しかしながら、フィチン酸を含有する組成物においては、フッ素イオンを供給し得る化合物が必要以上に存在すると、フィチン酸による美白効果や光沢付与効果が損なわれる傾向にあるため、上記特許文献1~3のいずれにおいても、かかる化合物の含有量を極力制限することが望ましいとされている。そのため、依然としてフィチン酸による効果を十分に発揮しながら、フッ素を効果的に歯へ吸着させることのできる口腔用組成物は、実現されるに至っていない。
また、フィチン酸を含有する組成物とフッ素イオンを供給し得る化合物の共存下では、上記特許文献4のような量でピロリン酸塩を含有させると、さらにフッ素の歯へ吸着効果が低下するおそれもあるため、さらなる検討を要する。
なお、収斂感とは、口腔内組織、とくに歯肉等の口腔内粘膜(舌を含む)の組織が必要以上に収縮してしまうような感触を意味し、人によっては粘膜周辺でざらつきを感じる感触である。きしみ感とは、歯と歯を接触させたり擦りあわせたりしたときに、必要以上の摩擦を感じるような、歯における物理的不快感を意味する。

被験者10名(男性5名、女性5名)が、歯ブラシに歯磨き組成物1gをとり、約2分間自由にブラッシングした。口をすすいだ後に収斂感を強く感じた被験者数をカウントした。かかる値が小さいほど、収斂感が良好に低減されていることを示す。
被験者10名(男性5名、女性5名)が、歯ブラシに歯磨き組成物1gをとり、約2分間自由にブラッシングした。口をすすいだ後にきしみを強く感じた被験者数をカウントした。かかる値が小さいほど、きしみを感じることのない使用感に優れることを示す。
表2に示す処方にしたがって、フッ素吸着量を測定するための液体口腔用組成物を調製した。次いで、下記方法にしたがって、フッ素吸着量を測定し、評価した。
結果を表2及び図1に示す。
各液体口腔用組成物にHAPペレット(ヒドロキシアパタイトペレット)を3分ずつ5回浸漬した後、HAPペレットを水で洗浄し、乾燥させた。次いで、HAPペレットを1N塩酸で1分間処理して吸着したフッ素を抽出し、フッ素イオン電極(ionplus-Fluoride(ORION社製))を用い、イオンアナライザー(Expandable ionAnalyzer EA940(ORION社製))により定量した。これを5回繰り返し、定量した値の平均を求め、フッ素吸着量の評価の指標とした。表2には、さらに比較例4のフッ素吸着量を100%としたときのフッ素吸着量の増加率(%)を示す。
表3に示す処方にしたがって、歯の着色汚れ付着抑制効果を評価するための液体口腔用組成物を調製した。次いで、下記方法にしたがって、紅茶による着色汚れの付着抑制効果を評価した。
結果を表3に示す。
試験に用いるHAPペレットを研磨紙(#1200)により研磨した後、超音波洗浄を1分間行った。次いで、得られたHAPペレットを各試験液に3分間浸漬した後、水で30秒間洗浄し、牛血清アルブミン1%溶液、及び紅茶溶液の順に3分間ずつ浸漬して、乾燥させた。これを10回繰り返した後、分光測色計(CM-700d、コニカミノルタ社製)を用いて、着色の程度をL*a*b表色系(マルセル表色)で表した際におけるb*値を測定し、浸漬する前との差Δb*値を求めた。
なお、比較例6として、試験液に浸漬する代わりに水に3分間浸漬したHAPペレットについても、同様にしてb*値を測定し、Δb*を求めた。Δb*が小さいほど、すなわちΔb*の絶対値が大きいほど有効に着色汚れの付着を抑制し、歯の美白を保持していることを意味する。
結果を表3及び図2に示す。表3には、Δb*の絶対値を示し、水である比較例6に対する着色抑制率(%)もあわせて示す。
表4に示す処方にしたがって、各歯磨組成物を調製した。次いで、下記方法にしたがって、きしみ感及び収斂感を評価した。
