Description
一方、エリスリトールはバイオフィルム除去効果が知られているが、さらにその効果を高めることが求められている。
そこで、本発明の課題は、エリスリトールを含有し、さらに既に形成されているバイオフィルム除去効果を向上させる歯磨組成物を得ることにある。
(A)エリスリトール 10〜65質量%、
(B)N−アシル酸性アミノ酸又はその塩 0.05〜0.55質量%、
(C)水 10〜25質量%
を含有し、成分(A)と成分(B)との質量比(A/B)が20〜400であって、塩化ナトリウムが実質的に配合されていない歯磨組成物を提供するものである。
(A)エリスリトールの含有量は、バイオフィルム除去効果を得る点、及び清涼感を得る点から、歯磨組成物中10〜55質量%がより好ましく、さらに10〜50質量%が好ましい。
篩:JIS標準篩 φ75mm
目開き:上段より、それぞれ500μm、355μm、250μm、180μm、125μm、90μm及び45μmの目開きを有する篩の下に受器を有する。
振盪機:ミクロ型電磁振動機M−2型(筒井理化学器機(株))
方法:試料15gを500μm篩上に載せ、電磁振動機にて5分間分級する。篩下率(積算量)を正規確立紙にプロットし、50%に対応する値を平均粒子径とする。
このような粒子径は、結晶状のエリスリトールを粉砕して調整することができる。エリスリトールの粉砕には、ローラミル、ハンマーミル、高速度粉砕機、パルベライザーなどを使用することができる。結晶状のエリスリトールは、市販品としては、日研化成(株)、三菱化学フーズ(株)、カーギル社等のものが入手可能である。
S.mutans ATCC25175株、A.viscosus ATCC43146株、S.gordonii ATCC10558株の各々の細菌をSCD培地(Soybean−Casein DigestBroth、日本製薬株式会社製)に0.5% Yeast Extract(Difco社製)を添加した培養液(SCD−YE培地)50mLに1白金耳を接種し、温度37℃、嫌気的条件(N280%、CO220%)で対数増殖期まで培養した。
口腔疾患の無い健常な男性より、パラフィンワックスを咀嚼させて分泌された唾液を採取し、遠心分離によって、唾液採取時に剥離した口腔内粘膜等を除去し、これをglass base dish(IWAKI φ27mm)に2mL/dishの割合で分注し、4℃で一昼夜静置することで glass base dishにヒトの唾液を吸着させた。
上記培養した細菌(S.mutans、A.viscosus、S.Gordonii)を分光光度計(BioSpec−mini 島津製作所製)により10mmの光路長で600nmのO.D.が0.7になるように培養液(SCD−YE培地)で調整し、各々の細菌を1mLを接種し、培養液50mLと混合した細菌混合液を2mL/dishの割合で唾液を付着させたglass base dishに添加し、24時間培養してバイオフィルムを形成させた。ここで、培養液は酵母0.5%(Yeast Extract、Difco社製)、Glucose 1.0%、Sucrose 2.0%を添加したものを用いた。
(1)で作成したバイオフィルムに対して、表1に記載の組成物(試験例1〜5、比較例1〜10)を1mL滴下し、室温(20℃)で30秒間の超音波処理をした。除去試験の超音波処理はヒトの含嗽に類似したレベルにするため超音波周波数が42KHzで設計されている超音波洗浄機AW5800(シチズン製)により行った。処理後、剥がれたバイオフィルム量(A)と、残ったバイオフィルム量(B)をフェノール硫酸法によって測定した。残ったバイオフィルムは、2N水酸化ナトリウム1mLを添加することによってバイオフィルムを剥がし、さらに2N塩酸1mLを添加して中和して回収した。剥がれたバイオフィルムは1mLの組成物とともに1mLの精製水を加えて回収した。これらの回収したバイオフィルムの量をフェノール硫酸法によって測定した。フェノール硫酸法は、回収したバイオフィルム20μLを96wellマイクロプレートリーダーに分注し、さらに5%(W/V)フェノール水溶液20μLを加え、98%濃硫酸100μLを添加して混合し、マイクロプレートレコーダーで490nmの吸光度を測定した。検量線は、0.0078〜0.125%のグルコース液の吸光度を用い、バイオフィルムの量を定量した。バイオフィルム除去率は、バイオフィルム量(A)/(バイオフィルム量(A)+バイオフィルム量(B))として求めた。試験の結果を表1及び図1、2に示す。なお、表1記載の組成物は、平均粒子径200μmのエリスリトールを配合し、完全に溶解させてからバイオフィルム除去試験を行った。
表2に示す歯磨組成物を製造し、歯磨組成物を使用した場合の泡質、歯磨組成物の各成分を混合した際の脱泡性を評価した。なお、歯磨組成物のpHは6.5〜7.5に調整した。
泡質の評価は、歯磨組成物の3名の使用により評価を行い、比較例11を基準に、泡のきめの細かさが比較例11よりも細かい場合を1、同じ場合を0、粗い場合を−1とし、泡もちが比較例11よりも良い場合を1、同じ場合を0、悪い場合を−1とし、3名の協議により評価を決めた。歯磨組成物の使用は、歯ブラシ(ピュオーラ レギュラーサイズ(花王(株)))に1.5cmとり1分間歯磨きを行った。
脱泡性の評価は、表2の組成物を回転数8rpm、真空圧0.09mPa、10分間攪拌し、比重(比重1)を測定する。次に回転数8rpm、真空圧0.096mPa、15分間攪拌し比重(比重2)を測定し、比重2/比重1の比率によって脱泡性を評価し、比重が減少し比重の比率が0.98以下の場合は×、比重の比率が1.00〜0.98の場合は○とした。ここで、攪拌混合機は、DALTON(株)製の万能混合攪拌機NDM/NDMVを用いた。
