Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a composition for oral use containing diamond particles, and more specifically to a composition for the oral cavity, comprising diamond particles and silica particles. This application claims priority to Japanese Patent Application No. 2013-120778 filed on Jun. 7, 2013. The disclosure in the specification and/or the drawings of the patent application is incorporated herein by reference. 
       BACKGROUND ART 
       [0002]    Tooth discoloration results from deposition on the teeth of chromogenic substances called “stains.” This causes a serious problem in terms of aesthetics. As a means for removing stains, a common method is that a composition for oral use, such as a dentifrice composition containing a dental abrasive, is held in the mouth with a tool such as a toothbrush, and the teeth are brushed. The composition for oral use is expected to not only efficiently remove stains but also make the tooth surfaces smooth after use, thereby making it difficult for stains or the like to adhere to the teeth and thus providing an effect of keeping the teeth beautiful. 
         [0003]    It is generally thought that a composition for oral use comprising a dental abrasive with a higher abrasive power has greater cleaning ability and smoothing. However, when the abrasive power is high, there is a risk that the abrasion on the teeth may be more than necessary. In this case, although stains may be removed, the teeth themselves will wear away over time. When the tooth surface wears away too much, the dentin may be exposed, which may cause hypersensitivity. Further, because the exposed dentin has poor resistance to acid, tooth decay may be promoted. Further, even if a composition has high abrasive power, it is difficult to predict whether the composition can make the tooth surface smooth, and it may cause more abrasion than necessary on the tooth surface, resulting in a rough surface. 
         [0004]    As described above, the composition for oral use must have stain removal ability (hereinafter also referred to as “cleaning ability”) and the ability to make the tooth surface smooth (hereinafter also referred to as “smoothing”).

     DESCRIPTION OF EMBODIMENTS 
       [0009]    The present invention is described in more detail below. 
         [0010]    The composition for oral use of the present invention comprises diamond particles and silica particles. 
         [0011]    The diamond particles preferably have an average particle size (particle diameter corresponding to 50% in the cumulative particle size distribution (i.e., 50% cumulative diameter): d50) of 0.5 to 5 μm, more preferably 1 to 4 μm, and even more preferably 2 to 3 μm. 
         [0012]    Further, the diamond particles preferably have a 99% cumulative diameter (d99) of 7 μm or less, more preferably 5 μm or less, and even more preferably 4.5 μm or less. 
         [0013]    Further, the diamond particles preferably have a 10% cumulative diameter (d10) of 0.1 μm or more, more preferably 0.5 μm or more, even more preferably 1 μm or more, and still more preferably 1.8 μm or more. 
         [0014]    With respect to the above conditions (preferable ranges) of d50, d99, and d10, diamond particles that satisfy the conditions of d50 are preferable. Diamond particles that satisfy the conditions of d50 and d99 are more preferable, and diamond particles that satisfy the conditions of d50, d99, and d10 are even more preferable. 
         [0015]    As such diamond particles, natural or synthetic products can be used. Synthetic products can be produced, for example, by a known method, such as a high-temperature, high-pressure synthesis method, a chemical vapor deposition method, a detonation synthesis method, or an ultrasonic cavitation method. 
         [0016]    The cumulative diameter of the diamond particles as referred to herein is a value determined based on the Coulter Principle (the electrical sensing zone method) using water as a dispersion (i.e., a value obtained using a Coulter counter). This value can be measured, for example, by using a Multisizer 3 Coulter (produced by Beckman Coulter, Inc.) 
         [0017]    The silica particles contained in the composition for oral use of the present invention may be, for example, silica known to be used for compositions for oral cavity and synthesized by a wet method or a dry method. Since the balance between cleaning ability and abrasiveness of silica synthesized by wet methods is suitable for use in the present invention, silica synthesized by wet methods is preferable. Examples of wet methods include precipitation methods and gel methods. Silica obtained by wet methods can be roughly classified into precipitated silica synthesized by precipitation methods and gelled silica synthesized by gel methods. In the present invention, any type of silica can be used. Precipitated silica is often more preferable than gelled silica, but this is not limitative. The phrase “often more preferable” means that precipitated silica often has preferable values in terms of the average particle size and oil absorption described below, and BET specific surface area. 
