J 7026 (R) ABSTRACT The present invention relates to liquid dentifrices which contain particulate abrasive material, stably suspended in an aqueous vehicle with the aid of a polysaccharide gum as suspending agent. It has been found that high levels of the particulate abrasive material can be stably suspended with less polysaccharide gum than in the prior art, if a small amount of an alkalimetal bicarbonate is included in the dentifrices. This also significantly reduces the loss of available F- in the dentifrice if a fluorine-containing anticaries agent such as sodium monofluorophosphate is included.
