Description

은을 함유한 치약{TOOTHPASTE INCLUDING SILVER}Silver Toothpaste {TOOTHPASTE INCLUDING SILVER}

본 발명은 은을 함유한 치약에 관한 것으로서, 특히 은을 나노입자의 크기로 만들어 표면적을 넓게하여 살균, 항균 효과가 더욱 크게 할 수 있는 은을 함유한 치약에 관한 것이다.The present invention relates to a toothpaste containing silver, and more particularly, to a toothpaste containing silver which can increase the surface area by making silver the size of nanoparticles, which can further increase sterilization and antibacterial effects.

최근에 나노 미터 크기의 구조나 입자에 대한 합성방법 및 분석방법 등이 발전되어오면서 이 기술을 이용한 산업의 응용이 이루어지고 있다. 반도체 등의 전자산업뿐 아니라 바이오 및 실생활에 필요한 각종 소재에까지 그 파급 효과가 미치고 있다.Recently, the development of nanometer-sized structures, synthesis methods and analysis methods for particles have been developed, and industrial applications using this technology have been made. Not only the electronics industry, such as semiconductors, but also to the various materials necessary for bio and real life has its ripple effect.

이중 나노 입자는 합성 또는 분쇄 등의 생산 기술이 발전하면서 다양한 물질을 나노 크기에 저가 대량생산이 가능하게 되었다. 이 기술을 이용하여 향기가 나는 천을 만들고 나노 입자의 특이한 광적 성질을 이용하여 나노입자 태양열 전지나광분해를 이용한 코팅이 자동차나 고층 빌딩용 유리창 등에 사용을 목적으로 개발되고 있다.As nanoparticles have advanced production techniques such as synthesis or pulverization, various nanomaterials can be mass-produced at low cost in large quantities. Using this technology to create a scented fabric and using the unique optical properties of nanoparticles, nanoparticle solar cells or photocatalytic coatings are being developed for use in automobiles and glass windows for skyscrapers.

최근 들어 금이나 은 같은 인체에 무해하면서 나노크기에서 생겨나는 특이한 성질을 이용하여 다양한 분야에 응용의 가능성이 점점 확산되어 왔다. DDS(Drug Delivery System)이나 냉각수 살균, 의류용 섬유소재 또는 산업용 페인트나 비누 등의 생활용품에 까지 그 응용에 대해 연구중이다.In recent years, the possibility of application in various fields has been gradually spread using the unique properties that occur in nano-size while being harmless to the human body such as gold or silver. We are studying the application to DDS (Drug Delivery System), cooling water sterilization, textile material for clothing or household goods such as industrial paint or soap.

따라서, 은을 이용한 미세 입자 또는 나노 입자의 경우 우수한 항균력이 밝혀지면서 많은 응용 가능성이 제안되었다. 정수기에 사용하여 살균작용을 하거나 유아용품이나 내의, 신발용 섬유소재, 샴푸, 화장품 등의 생활용품으로 적용이 가능할 것으로 제안되어지고 있다.Therefore, in the case of fine particles or nanoparticles using silver has been found excellent antimicrobial power has been proposed many applications. It is proposed to be used as a water purifier to sterilize or to be applied to household goods such as baby products, underwear, textile materials for shoes, shampoo and cosmetics.

예로부터 우리나라 사람들은 은 반지나 은 목걸이를 착용함으로써 제독의 효과나 몸에 병이 든 것을 은의 변색을 통하여 예방하였다. 또한 고대 그리스인들은 은 항아리에 물을 저장하였고 미국 개척시기에 미국인들은 은 동전이 필수 소지품중 하나로 우유를 짜낸후에 은 동전을 넣어 살균하여 마셨다.Since ancient times, Koreans have worn silver rings or silver necklaces to prevent the effects of admiral and sickness through the discoloration of silver. Ancient Greeks also stored water in silver jars, and during the American pioneering period, Americans squeezed milk into silver coins as one of the essential belongings and drank them with silver coins.