         [0018]    Commercially available silica products can be used as silica particles used in the present invention. Examples of precipitated silica particles include Aerosil, Ultrasil, Carplex (all produced by Evonik Degussa), Aerosil (produced by Japan Aerosil Co., Ltd.), Zeodent (produced by Huber Corporation), Excelia, Reolosil (both produced by Tokuyama Corporation), Syilsia (produced by Fuji Sylsia Chemical Ltd.), Sorbosil (produced by Ineos Silicas Ltd.), Denka fused silica (produced by Denki Kagaku Kogo Kabushiki Kaisha), Nipsil and Nipgel (both produced by Tosoh Silica Corporation), Zeosil, Tixosil (produced by Solvay S.A.), and the like. Among these, for example, Zeodent (produced by Huber Corporation), Sorbosil AC (produced by PC Corporation), and Texosil (produced by Phodia Co., Ltd.), all of which are precipitated silica particles, are preferable. 
         [0019]    The silica particles preferably have an average particle size (d50) of 0.5 to 20 μm, more preferably 1 to 15 μm, even more preferably 2 to 13 μm, and still even more preferably 3.5 to 13 μm. The silica particles preferably have an oil absorption (linseed-oil absorption according to JIS K5101) of 10 to 200 (mL/100 g), more preferably 20 to 150 (mL/100 g), even more preferably 25 to 140 (mL/100 g), and still even more preferably 30 to 135 (mL/100 g). 
         [0020]    The silica particles contained in the composition for oral use of the present invention preferably comprise a combination of silica particles having different properties. Although a combination of two or more types (for example, three, four, or five types) of silica particles may be used, using a combination of two types of silica particles having different properties is the most preferable. Examples of the combination of two types of silica particles having different properties are shown below. When the two types of silica particles used in combination are termed “first silica particles” and “second silica particles,” respectively, the first silica particles preferably have an average particle size (d50) of 3 to 5.5 μm (more preferably in the range of 3.5 to 5 μm), and an oil absorption (linseed oil absorption according to JIS K5101) of 20 to 80 (mL/100 g) (more preferably in the range of 30 to 70 (mL/100 g)). The second silica particles preferably have an average particle size (d50) of 6 to 15 μm (more preferably in the range of 6 to 12 μm) and an oil absorption (linseed oil absorption according to JIS K5101) of 90 to 150 (mL/100 g) (more preferably in the range of 90 to 140 (mL/100 g)). 
         [0021]    The average particle size (d50) of silica referred to herein is a value determined by laser diffraction scattering using water as a dispersant. The value can be determined, for example, by using a Malvern Mastersizer based on the principle of Fraunhofer diffraction using a low-power He/Ne laser. 
         [0022]    The composition for oral use of the present invention preferably comprises diamond particles in an amount of 0.01 to 0.5 mass %, and more preferably 0.05 to 0.2 mass %. The composition for oral use of the present invention preferably comprises the silica particles in an amount of 1 to 35 mass %, and more preferably 2 to 30 mass %. 
         [0023]    The composition for oral use of the present invention preferably comprises the silica particles in an amount of 1 to 35 parts by mass, and more preferably 5 to 30 parts by mass, per 0.01 to 0.5 parts by mass (preferably 0.05 to 0.2 parts by mass) of the diamond particles. In particular, the silica particles are more preferably used in an amount of 15 to 30 parts by mass per 0.01 to 0.5 parts by mass of the diamond particles. The silica particles are particularly preferably used in an amount of 20 to 30 parts by mass per 0.05 to 0.2 parts by mass of the diamond particles. 
