Abstract
Abstract Oral products containing bis-biguanido hexanes are disclosed which are effective in preventing the accumulation of bacterial plaque and do not stain teeth. Incorporation of certain reducing agents has been found to prevent dental staining while maintaining the activity of bis-biguanido hexanes in oral products. Effective reducing agents include, hydrogenated coumarin, and tri-hydroxylated benzoic acid and its lower alkyl (C1-C4) esters.
