Abstract
Abstract The invention provides plaque-inhibitory agents useful in oral compositions such as mouthwashes, toothpastes, mouthrinses, dental creams, toothpowders etc. comprising polysaccharides such as xanthan gum, gum tragacanth (pectin), guar gum, gum karaya, chondroitin sulfate, polygalacturonic acid, sodium alginate and carrageenans of the kappa/lambda configuration. The agents are effective in plaque-inhibiting at concentrations between about 0.0025% and 2.000% on a weight/volume basis.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
67 words

Claim 2
Dependent Claim
67 words
An oral aqueous or aqueous/alcoholic-based anti-plaque mouthwash, mouthspray, or mouthrinse composition for inhibiting plaque comprising an antiplaque agent, said antiplaque agent consisting essentially of an effective amount of from at least about .0025% w/v. to not more than about 4% w/v a polysaccharide selected from the group consisting of xanthan gum, gum tragacanth, guar gum, gum karaya, chondroitin sulfate, polygalacturonic acid, and carrageenans of the kappa/lambda configuration.
