrophosphate, potassium pyrophosphate, sodium metaphosphate, etc. are used to obtain the effect of inhibiting tartar deposition. In general, these agents are used in the range of 0.001 to 10% by weight of the total weight of the composition.

Phosphoric acid, sodium phosphate, citric acid, sodium citrate, succinic acid, sodium succinate, tartaric acid, sodium tartrate, etc. can be used as the pH adjuster, and the acidity of the oral composition is generally 5 to 8.

As a preservative, benzoic acid, methylparaben, propylparaben, sodium benzoate, etc. can be used.

Foaming agents include sodium alkyl sulfate, sodium lauryl sulfate, alkyl salucosinate, lauryl salucosinate, cocoyl glutamate sodium salt, myrisritoyl glutamate sodium salt, cocamidopropyl betaine, sucrose fatty acid ester, sorbitan fatty acid ester , an anionic, amphoteric and nonionic surfactant such as a copolymer (poloxamer) of polyoxyethylene polyoxypropylene can be used alone or in combination of two or more.

Titanium oxide is used as the brightening agent, and is generally used in an amount of 0.1% to 2% by weight.

The pump-type toothpaste composition of the present invention reduces the length of the toothpaste remaining in the outlet after pumping by 50% or more, preferably 70% or more, more preferably 90% or more, compared to the case where the acrylic polymer is not included. characterized in that

The method for preparing the toothpaste composition of the present invention may be prepared according to a method conventionally prepared in the industry, and preferably may be prepared in the form of a gel.

The term 'gel' is used as a concept to distinguish between a liquid toothpaste of a conventional thin formulation and a paste toothpaste of high viscosity. The gel phase is a formulation that is different from the existing liquid formulation, and it means a formulation having a high degree of stickiness and viscosity compared to a liquid toothpaste. The gel toothpaste of the present invention has elasticity and refers to a formulation with firmness compared to liquid toothpaste. In addition, the gel toothpaste of the present invention has a lower viscosity than the paste-type toothpaste, so that it can be easily discharged through the discharge port of the pump type container.