은의 이러한 살균, 항균 효과는 과학적으로도 보고가 되었다. 은은 바이러스, 박테리아, 곰팡이, 세균 등의 세포 속으로 쉽게 침투하여 호흡할 때 필요한 효소의 기능을 정지시켜 질식 시킴으로써 이들을 죽게 한다. 일반 박테리아, 곰팡이균 등은 물론 일반 항생제로 잘 듣지않거나 항생제에 내성을 가진 바이러스까지 약 650여종의 유해 세균을 살균할 수 있는 강력한 살균력을 가진다.The bactericidal and antimicrobial effects of silver have been reported scientifically. Silver easily penetrates into cells such as viruses, bacteria, fungi and bacteria and kills them by suffocating by stopping the function of the enzymes needed to breathe. It has strong bactericidal power to sterilize about 650 kinds of harmful bacteria such as general bacteria, fungi, etc., as well as viruses that are hardly heard by antibiotics or resistant to antibiotics.

그러나, 종래에 살균제나 항균제 또는 치약등에 사용되는 살균소독제는 독성이 함유되어 있어 그 사용에 있어 안정성에 많은 문제점이 발생되고 있다.However, the disinfectant disinfectant conventionally used in disinfectants, antibacterial agents, toothpastes, and the like contains toxicity, causing many problems in stability in its use.

본 발명은 상기와 같은 문제점을 개선하기 위하여 창출된 것으로서, 은을 나노입자의 크기로 만들어 표면적을 넓게하여 살균, 항균 효과가 더욱 크게 할 수 있는 은을 함유한 치약을 제공함에 그 목적이 있다.The present invention has been made to improve the above problems, the object of the present invention is to provide a toothpaste containing silver which can increase the surface area by making the size of the nanoparticles of silver to further increase the sterilization and antibacterial effect.

도 1은 원형으로 만들어진 은 나노 입자의 TEM 를 도시한 도면.1 shows a TEM of silver nanoparticles made in a circle.

도 2는 본 발명에 따른 은 나노입자의 양자 효과에 의해 발생되는 것을 도시한 도면.Figure 2 shows that generated by the quantum effect of the silver nanoparticles according to the present invention.

상기의 목적을 달성하기 위하여 본 발명에 따른 은을 함유한 치약은,In order to achieve the above object, the toothpaste containing silver according to the present invention,

기제와 기포제를 포함하여 조성된 치약에 있어서,In a toothpaste comprising a base and a foaming agent,

항균성을 지닌 은 나노입자를 첨가하여 조성되는 점에 그 특징이 있다.It is characterized by the addition of silver nanoparticles having antimicrobial properties.

여기서, 상기 은 나노입자의 크기는 수㎛ ~ 수십㎚까지 형성되는 점에 그 특징이 있다.Here, the size of the silver nanoparticles is characterized in that it is formed from several ㎛ to several tens of nm.

이와 같은 본 발명에 의하면, 은을 나노입자의 크기로 만들어 표면적을 넓게하여 살균, 항균 효과가 더욱 크게 할 수 있다.According to the present invention as described above, silver can be made into the size of nanoparticles to increase the surface area, so that the bactericidal and antimicrobial effects can be further increased.

이하 첨부된 도면을 참조하면서 본 발명의 실시 예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 원형으로 만들어진 은 나노 입자의 TEM 를 도시한 도면이다. 이에 도시된 바와 같이, 은 나노입자는 수 마이크론에서 수십 나노미터까지 다양한 크기의 미세 입자의 형성이 가능하다.1 is a diagram illustrating a TEM of silver nanoparticles made in a circle. As shown therein, the silver nanoparticles can form fine particles of various sizes ranging from several microns to several tens of nanometers.

그리고, 상기 마이크론 크기에서는 표면에만 코팅을 하여 형성할 수 있다.In addition, the micron size can be formed by coating only the surface.

한편, 상기 은 나노입자의 제조방법은 일반적으로 기계식 방식의 얼티마이저나 밀링 등의 분쇄기법을 이용한 방법과 화학적 방법이나 물리적 방법들도 다양하게 발전되고 있다. 따라서, 상기 방법들에 의해 서브마이크론 이하의 입자가공이 대량생산으로까지 가능해지고 있다.On the other hand, the production method of the silver nanoparticles are generally developed in a variety of methods, such as a mechanical method of the optimizer or milling, such as milling methods, chemical methods and physical methods. Thus, the above-described methods enable sub-micron particle processing up to mass production.