         [0024]    When a combination of the first silica particles and second silica particles is used as the silica particles, the second silica particles are preferably used in an amount of 0.5 to 25 parts by mass, more preferably 1 to 20 parts by mass, even more preferably 1 to 10 parts by mass, still more preferably 1 to 5 parts by mass, even still more preferably 1.5 to 4.5 parts by mass, particularly preferably 2 to 4 parts by mass, and most preferably 2.5 to 3.5 parts by mass, per part by mass of the first silica particles. 
         [0025]    The amount of the first silica particles in the composition is preferably 2 to 8 mass %, and more preferably 3 to 7 mass %, and the amount of the second silica particles in the composition is preferably 2 to 25 mass %, and more preferably 5 to 22 mass %. 
         [0026]    The composition for oral use of the present invention can be produced by using a known method. The composition for oral use of the present invention can be used for teeth and dentures, and can be formed into dentifrices in various forms by usual methods, such as paste dentifrices, powder dentifrices, cream dentifrices, gel dentifrices, liquid dentifrices, pastes, and the like. In particular, paste dentifrices, powder dentifrices, cream dentifrices, or gel dentifrices are preferable.

       EXAMPLES 
       [0039]    The present invention is described below in more detail with reference to Examples but is not limited to these. The diamond particles used in the Examples below were purchased from Microdiamant, and the silica particles used in the Examples were purchased from J. M. Huber Corporation. 
       Preparation of the Composition for Oral Use 
       [0040]    Compositions (pastes) for oral use in Examples 1 to 12 and Comparative Examples 1 to 4 were prepared according to the formulations shown in Tables 1 and 2 below. Specifically, starting materials other than diamond particles, abrasive silica particles, a flavoring agent, and foaming agents (sodium sulfosuccinate and sodium lauryl sulfate) were mixed. Diamond particles and abrasive silica particles were added, and the resulting mixture was stirred and homogenized. Further, the flavoring agent was added and the resulting mixture was stirred and homogenized. Lastly, the foaming agents were added and the resulting mixture was stirred and homogenized (this process also functioned as defoaming treatment). All numerals for the components in Tables 1 and 2 are by mass %. 
         [0041]    Two types of commercially available precipitated silica products were used as silica particles. These were termed “silica particles a” and “silica particles b.” The specifications of these commercially available silica products are as follows. Silica particles a have an average particle size (d50) of 3.5 to 5 μm, and an oil absorption (linseed oil absorption according to JIS K5101) of 30 to 70 (mL/100 g). Silica particles b have an average particle size (d50) of 6 to 12 μm, and an oil absorption (linseed oil absorption according to JIS K5101) of 90 to 135 (mL/100 g). 
         [0042]    The diamond particles used had an average particle size (d50) of 2.4 to 3 μm (about 2.8 μm), a d10 of 1.8 μm or more, and a d99 of 4.5 μm or less. 
         [0043]    The particle size of silica particles (d50) is determined by using a Malvern Mastersizer based on the principles of Fraunhofer diffraction using a low-power He/Ne laser. The cumulative diameter of the diamond particles is determined by using a Multisizer 3 Coulter Counter (produced by Beckman Coulter, Inc.) 
       Evaluation of Compositions for Oral Use 
       [0044]    The obtained compositions for oral use were evaluated for cleaning ability and smoothing in the following manner. Table 2 shows the results. 
       Method for Evaluating Cleaning Ability 
       [0045]    A bovine enamel tooth fragment was cut out to a size of 3 mm in length×3 mm in width using an automatic precision cutter. Two pieces of the fragment were embedded per block using a dental polymer resin (Orthofast resin, produced by GC Corporation). After drying, the surface of the tooth fragment was mirror-polished with an automatic polishing device and polishing paper, washed with ion-exchanged water, and dried. To determine the initial color difference, L*, a*, and b* values were measured in a 1.8-mm-diameter measurement area using a colorimeter (CR-241, produced by Konica Minolta Sensing, Inc.) (The L, a, and b values thus obtained were termed L 0 , a 0 , and b 0 , respectively.) 
