Description
また、本発明は、上記造粒物を含有する口腔用組成物を提供するものである。
また、本発明は、亜鉛化合物含有造粒物を含有する口腔用組成物であって、前記造粒物に含まれる亜鉛化合物が亜鉛濃度として口腔用組成物中0.01〜1質量%である口腔用組成物を提供するものである。
水不溶性粉末材料の造粒物中の濃度は、60〜99質量%が好ましく、より好ましくは70〜98質量%、さらにより好ましくは80〜96質量%である。
結合剤の含有量は、造粒物中0〜30質量%が好ましく、1〜20質量%がさらに好ましい。
なお、平均粒子径は以下のように測定される。
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。
また、かかる亜鉛化合物含有造粒物に含まれる亜鉛化合物の濃度は、歯垢形成抑制効果及び組成物の味の点から、亜鉛濃度として口腔用組成物中0.01〜1質量%が好ましく、さらに0.03〜0.5質量%、特に0.06〜0.25質量%が好ましい。
亜鉛化合物含有造粒物は炭酸カルシウム(平均一次粒子径:0.05μm)と酸化亜鉛を混合し、転動造粒機により製造した。両原料を装置内(機器:ニューグラマシン SEG850型)で混合し、造粒時に粉体に対して15%の精製水を加え造粒を行った。造粒工程終了後、乾燥機内(機器:ロータリーキルン)で20〜30分程度乾燥させ、表1記載の亜鉛化合物含有造粒物を製造した。平均粒子径付近の造粒物をとりだし、微小圧縮試験機(島津製作所製、MCTM−500)で造粒物強度を測定したところ、いずれも10〜20g/個であった。なお、造粒物は電動篩機により粒子径50μm以下の造粒物を除去した。
表1記載の処方に従って実施例1〜3、比較例1〜2の歯磨剤を調製した。香味評価は歯磨剤使用直後に行った。
○:亜鉛由来のえぐ味を感じない、あるいはやや感じるが商品として問題はない。
×:亜鉛由来のえぐ味を強く感じる。
健康な20〜30代の男性9名を被験者として以下の手順に従って評価を行った。
なお、順序効果が出ないようにサンプルはランダムクロスオーバー法を用い、術者、被験者ともに評価サンプルの中身を知らないダブルブラインドで評価した。
24時間ブラッシング停止した後、歯科衛生士により歯垢を赤染め(染色液:プロスペック)して、写真撮影と歯垢の量を測定した*(測定部位 上顎全顎 下顎左右4−7の頬側)。
*測定方法:1歯を5分割し各分割面の歯垢の高さ(歯周ポケットプローブを用いて0.5mm単位の高さ)を求める。
歯ブラシのみでブラッシングした場合の歯垢形成量を基準として実施例2及び比較例1の歯垢形成抑制率を図1に示した。実施例2の歯磨剤は、比較例1の歯磨剤に比べて顕著に高い歯垢形成抑制効果を示した。
・評価品使用による歯垢形成量:ハミガキ剤1gをハブラシ(チェックスタンダード)に付け、同一の歯科衛生士により2分間ブラッシングした際の歯垢形成量
Claims (5)
- 水への溶解度が2mg/100mL(15℃)以下である酸化亜鉛を亜鉛濃度として1〜30質量%含有し、平均粒子径が100〜500μmであり、かつ崩壊硬度が10〜50g/個である、口腔用組成物に適用するための造粒物。
