<p><P>PROBLEM TO BE SOLVED: To provide a dentifrice composition which has moderate polishing ability, high cleaning ability, reduced bitter taste, and good feel of use. <P>SOLUTION: The dentifrice composition includes (A) a synthesized amorphous aluminum-bonded silicate in which the amount of aluminum is in the range of 0.5-7.5 mass% to SiO<SB>2</SB>as Al<SB>2</SB>O<SB>3</SB>and the amount of OH groups is 2.0-3.5 mass% to SiO<SB>2</SB>and (B) l-menthol. The dentifrice composition barely has injurious property to the teeth, moderate polishing ability and high cleaning ability without damaging the teeth, reduced bitter taste associated with the synthesized amorphous aluminum-bonded silicate of a silica dentifrice, and good feel of use. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