여기서, 은이나 은 복합물질을 나노 입자로 만들면 표면적이 넓어져서 살균, 항균 효과가 더욱 커지게 된다.Here, when silver or silver composite material is made into nanoparticles, the surface area becomes wider, and the sterilization and antibacterial effect is further increased.

도 2는 본 발명에 따른 은 나노입자의 양자 효과에 의해 발생되는 것을 도시한 도면이다. 이에 도시된 바와 같이, 입자가 나노미터 크기일 경우 양자효과에 의해서 입자에 한정(confine)되는 파장에 따라 그 에너지인 hv를 흡수하여 전자와 정공을 만들어 기전력을 발생시키거나 주위의 물이나 유기물을 산화, 환원시킬 수 있다.2 is a view showing that generated by the quantum effect of the silver nanoparticles according to the present invention. As shown in the figure, when the particle is nanometer size, it absorbs the energy hv according to the wavelength confined to the particle by the quantum effect to generate electrons and holes to generate electromotive force, or to generate water or organic matter. It can be oxidized and reduced.

여기서, 상기 은을 나노 크기로 하면 나노 입자 특유의 광학적 특성으로 인해 자외선을 흡수하여 유기물을 전기분해 하는 성질을 가진다.Herein, when the silver is nano-sized, the organic material absorbs ultraviolet rays and electrolyzes the organic material due to the unique optical properties of the nanoparticles.

따라서, 상기와 같은 크기를 가지고 항균 기능을 가지는 은 입자를 미세 가루로 만들어 적용하게 되는데, 은은 금과 마찬가지로 인체에 유입되어도 인체에 무해한 귀금속 종류이다.Therefore, silver particles having the same size and having an antimicrobial function are applied to make fine powder, and silver is a kind of precious metal which is harmless to the human body even when introduced into the human body like gold.

여기서, 순수한 은은 인체에 무해하며 은과 다른 입자와의 복합체도 그 종류에 따라 인체에 무해하다. 실리콘 나노 입자에 순수 금속 은 입자가 결합된 은 복합 나노 입자의 경우 FDA에서 인체에 무해하다는 검증을 받았다.Here, pure silver is harmless to the human body, and the complex of silver and other particles is also harmless to the human body depending on its kind. Silver composite nanoparticles in which pure metal silver particles are combined with silicon nanoparticles have been verified by the FDA as being harmless to humans.

은이 귀금속의 일종으로 가격이 비싸므로 적은 양의 은을 사용하여 효과적으로 사용하기 위해서는 크기를 작게 하는 것이 유리할 것이다. 나노 크기로 가면 나노 입자 특유의 광학적 특성으로 인해 자외선을 흡수하여 유기물을 전기분해 하는성질을 가진다.Since silver is a kind of precious metal and expensive, it may be advantageous to reduce the size in order to effectively use a small amount of silver. When it is nano sized, it has the property of absorbing ultraviolet light and electrolyzing organic material due to the unique optical properties of nano particles.

예로 TiO2를 이용한 나노 입자의 경우 이 효과가 특히 커서 태양열 전지뿐 아니라, 자외선 차단제나 자외선을 이용하여 스스로 깨끗해지는 스마트 윈도우(smart window)등에 사용된다.For example, in the case of nanoparticles using TiO 2 , this effect is particularly large, and is used not only for solar cells but also for smart windows that clean themselves by using a sunscreen or ultraviolet light.

그리고, 은의 강력한 살균력은 나노 입자의 크기로 만들었을 때 넓어진 표면적과 나노 입자만의 특성때문에 더욱 잘 드러난다. 또한, 은은 독성이 없어서 인체에 무해하다.And, silver's potent bactericidal power is more pronounced due to its large surface area and the unique properties of nanoparticles. In addition, silver is not toxic and harmless to the human body.

따라서, 이러한 기능을 이용하여 본 발명에 따른 일 실시 예로 치약을 만들었을 경우에 은 나노 입자의 살균, 탈취, 광분해 효과를 이용한 미백 효과를 기대할 수 있다.Therefore, when the toothpaste is made in one embodiment according to the present invention using such a function, a whitening effect using sterilization, deodorization, and photolysis effects of silver nanoparticles can be expected.

본 발명에 따른 은을 함유한 치약의 제조는 먼저 기제와 기포제를 포함하여 조성된 일반적인 치약에 있어서, 항균성을 지닌 은 나노입자를 첨가하여 조성된다.Preparation of the toothpaste containing silver according to the present invention is first prepared in the general toothpaste comprising a base and a foaming agent, by adding silver nanoparticles having antimicrobial properties.

