前記口臭抑制効果の評価方法に準じ、試験後として歯磨きして4時間経過後の口臭を採取して口臭強度を判定し、更に、同様にして口臭改善度を求め、口臭抑制効果を評価した。
被験者10名を用い、歯磨剤組成物約1gを歯ブラシにとり、3分間歯磨きを行った際の金属味について、金属味を全く感じないを4点、やや金属味を感じるを3点、金属味を感じるを2点、金属味を非常に感じるを1点として、判定した。
10名の平均点から以下の基準で、金属味の抑制効果を評価した。
金属味の抑制効果の評価基準:
◎:平均点が3.5点以上4.0点未満
○:平均点が3.0点以上3.5点未満
△:平均点が2.0点以上3.0点未満
×:平均点が1.0点以上2.0点未満
以下、処方例を表5に示す。処方例の歯磨剤組成物を上記と同様に調製し、同様に評価したところ、口臭抑制効果、歯磨剤のきめ、液分離のなさがいずれも◎であった。
