Preparation of a visually clear gel dentifrice comprising a precipitated silica polishing agent having a refractive index of about 1.44, a water-swellable synthetic anionic polycarboxylate polymer which is added in solid form and a liquid vehicle comprising water and sorbitol wherein (a) when the total water content is above 30% to about 33% by weight of said dentifrice, sorbitol on a neat basis is present in amount of above 30% to about 36% by weight of said dentifrice (b) when the total water content is about 27% up to below 30% by weight of said dentifrice, sorbitol on a neat basis is present in amount of about 20% up to below 30% by weight of said dentifrice and other humectant if present, is in neat amount of up to 15% by weight of said dentifrice and also adding to said liquid vehicle about 1-4% by weight of dentifrice of solid water-swellable synthetic anionic polycarboxylate polymer. |
