Abstract
Provided is a pumping type toothpaste product including a toothpaste composition. The toothpaste composition includes a polishing agent, and thus prevents the piston of a pumping type container from being worn by the polishing agent contained in the toothpaste composition so that the contents of the container may be ejected out smoothly. Also provided is a gel-like toothpaste composition having excellent viscosity retentivity. Further, provided is an oral composition showing high elasticity even at low viscosity, undergoing little change in viscosity with time and having significantly improved shape retentivity, flowability and dispersion stability through the synergic effect of xanthan gum and a thickening polymer.
Claims7
A pump dispenser toothpaste product comprising:
- a pump container having a piston and
- a toothpaste composition for use with the pump container having a piston;
- wherein the toothpaste composition comprises sorbitol, a liquid polyol, and a precipitated silica as polishing agent;
- wherein the sorbitol is present in an amount of 0.001-20 wt % based on the total weight of the toothpaste composition,
- wherein liquid polyol comprises any one selected from the group consisting of polyethylene glycol (PEG) 200-600, glycerol, propylene glycol, ethylene glycol, polypropylene glycol and a mixture thereof,
- wherein the liquid polyol is present in an amount of 30-85 wt % based on the total weight of the toothpaste composition,
- wherein the precipitated silica is present in an amount of 1-20 wt % based on the total weight of the toothpaste composition,
- wherein the mole number of the hydroxyl or ether groups of the liquid polyol forming hydrogen bonding with the hydroxyl groups of the sorbitol is at least 0.2 times of the hydroxyl groups of the sorbitol,
- wherein the pump container having piston comprise a dip pump, and
- wherein the toothpaste composition has a change in viscosity of 100 to 15,000 cP after least 2 years as compared to the viscosity of the composition upon its preparation, when viscosity measurement is carried out under conditions of 25° C., 20 rpm and 5 cycle by using BrookField, RVT spindle No. 7.