상기 일반적으로 구성되는 치약의 조성물에는 기제, 결합제, 습윤제, 기포제 등으로 조성된다.Toothpaste composition is generally composed of a base, a binder, a humectant, a foaming agent and the like.

상기 기제로는 인산일수소칼슘, 함수실리카, 탄산칼슘, 함수알루미나등이 사용되며, 여기서 하나 또는 다수개를 혼합하여 사용하게 된다.As the base, calcium monohydrogen phosphate, hydrous silica, calcium carbonate, hydrous alumina, and the like are used, where one or more are mixed and used.

그리고, 상기 결합제로는 카르복시메틸셀룰로스 나트륨, 카라기난, 잔탄검, 폴리아크릴산염 등이 일반적으로 많이 사용되며, 여기서, 하나 또는 다수개를 혼합하여 사용하게 된다.As the binder, carboxymethyl cellulose sodium, carrageenan, xanthan gum, polyacrylate, and the like are generally used. Here, one or a plurality of them are mixed and used.

또한, 상기 습윤제로는 소르비톨액, 글리세린, 폴리에틸렌글리콜, 프로필렌글리콜 등의 다가알코올류를 단독 또는 혼합하여 사용할 수 있다.As the humectant, polyhydric alcohols such as sorbitol liquid, glycerin, polyethylene glycol, and propylene glycol may be used alone or in combination.

그리고, 기포제로는 음이온계면활성제인 알킬황산나트륨이나, 비이온성 계면활성제를 사용하게 된다.As the foaming agent, sodium alkyl sulfate, which is an anionic surfactant, or a nonionic surfactant is used.

상기와 같이 조성된 물질에 살균, 항균 효과가 있는 은 나노입자를 첨가하게 된다.Silver nanoparticles having a bactericidal and antimicrobial effect are added to the material formed as described above.

상기 은 미세입자나 나노입자의 살균,항균 효과를 최대한 발휘하기 위해서는 미세입자는 넓은 표면면적으로 인해서 그 물질의 특성을 가지고 치아에 오랫동안 머물러야 한다.In order to maximize the bactericidal and antimicrobial effects of the silver microparticles or nanoparticles, the microparticles have to stay in the tooth for a long time due to the properties of the material due to the large surface area.

일반적으로 은의 미세입자는 물질에 대한 흡착성이 좋다. 따라서, 순수 은이나 은 복합입자의 치아에 대한 흡착성은 치아를 닦은 후 오랜 기간동안 은의 살균, 항균 효과를 기대할 수 있을 것이다. 또한, 은 나노 입자에 의해 오랜 기간동안 미백효과를 볼 수 있을 것이다.Generally, silver fine particles have good adsorption to materials. Therefore, the adsorption of pure silver or silver composite particles to the teeth may be expected to antibacterial and antimicrobial effect of silver for a long time after cleaning the teeth. In addition, silver nanoparticles will be able to see the whitening effect for a long time.

한편, 상기 은의 나노입자를 치약뿐만아니라 계면활성제로 조성된 항균 세척제에 첨가하여 살균과 항균이 강하고 인체에 무해한 세척제를 제조하는데 적용할 수 있다.On the other hand, by adding the nanoparticles of silver to the antimicrobial cleaning agent composed of a surfactant as well as toothpaste, it can be applied to the preparation of a detergent that is strong in disinfection and antibacterial and harmless to human body.

본 발명은 도면에 도시된 실시 예를 참고로 설명되었으나, 이는 예시적인 것에 불과하며, 본 기술분야의 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시 예가 가능하다는 점을 이해할 것이다. 따라서, 본 발명의 진정한 기술적 보호 범위는 첨부된 특허청구범위의 기술적 사상에 의해 정해져야 할 것이다.Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

이상의 설명에서와 같이 본 발명에 따른 은을 함유한 치약은 은을 나노입자의 크기로 만들어 표면적을 넓게하여 살균, 항균 효과가 더욱 크게 할 수 있다.As described above, the toothpaste containing silver according to the present invention may increase the surface area by making silver the size of nanoparticles, thereby increasing the sterilization and antibacterial effects.
