一方、表4の結果からわかるように、本発明の必須要件のいずれかに欠ける歯磨剤組成物(比較例1~19)では、殺菌効果、歯肉炎予防効果、口臭予防効果、更に歯磨剤使用中及び使用後の異味のなさ、歯磨剤組成物の表面の滑らかさの全てを満足するものは見られなかった。この場合、アスコルビン酸リン酸エステル塩の代わりにアスコルビン酸ナトリウムを配合しても、アスコルビン酸ナトリウムは安定配合されず歯肉炎及び口臭予防効果に劣り(比較例1,2)、イソプロピルメチルフェノールの代わりに塩化セチルピリジニウムを配合しても殺菌力及び口臭予防効果に劣り(比較例4,5)、界面活性剤が不適切な場合も殺菌力及び口臭予防効果に劣っていた(比較例9~12)。また、D/A比が不適切な場合はアスコルビン酸リン酸エステル塩の保存安定性を改善できず、満足な歯肉炎及び口臭予防効果が得られず、また、初期pHが不適切でも満足な歯肉炎及び口臭予防効果が得られず、いずれの場合も本発明の目的は達成できなかった。