被験者3名(男性2名、女性1名)が、歯ブラシに歯磨き組成物1gをとり、約2分間自由にブラッシングした。口をすすいだ後のきしみ感及び収斂感について下記基準にしたがって評価を行った。被験者の協議による結果を表4に示す。
<きしみ感>
1:きしみを感じない
2:きしみをやや感じる
3:きしみを感じる
4:きしみを非常に感じる
<収斂感>
1:収斂感がない
2:収斂感がややある
3:収斂感がある
4:収斂感が非常にある
結果を表4に示す。
表5に示す処方にしたがって、各歯磨組成物を調製した。次いで、上記方法と同様にして、被験者3名によるきしみ感及び収斂感の評価を行った。
さらに、下記の方法にしたがって、ヒト歯への光沢付与効果の評価を行い、ヒト歯の表面をSEMで観察を行った。また、増粘性シリカと研磨性シリカを精製水におきかえた組成を調製し、実施例5、6の液体口腔用組成物と同様にして《着色汚れ付着抑制効果の評価》を行った。さらに、下記方法にしたがって、光沢付与効果及び美白効果の評価を行った。
結果を表5に示す。
(抜去歯の処理方法)
光沢付与効果及び後述する美白効果は、ヒト歯の抜去歯を用いて試験を行った。表5に示す各歯磨組成物に精製水を添加して30質量%濃度の歯磨組成物水溶液とし、各歯磨組成物水溶液にヒト歯を25℃の室内で24時間浸漬した。その後、イオン交換水で洗浄し、下記の方法により輝度を測定した。なお、歯磨組成物を30質量%濃度の水溶液としているのは、歯磨き行為により口腔内で唾液により希釈されるため、希釈時を想定して試験を行うためである。
輝度の測定には、偏光を利用した画像解析から表面反射光強度を測定する方法を用いた。評価用画像を撮影する装置として、カメラはデジタル一眼レフカメラNikon D70、レンズはAi AFマイクロ・ニッコール105mm F2.8D、ストロボ発光はワイヤレス・リモート・スピードライトSB-R200(いずれもニコン製)を組合せて設置したものを用いた。スピードライトの発光部及びレンズの前にプラスチック偏光板(エドモンド製)を透過軸が30度交差するように配置して撮影した。撮影画像はAdobe Photoshop CS3(アドビシステム製)を用いてハイライト部分の平均輝度を求めた。輝度は数値が大きいほど光沢が高いことを意味する。そして、上記抜去歯の処理前に測定したヒト歯の輝度と、歯磨組成物による処理後のヒト歯の輝度を測定し、(処理後の輝度-処理前の輝度)をΔ輝度として算出し、Δ輝度の値によって評価した。Δ輝度の数値が大きいほど光沢が増したことを意味する。
上記光沢付与効果の評価と同様にして、上記抜去歯の処理方法を用い、抜去歯の処理前と処理後のヒト歯(処理後のヒト歯:30質量%濃度の歯磨組成物の水溶液に24時間浸漬し、イオン交換水で洗浄した後のヒト歯)について、処理前と処理後の色差(Δb)を測定した。歯(抜去歯)の色(白さ)は、デジタルカメラD1x(ニコン製)と白色フラッシュ光源(コニカミノルタ製)を用いて撮影された画像をAdobe Photoshop(アドビシステムズ製)を用いてL*a*b*表色系で表し、b*の値によって評価した。Δb*は、歯磨組成物の水溶液による処理前と処理後のb*の差{(処理後のb*)-(処理前のb*)}を意味する。b*の値は0に近いほど、黄色味が少なく白さが増すことを意味し、Δb*が小さいほど、即ちΔb*の絶対値が大きいほど白さが増すことを意味する。
これに対して実施例は、きしみ感、収斂感が抑制されており、かつ汚れ付着抑制効果、成分(B)のフッ素吸着性能に優れ、しかも光沢付与効果、美白効果に優れる結果が得られた。これらの結果から、実施例は、成分(B)を含有し、歯へのフッ素吸着効果をもちながら、成分(A)による着色汚れ付着抑制効果、歯への光沢付与効果、美白効果が得られることがわかる。