         [0046]    Further, the surface of the tooth fragment subjected to the initial color difference measurement was etched by sequentially immersing 0.2M hydrochloric acid, aqueous saturated sodium carbonate solution, distilled water, 1% (v/v) phytic acid, and distilled water in this order. 
         [0047]    Subsequently, stains were applied to the surface of the etched tooth fragment in the following manner. The staining fluid to be used was prepared by placing four commercially available tea bags into about 1.2 L of hot water, boiling the water for 10 minutes, cooling the resulting black tea solution to room temperature, and adding 3.4 g of commercially available instant coffee and 2.5 g of type II porcine stomach mucin (produced by Sigma-Aldrich Co. LLC). 
         [0048]    The tooth fragment was placed on a stain application machine. The staining fluid was added and the machine was rotated to continue a stain application treatment for 5 to 6 days. The staining fluid was replaced with new staining fluid once a day. The tooth fragment was then treated with a treatment liquid, which was prepared by adding 1 g of ferric chloride to the staining fluid, for 1 or 2 days until the L* value became 30 or less. After the tooth fragment was washed with ion-exchanged water and dried, the color difference was measured (L 1 , a 1 , b 1 ). 
         [0049]    The stained tooth fragment was set in an ISO-standard brushing machine. The stained tooth fragment was brushed for 3,000 reciprocal strokes with a load of 150 g at a rate of 150 rpm in a 3-fold dilution (60 ml) of each of the compositions for oral use obtained in the Examples and Comparative Examples. After drying, the color difference was measured (L 2 , a 2 , b 2 ). The stain removal ability (GE) was calculated according to the following formula (rounded off to the nearest whole number) and evaluated. Table 2 shows AE as the value reflecting cleaning ability. 
         [0000]      Δ E =(Δ E   1   /ΔE   0 )×100
 
         [0000]    provided, however, that 
         [0000]      Δ E   1 ={( L   2   −L   1 ) 2 +( a   2   −a   1 ) 2 +( b   2   −b   1 ) 2 } 1/2  
 
         [0000]      Δ E   0 ={( L   2   −L   0 ) 2 +( a   2   −a   0 ) 2 +( b   2   −b   0 ) 2 } 1/2  
 
         [0000]    (That is, ΔE 1  is equal to the square root of the sum of the square of (L 2 −L 1 ), the square of (a 2 −a 1 ), and the square of (b 2 −b 1 ), and ΔE 0  is equal to the square root of the sum of the square of (L 2 −L 0 ), the square of (a 2 −a 0 ), and the square of (b 2 −b 0 ).) 
       Evaluation of Smoothness 
       [0050]    A bovine enamel tooth fragment was cut out to a size of 3 mm in length×6 mm in width using an automatic precision cutter. One piece of the fragment was embedded in a dental polymer resin (Orthofast resin, produced by GC Corporation) per block. After drying, the surface of the tooth fragment was mirror-polished with an automatic polishing device and polishing paper. 
         [0051]    The surface of the tooth fragment was etched by sequentially immersing 0.2M hydrochloric acid, distilled water, aqueous saturated sodium carbonate solution, distilled water, and 1% (v/v) phytic acid in this order. 
         [0052]    After tape (Scotch brand tape, 10 mm; Sumitomo 3M) was applied to half of the tooth surface to protect the surface, the tooth fragment was set in an ISO-standard brushing machine. The tooth fragment was brushed for 3,000 reciprocal strokes in a 3-fold dilution (60 mL) of the compositions for oral use of the Examples and Comparative Examples with a load of 150 g at a rate of 150 rpm. 
         [0053]    After brushing, the arithmetic-average roughness (Ra) per unit area of 500 μm×500 μm was measured with a shape-measuring laser microscope (VK-8700, produced by Keyence Corporation) and evaluated. The Ra of the surface protected with the tape was termed Ra before testing. The smoothness was calculated according to the following formula. 
         [0000]      Smoothness=(Ra before testing−Ra after testing)/Ra befoe testing)×100
