Abstract

An antibacterial oral hygiene composition in aqueous form comprising: (a) from about 0.05% to about 0.2% by weight of sodium benzoate; (b) from about 0.01% to about 1.0% by weight of a weak carboxylic acid; (c) from about 2.0% to about 5.0% by weight of a buffering agent capable of buffering the composition to a pH of about 3.0 to about 8.0; (d) from 0% to about 1.5% by weight of a surfactant; (e) from 0% to about 0.2% by weight of sodium saccharin, or an amount sufficient to provide a sweetening effect equivalent thereto of a sweetening agent; (f) from 0% to about 2.0% by weight of a flavoring agent; and (g) sufficient water to total 100%.

Claims22

Dependent claims

An oral hygiene antibacterial mouthwash composition that is

a) water clear,
b) physiologically acceptable,
c) non-alcoholic,
d) free from disagreeable tasting antibacterial agents,
e) safe and organoleptically tolerable in the oral cavity and has no significant side effects either orally or systemically, and
f) controls malodor in the mouth when it contacts the tissue of the oral cavity or teeth for a sufficient time to reduce the malodor;
which comprises (I)
an effective antibacterial combination consisting essentially of:
(Ia) from about 0.05% to about 0.2% by weight, based on the total weight of the composition, of sodium benzoate;
(Ib) from about 0.01% to about 1.0% by weight, based on the total weight of the composition, of a weak carboxylic acid selected from the group consisting of citric acid, tartaric acid, and benzoic acid;
in which the proportion of (a) to (b) synergistically inhibits oral microorganisms on contact of the antibacterial mouthwash composition with the tissue of the oral cavity or teeth,
and (II)
(IIa) from about 2.0% to about 5.0% by weight, based on the total weight of the composition, of a buffering agent;
(IIb) about 0.25% to about 1.5% by weight, based on the total weight of the composition, of a surfactant;
(IIc) about 0.05% to about 0.2% by weight, based on the total weight of the composition, of sodium saccharin, or an amount sufficient of a sweetening agent to provide a sweetening effect equivalent thereto;
(IId) about 0.05% to about 2.0% by weight, based on the total weight of the composition, of a flavoring agent selected from the group consisting of the cinnamon, cassia, anise, and mint;
and
(IIe) sufficient water to total 100%, the composition having a pH of from about 3.0 to about 8.0.
