A61K 716

US Classification:

424 53, 424 49

Abstract:

Stable topical oral compositions comprising at least a minimally effective amount of chlorite ion are disclosed, wherein the pH of the final composition is greater than 7, the composition is essentially free of chlorine dioxide, and the composition is stable against loss of chlorite for a period of at least one year under normal storage conditions at about 25Â C. or for a period of 3 months under accelerated storage conditions at about 40Â C. Preferably the compositions further comprise a flavor system, which is stable against degradation by chlorite. The compositions are formulated as therapeutic rinses, especially mouth rinses, as well as toothpastes, gels, tooth powders, chewing gums, mouth sprays, lozenges (including breath mints), dental implements (such as dental floss and tape), and pet care products.

International Classification:

A61K007/16

US Classification:

424/049000

Abstract:

The present invention relates to methods and an oral care composition for topical, oral administration in a human or other animal comprising: a. from about 1% to about 40%, by weight of the composition, of a retentive agent selected from the group consisting of water soluble hydrophilic gums, water soluble hydrophilic polymers, and mixtures thereof, the retentive agent having the property of hydrating upon exposure to water or saliva resulting in the composition forming an intact hydrated mass to provide a Retention Index of about 1 to about 4; and b. a safe and effective amount of a topical, oral care carrier; wherein the composition is a non-cariogenic, chewable solid unit dosage form; and the composition comprises less than about 65% by weight of water insoluble particulates. The present invention further relates to an oral care dentifrice composition comprising: a. from about 30% to about 65%, by weight of the composition, of a water insoluble, particulate retentive agent having a water solubility of less than about 1 g/30 g at 25 C.; b. a safe and effective amount of an oral care active; c. a safe and effective amount of a surfactant; d. a safe and effective amount of a buffer; wherein the composition is a chewable dentifrice solid unit dosage form, is non-effervescent, non-cariogenic; and wherein the composition has a Retention Index of from about 1 to about 4.
