"The use of a su00eclica precipitation process to thicken compositions dentifru00eccias or provide texture to dentifru00eccias compositions and compositions dentifru00eccias".Use as thickening agent or texturing in the compositions dentifru00edcias, a highly dispersible precipitated silica which has a pH of 3.5 to 9; an oil absorption of more than 200 ml / g; and a specific surface area CTAB from 70 to 250 m ^ 2 ^ / g; a median diameter of at least 20 109 m determined by laser diffraction without ultrasound.The rate of residual anion, expressed as sodium sulfate, less than 5% by weight.
