Abstract
An oral hygiene composition containing eucalyptol and a zinc salt, wherein the harsh taste or burn sensation ordinarily imparted by the eucalyptol and the astringency ordinarily caused by the zinc salt are abated or eliminated by effective amounts in the composition of a taste receptor blocker, preferably in combination with a three component flavor system containing at least one spice, at least one sweetener and at least one fruity note. The taste receptor blocker is preferably a hydrogenated, ethoxylated glycerol ester which has the mouth feel characteristic of a fat but which has a much higher degree of solubility and hence improved clarity (ie., reduced cloudiness) for the composition.
Claims33
A composition comprising eucalyptol, an effective amount of a taste receptor blocker that is a hydrogenated ethoxylated glycerol ester which is effective to mask the burning sensation ordinarily imparted by the eucalyptol, and a flavor system which includes at least one spice note, at least one sweetener, and at least one fruity note.
An oral hygiene composition comprising eucalyptol, a zinc salt, an effective amount of a taste receptor blocker and an effective amount of a flavor system which includes at least one spice note selected from ginger, clove, anise, or mixtures thereof;
- at least one sweetener;
- and at least one fruity note, wherein the taste receptor blocker and flavor system are effective to mask the burning sensation of the eucalyptol and the astringency of the zinc.
An oral hygiene composition comprising
- (a) about 0.02 to about 0.1% by weight of thymol;
- (b) about 20 to about 55% by weight of a sugar alcohol;
- (c) about 0.01 to about 0.035% by weight of anethole;
- (d) about 0.04 to about 0.12% by weight of eucalyptol;
- (e) about 0.02 to about 0.07% by weight of menthol;
- (f) about 0.05 to about 0.25% by weight of benzoic acid;
- (g) about 0.02 to about 0.09% by weight of methyl salicylate;
- (h) about 5 to about 35% by weight of ethanol;
- (i) about 0.05 to about 2.0% by weight of zinc salt;
- (j) about 0.5 to about 5.0% by weight of a hydrogenated ethoxylated glycerol ester;
- and
- (k) about 0.05 to about 0.25% by weight of flavor system which includes at least one spice note, at least one sweetener and at least one fruity note,
- wherein the burning sensation of the eucalyptol and the astringency of the zinc are masked by the hydrogenated ethoxylated glycerol ester and wherein said percents by weight are based on the total weight of the composition.
A method for masking the burning sensation of eucalyptol in an oral hygiene composition comprising the step of adding to said composition an effective amount of a taste receptor blocker that is an ethoxylated glycerol ester having an ethoxylation number in the range of from 35 to 60 and a flavor system that includes at least one spice note, at least one sweetener, and at least one fruity note.
