实验过程

A gel vehicle containing about 25-28% water (apart from water provided as humectant solvent), about 10-12% of 99.5% glycerine solution and about 30-35% of 70% sorbitol solution can readily provide a refractive index of about 1.43 to 1.46 and permit formation of a clear gel dentifrice in which the refractive index of the polishing agent is about 1.41 to 1.47 and within 0.02 of the refractive index of the liquid vehicle.
