Abstract
Propellant free foamable aqueous dentifrice system which is capable of being delivered as a foam to a toothbrush and which is stable on the brush and when placed in the mouth and used for tooth cleaning, continues to generate more foam. The system is liquid and as such can not be used without being foamed because it is so thin that it falls beneath the bristles of the toothbrush.
