Toothpastes which contain 10-60 wt. % of polishing agents, 2-20 wt. % of humectants, 0.5-5 wt. % of water-soluble consistency regulators and 0.05-0.5 wt. % of antimicrobial biguanides, as well as 1-5 wt. % of other additives from the group of surface-active substances, aromatic oils, and sweeteners, have a particularly high biguanide availability if the polishing agent consists mainly of calcium carbonate, the consistency regulators are non-ionic polysaccharide derivatives and the surface-active substances are cationic surfactants with a linear alkyl group containing 12-18 carbon atoms and one or two tertiary amino groups or quaternary ammonium groups. Optionally a non-ionogenic solubilizer for the aromatic oil may also be present in the toothpastes.
A toothpaste in the form of an aqueous dispersion containing 10.0 to 60.0% by weight of polishes, 2.0 to 20.0% by weight of humectants, 0.5 to 5.0% by weight of water-soluble viscosity regulators, 0.05 to 0.5% by weight of antimicrobial biguanides, and 1.0 to 5.0% by weight of other additives from the group of surfactants, flavoring oils, and sweeteners, wherein the improvement is that calcium carbonate is predominantly present as the polish, non-ionic polysaccharide derivatives are present as the viscosity regulators, and a cationic surfactant containing a linear C.sub.12 -alkyl group and one or two tertiary amino groups or quaternary ammonium groups is present as the surfactant, a nonionic solubilizer for the flavoring oil optionally being present.
