PURPOSE:To obtain a composition, having a viscosity capable of retaining the shape when extruded from a housing container onto a toothbrush without permeating into the flocked part of the toothbrush and capable of reducing the viscosity and rapidly dispersing in the mouth when inserting a toothbrush into the mouth and brushing the teeth. CONSTITUTION:This dentifrice composition comprises a water-soluble polymer and has >=200,000mPa.s viscosity at 0.2sec<-1> shearing rate and a viscosity at 10.0sec<-1> of <=1/10 that at 0.2sec<-1> shearing rate. |
