Abstract
A transparent liquid dentifrice which comprises a particulate silica abrasive material present in from 10 to 15% by weight of the composition, stably suspended in an aqueous liquid vehicle with the aid of a suspending agent; and a humectant system which consists essentially of sorbitol, present in from 50 to 55% by weight of the composition (measured as the 100% active), and polyethylene glycol with average molecular weight in the range 200 to 600, present in from 0.5 to 3% by weight of the composition.
Claims16
A transparent liquid dentifrice which consists essentially of water as an aqueous liquid vehicle in from 15 to 40% by weight of the composition, a particulate silica abrasive material having an average particle size between 1 and 20 .mu.m present in from 10 to 15% by weight of the composition, stably suspended in the liquid vehicle with the aid of a suspending agent;
- and a humectant system which consists essentially of sorbitol, present in from 50 to 55% by weight of the composition (measured as the 100% active), and polyethylene glycol with average molecular weight in the range 200 to 600, present in from 0.5 to 3% by weight of the composition, wherein the overall viscosity of the dentifrice is sufficient to enable the dentifrice to be squeezed out of a dispenser as a continuous strand and not to sink into a toothbrush containing such strand, said dentifrice being free of thickening silicas or pyrogenic silicas.
