| 摘要 |
The invention relates to a dentifrice composition comprising: (i) 40 to 60 weight% Polyethyleneglycol or a derivative thereof; and, (ii) 0.01 to 2 weight% N-substituted p-menthane carboxamide. Preferred N-substituted p-menthane carboxamide is selected from N-(4- cyanomethylphenyl)p-menthanecarboxamide, N-(4-sulfamoylphenyl)p-menthanecarboxamide, N-(4-cyanophenyl)p-menthanecarboxamide, N-(4-acetylphenyl)p menthanecarboxamide, N-(4-hydroxymethylphenyl)p menthanecarboxamide, or N-(3-hydroxy-4-methoxyphenyl) p menthanecarboxamide. The invention is based on the finding that the bitter taste associated with dentifrice compositions which contain Polyethyleneglycol can be effectively masked when the dentifrice contains a N-substituted p-menthane Carboxamide. |
