ABSTRACT:
The invention relates to liquid dentifrices which contain particulate siliceous abrasive cleaning agents, stably suspended in a liquid medium with the aid of a polysaccharide gum as suspending agent. By using a particulate siliceous abrasive cleaning agent with a specific surface area of between 50 and 900 m.sup.2 /g, and using a liquid medium which is free from polyol-type humectants, liquid dentifrices are obtained with satisfactory rheological properties. Preferably the compositions have a compositional viscosity index of between 3 and 30, said index being defined as ##EQU1## wherein S=concentration in % of thickening silica, if present, in the liquid medium and P=concentration in % of polysaccharide gum in the liquid medium.
