COLLOIDAL MICROCRYSTALLINE CELLULOSE TOOTHPASTE OF REDUCED STRINGINESS AND IMPROVED FLAVOR RELEASE

摘要

A toothpaste composition with enhanced flavor release and reduced stringiness is disclosed. The composition comprises an abrasive, a humectant, a binder, a co-binder, a surface active agent, and water; in which: the co-binder is colloidal microcrystalline cellulose co-processed with a surfactant; colloidal microcrystalline cellulose co-processed with a hydrocolloid; colloidal microcrystalline cellulose co-processed with a hydrocolloid and an attriting agent; a mixture of colloidal microcrystalline cellulose co-processed with a hydrocolloid and an attriting agent in which the microcrystalline cellulose to attriting agent ratio is about 85:15 to about 30:70 by weight and the mean particle size of the attriting agent is about 0.1 to about 8 microns; colloidal microcrystalline cellulose co-processed with a hydrocolloid and an inorganic salt, in which microcrystalline cellulose have an average particle size less than 10 microns, and when the hydrocolloid is carrageenan, at least about 50% of the particles have a particle size less than 3.5 microns, when the hydrocolloid is a hydrocolloid other than carrageenan, at least about 30% of the particles have a particle size less than 3.5 microns, and when the hydrocolloid is a combination of carrageenan and another colloid, at least about 20% of the particles have a particle size less than 3.5 microns; or a mixture thereof; with the proviso that when the abrasive is silica, the co-binder is not colloidal microcrystalline cellulose co-processed with one of xanthan, alginate, and a cellulose gum in the absence of a water soluble inorganic salt.
