ABSTRACT:
Hemostatic compositions and dental etching compositions for oral use include methyl salicylate in order to mask or disguise their otherwise unpleasant taste. The methyl salicylate, hemostatic and/or dental etching agent are dispersed within an aqueous carrier, which may be liquid or viscous as desired. In order to increase the stickiness and the viscosity of the carrier, a higher molecular weight polyol and/or a finely divided inorganic filler may be included. Methyl salicylate is selected as the flavorant because it has been found to have enhanced stability in the presence of strongly acidic compositions compared to other flavorants known in the art. In addition, methyl salicylate does not leave behind an unpleasant after taste. For this reason, methyl salicylate is uniquely suited for masking or disguising the profoundly sour, bitter and rusty taste of hemostatic agents or the sour or bitter taste of dental etching agents.
