A non-aqueous paste or gel dentifrice composition comprising a water soluble, non-aqueous vehicle having dispersed therein an orally acceptable organic or inorganic peroxide and a bicarbonate salt. The quantities and relative proportions of the peroxide and bicarbonate are sufficient to provide quantities of bactericidally active oxygen upon breakdown of said peroxide by tissue contact and/or by reaction with said bicarbonate in the oral cavity. The bicarbonate also provides a neutral or basic pH upon dissolution of the composition in water. The peroxide and/or bicarbonate is provided with a water soluble barrier coating which is insoluble in the vehicle, to prevent reaction therebetween in the absence of water dissolution of the coating. Normal dentifrice adjuvants may also be present, which can similarly be provided with a water soluble barrier coating.

A non-aqueous paste or gel dentifrice composition, comprising: a water soluble, non-aqueous vehicle selected from the group consisting of polyalkylene glycols, polyoxyalkylene derivatives of ethylene diamine, polyoxyethylene fatty acid esters, non-ionic surfactants, anionic surfactants, ampholytic surfactants, cationic surfactants, alkanolamides, thickened glycerol, propylene glycol or sorbitol, and mixtures thereof, having dispersed therein (a) an orally acceptable organic or inorganic peroxide; and (b) a bicarbonate salt; said composition being substantially completely anhydrous; the quantities and relative proportions of said peroxide and bicarbonate being sufficient to provide quantities of bactericidally active oxygen upon breakdown of said peroxide by tissue contact and/or by reaction with said bicarbonate in the oral cavity; the amount of said bicarbonate being effective to provide a neutral or basic pH upon dissolution of said composition in water; and at least one of said peroxide or bicarbonate being provided with a water-soluble barrier coating which is insoluble in said vehicle selected from the group consisting of guar gum, xanthate gum, gum arabic, gum tragacanth, locust bean gum, carob bean gum, gelatin, pectin, cellulosic polymers, polyethylene glycols, a water soluble starch, and mixtures thereof, to prevent reaction therebetween in the absence of water dissolution of said coating; whereby upon said composition being contacted with substantial quantities of water, including in the oral cavity of a user of said composition, dissolution of the said barrier coating enables reaction of said peroxide and bicarbonate to augment release of said active oxygen, to inhibit the motility of oral bacteria in said cavity, and dissolution of said bicarbonate enables neutralizing of acid secretions in the said oral cavity.
