Dentifrices.

摘要

A dentifrice composition containing an anticaries agent and an abrasive is produced to which has been added at least one colour indicator which, when the user brushes his or her teeth with the dentifrice, results in a colour change in the dentifrice within the user's mouth after a predetermined period of brushing time has elapsed for the purpose of indicating to the user that he or she has brushed his or her teeth a sufficient length of time.
