Description

Oral biological film remover and composition for oral cavity
Technical field
The present invention relates to the biomembranous oral biological film remover and composition for oral cavity that chemically remove efficiently as the reason of dental caries.
Background technology
In the past, removed technology as the dental plaque (tartar) in dentifrice, the physical property removing that the cleaning agent with grinding agent etc. causes, the biochemical removing etc. that enzyme etc. cause.
When use cleaning agent removes, needing to increase the amount of grinding agent in order to play its effect, improving hardness, but rise along with abrasive power, have the hazardness being easy to produce tooth and gingival lesions etc., irritating possibility.On the other hand, in order to stable mixed enzyme, need and use various stabilizing agent, having the situation of the use senses such as impact foaming and taste.
In addition, in recent years, if tartar can be caught as biomembrane, removing biomembrane, then more effectively can remove denude.For the intraoral biomembrane of removing, not only use the physical method of toothbrush useful, and the chemical method of the biomembrane removing that toothbrush cannot be able to be touched is also useful.Biomembrane is made up of the coaggregant of various oral cavity bacterium and extracellular polysaccharide class.Therefore, as chemistry removing method, there will be a known the erythritol that uses and have and suppress aggregation effect and, use the protease of enzyme or the method for glucanase, change dextranase etc. that decompose extracellular polysaccharide, but the space that its effect is also improved.
In addition, known surface activating agent has cleaning function, can as detergent use in composition for oral cavity.In this case, known lauryl sulfoacetate sodium is the activating agent (patent documentation 1: Japanese Patent Laid-Open 6-72836 publication) without the distinctive stimulation of anionic surfactant.
But, present situation is all the time surfactant, from its osmosis, the viewpoint that clean surface turns into is considered, although only there is slight effect but think that it has tartar removing effect, but there is when not thinking and be used alone surfactant sufficient tartar and even biomembrane removing effect.
In addition, disclose in patent documentation 2 (Japan Patent spy table 2008-519043 publication) and use the alkali metal salts or ammonium salt of sulfoacetic acid alkyl and the method for water-soluble zinc salt, but sulfoacetic acid alkyl salt is the constringent compound for reducing zinc salt, do not show biomembranous removing effect.Further, patent documentation 3 (Japanese Patent Laid-Open 9-508120 publication) discloses the composition for oral cavity of the toothpaste containing lauryl sulfoacetate sodium as the stimulation alleviated oral mucosa, but does not relate to raising biomembrane removing effect.
On the other hand, known condensed phosphate has the effect (patent documentation 4: Japanese Patent Laid-Open 9-175966 publication) of the removing tooth spot of chemical, but has sufficient tartar and biomembrane removing effect when not thinking and be used alone condensed phosphate.

Summary of the invention
The problem that invention will solve
Problem of the present invention provides a kind of in view of the foregoing chemically to remove biomembranous oral biological film remover as the reason of dental caries and composition for oral cavity efficiently.
Solve the means of problem
The present invention, in order to the problem reaching the invention described above is through further investigation, found that by and can solve above-mentioned problem with (A) alpha-alkene sulfonate and (B) condensed phosphate (B-1) and/or amphoteric surfactant (B-2).
Specifically, the present inventors finds, by combination (A) alpha-alkene sulfonate and (B) condensed phosphate (B-1), the removing effect of oral biological film can be significantly improved, and the distinctive bitterness of (A) composition can be suppressed, suitable foaming (I invention) can be given in addition.
In I invention, when the mass ratio of (A) composition and (B-1) composition, particularly (A)/(B-1) is in the scope of 0.1 ~ 10, special and work synergistically, strengthen the effect of dispersion removing oral biological film.In addition, the bitterness being derived from (A) composition can be suppressed, give the suitable foaming caused by (A) composition.
That is, as shown in aftermentioned embodiment and comparative example, when being used alone the alpha-alkene sulfonate of (A) composition, the biomembranous removal rate of making is stuck in less than 70%.In addition, even if the biomembrane removal rate in discovery condensed phosphate (B-1) is less than 50%, not there is sufficient biomembrane removing effect yet, but time also with (A) composition and (B-1) composition, unexpectedly two kinds of composition co-action, can obtain sufficient biomembrane removing effect.In addition, find in this case, even if by the anionic surfactant beyond (A) composition, such as sodium lauryl sulfate, to use with condensed phosphate, also cannot obtain sufficient biomembrane removing effect, above-mentioned biomembrane removing effect be (A) composition with (B-1) composition and when special action effect.Further, alpha-alkene sulfonate has bitterness, in the past, although disclose its use in the literature, reality is the material belonging to avoidance in oral preparation, and the present inventors finds (A) composition and (B-1) composition and the used time, the bitterness being derived from (A) composition can be suppressed, give good use sense, maintain the suitable foaming that (A) composition causes, make and be applicable to the actual preparation used, thus complete the present invention.
In addition, the present inventors is in order to reach the problem of the invention described above through further investigation, found that by combination (A) alpha-alkene sulfonate and (B) amphoteric surfactant (B-2), the removing effect of oral biological film can be significantly improved, and the distinctive bitterness of (A) composition can be suppressed, suitable foaming (II invention) can be given in addition.
In (II) invention, (A) composition and (B-2) composition, when particularly the mass ratio of (A)/(B-2) is in the scope of 0.2 ~ 8, special and work synergistically, strengthen the effect of dispersion removing oral biological film.In addition, the bitterness being derived from (A) composition can be suppressed, give the suitable foaming caused by (A) composition.
That is, as shown in aftermentioned embodiment and comparative example, when being used alone the alpha-alkene sulfonate of (A) composition, the biomembranous removal rate of making is stuck in less than 70%.In addition, although the biomembrane removal rate in discovery amphoteric surfactant (B-2) is less than 50%, not there is sufficient biomembrane removing effect, even if with itself and other surfactant is used, do not think that biomembrane can be made to remove effect to be improved yet, but by (A) composition and (B-2) composition and the used time, unexpectedly two kinds of compositions work synergistically, can obtain sufficient biomembrane removing effect by surfactant system.In addition, find in this case, even if by the anionic surfactant beyond (A) composition, such as sodium lauryl sulfate, to use with amphoteric surfactant, also sufficient biomembrane removing effect cannot be obtained, special action effect when above-mentioned biomembrane removing effect is and uses (A) composition and (B-2) composition.Find further, alpha-alkene sulfonate has bitterness, although disclosed its use in the literature in the past, but in fact its use is avoided, but when and with (A) composition and (B-2) composition time, the bitterness being derived from (A) composition can be suppressed, give good use sense, in addition can maintain the suitable foaming that (A) composition causes, make and be applicable to the actual preparation used, complete the present invention.
In II invention, when mixing (C) quaternary ammonium salt, (D) xylitol and/or erythritol further, more excellent oral biological film removing effect can be given specifically.
In this case, more preferably containing (A) composition, (B-2) composition, Dentrifice composition further preferably containing (C) composition, or more preferably containing (A) composition, (B-2) composition, the mouthrinse composition further preferably containing (D) composition.
Therefore, the present invention (I invention) provides following oral biological film remover and composition for oral cavity.
