調製した歯磨剤組成物を歯磨用チューブ容器に充填し、直後の組成物中の非イオン性抗菌剤定量値(質量%)を初期値とし、60℃で1ヶ月保存した後の組成物中に含まれる非イオン性抗菌剤の配合濃度を評価サンプル値(質量%)とし、下記式(1)により残存率を計算し、90%以上の残存率を示すものを安定性に優れるものと判断した。なお、非イオン性抗菌剤の定量は歯磨製剤を10g分取し(チューブから押し出した最初の10gを使用)、60%エタノール溶液で抽出した後、液体クロマトグラフィーで行った。測定条件は、カラム温度45℃、アセトニトリル/水/酢酸混液(60:40:1)を移動相に用い、1.0mL/分の流量で、紫外吸光光度(測定波長280nm)での絶対検量線法により測定した(表1~5)。

(1)モデル歯周病原性バイオフィルムの作製方法
直径7mm×厚さ3.5mmのハイドロキシアパタイト(HA)板(HOYA株式会社製)を0.45μmのフィルターでろ過したヒト無刺激唾液に4時間浸漬処理したものをモデルバイオフィルム作製の担体(モデルバイオフィルム作製用HA担体)に用い、培養液は、ベイサルメディウムムチン培養液(BMM)*1を用いた。モデルバイオフィルムを作製するために使用した菌株はAmerican Type Culture Collectionより購入したアクチノマイセス ヴィスコサス(Actinomyces viscosus)ATCC43146、ベイヨネラ パルビュラ(Veillonella parvula)ATCC17745、フゾバクテリウム ヌクレアタム(Fusobacterium nucleatum)ATCC10953、ポルフィロモナス ジンジバリス(Porphyromonas gingivalis)ATCC33277を用いた。前記4菌種を、予めBMM3,000mLを入れたRotating Disk Reactor(培養槽)にそれぞれ1×107cfu/mL(cfu:colony forming units)になるように接種した。前記モデルバイオフィルム作製用HA担体を菌摂取BMM培養液に浸漬し、37℃、嫌気条件下(5%炭酸ガス、95%窒素)で24時間培養した。その後、同条件下、BMM培養液を置換率5vol%/時間の割合で連続的に供給して10日間培養を行い、HA表面に4菌種混合のモデルバイオフィルムを形成させた。
