以下では、実施例で実施された測定方法を記載する。
非表面反応炭酸カルシウム粒子、例えば、重質炭酸カルシウムの粒度分布は、マイクロメリティックス社、米国からのセディグラフ5100を用いて測定した。方法および機器は当業者に知られており、一般に充填剤および顔料の粒径を決定するために使用される。測定は、0.1重量%のNa4P2O7を含む水溶液中で行った。試料を、高速攪拌機および超音速を用いて分散させた。分散した試料を測定するために、さらなる分散剤は添加しなかった。
比表面積は、30分間250℃で加熱することによる試料の調整後、窒素を使用してISO 9277に従ってBET法により測定する。測定の前に、試料をブフナー漏斗内でろ過し、脱イオン水ですすぎ、オーブン中で90から100℃で一晩乾燥させる。続いて、ドライケーキを乳鉢でよく粉砕し、得られた粉末を一定重量になるまで130℃で湿度秤に配置する。
調製したウシのエナメル質試料を、Sigma VP電界放射型走査電子顕微鏡(カール・ツァイスAG、ドイツ)および約50Paのチャンバー圧を有する可変圧力二次電子検出器(VPSE)によって調べた。
MCC:重質炭酸カルシウムおよびリン酸に基づく表面反応炭酸カルシウム(d50=6.54μm、d98=16.8μm、SSA=25.1m2/g)。重質炭酸カルシウムはフランスのオルゴンから得られたものであり(d50=3μm、d98=12μm)、オムヤAG、スイスから市販されている。
[実施例1]練り歯磨き組成物
以下の表1にまとめた成分および量を用いて以下の手順に従って練り歯磨き試料1から4を調製した。
次のようにウシのエナメル質試料を調製した。
