Abstract
Description
以下の定義は、本願内で使用される用語をより明確に定義するために提供される。特段記載されない限り、以下の定義はこの開示に該当する。この開示内で用語が使用されるが特段定義されていない場合、その定義が本願内で適用される他の開示または定義と矛盾するかまたはその定義が適用される任意の請求項を不定または非許容にしない限り、IUPAC Compendium of Chemical Terminology,第2版(1997)からの定義を適用できる。本願内に参照をもって包含されるあらゆる文献によって提供される定義または使用法が本願内で提供される定義または使用法と矛盾する範囲では、本願内で提供される定義または使用法が支配的である。
本願内で開示されるのは一般に、(i)約6μm以上のd50メジアン粒径、(ii)約1.1〜約2.4の範囲の(d90−d10)/d50比、(iii)20質量%の添加量で約40〜約200の範囲のRDA、および(iv)約0.9以上の球形度係数(S80)を特徴とすることができる球状シリカ粒子である。それらの球状シリカ粒子の製造方法および前記球状粒子を含有する歯磨剤組成物も本願内で開示され且つ説明される。
本発明の態様と一致する、改善されたRDA性能を有する球状シリカ粒子は以下の特徴を有することができる: (i)約6μm以上のd50メジアン粒径、(ii)約1.1〜約2.4の範囲の(d90−d10)/d50比、(iii)20質量%の添加量で約40〜約200の範囲のRDA、および(iv)約0.9以上の球形度係数(S80)。さらなる態様において、本発明と一致するシリカ粒子は、以下に記載される任意の特徴または特性、およびその任意の組み合わせを有し得る。
本願内に開示される球状シリカ粒子は、特定の合成手順に限定されない。しかしながら、所望の球形度を達成するために、連続ループ反応器プロセスを使用して球状シリカ粒子を形成できる。一般的な方法および関連する反応器系(1つまたはそれより多くのループ反応器パイプの連続ループを含み得る)は、米国特許第8945517号明細書および第8609068号明細書内に記載されており、これらはその全文が参照をもって本願内に含まれる。粒子の球形度を改善するため、一般的な方法および反応器系に、本願内に記載される適切な修正がなされる。
球状シリカ粒子を、任意の適した組成物中で、任意の適した最終用途のために使用できる。多くの場合、シリカ粒子を口腔ケア用途、例えば歯磨剤組成物中で使用できる。歯磨剤組成物は、任意の適した量のシリカ粒子、例えば約0.5〜約50質量%、特定の態様において約1〜約50質量%、特定の態様において約5〜約35質量%、特定の態様において約10〜約40質量%、およびより特定の態様において約10〜約30質量%の球状シリカ粒子を含有できる。それらの質量パーセントは、歯磨剤組成物の総質量に基づく。
不規則シリカ粒子
表Iに、不規則且つ非球状の粒子の形態を有する比較用シリカ材料1Aおよび2Aの特定の特性を要約する。図1(例1A)および図2(例2A)は、例1Aおよび2Aの不規則且つ非球状の粒子を実証するSEM像である。例1Aおよび2Aは、Huber Engineered Materialsから市販されている従来のシリカ材料であった。
球状シリカ粒子
例3A〜8Aについて、連続ループ反応器プロセス(例えば米国特許第8945517号明細書および第8609068号明細書参照)を使用して、球状の形態およびより狭い粒径分布を有するシリカ粒子を製造した(例えば最終シリカ生成物中でより少ない325メッシュの残留分)。
例3Cおよび7C
練り歯磨き配合物、およびPCRおよびRDA試験
シリカの試料1A〜8Aを、表IIに要約するとおり、練り歯磨き配合物1B〜8B中でそれぞれのシリカを20質量%の添加量で、練り歯磨き配合物3Cおよび7C中ではそれぞれのシリカを10質量%の添加量で使用した。
不規則シリカ粒子
表IVに、不規則且つ非球形の粒子の形態を有する比較用シリカ材料9A〜13Aの特定の特性を要約する。例9AはHuber Engineered Materialsから市販されている従来のシリカ材料であり、且つ例10A〜13Aは、例9Aの未粉砕の試料を、d50粒径3.5μm(例10A)、6.2μm(例11A)、9.4μm(例12A、広い粒径分布)および9.3μm(例13A、狭い粒径分布)まで空気ミリングすることにより製造された。
練り歯磨き配合物、およびPCRおよびRDA試験
シリカ9A〜13Aの試料を、表Vに要約されるとおり、練り歯磨き配合物9B〜13B中にそれぞれのシリカを20質量%の添加量で使用した。
表IIIのデータと表VIのデータとを比較すると、球状シリカ材料の挙動は基本的に(且つ意外にも)、非球状且つ不規則な形状の従来の歯科用シリカの挙動とは異なる。粒径および粒径分布を使用して、高度に球状の材料を有するRDAおよびPCRを制御できる一方で、従来の不規則に成形されたシリカについては、粒径および粒径分布は著しい影響を有さない。

(a) 鉱酸およびアルカリ金属ケイ酸塩を、液体媒体の流れを含むループ反応領域に連続的に供給し、そこで少なくとも一部の鉱酸およびアルカリ金属ケイ酸塩が反応してループ反応領域の液体媒体中でシリカ粒子を形成すること、
(b) 液体媒体をループ反応領域を通じて連続的に再循環させ、そこでループ反応領域はステータースクリーンを含まない、もしくはループ反応領域は断面積で3mm2より大きい開口部を有するステータースクリーンを含むか、またはループ反応領域中の剪断頻度は1000000未満の相互作用数/分である、またはそれらの両方であること、且つ、
