Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
84 words
A dentifrice comprising about 0.01-5% by weight of a water-soluble non-toxic amino-cyano polymeric diguanide as antibacterial agent wherein said antibacterial agent is a mixture of the monofluorophosphate salt of an amino-cyano polymeric diguanide having the formula: ##EQU1## wherein Y is selected from the group consisting of NH.sub.2 (CH.sub.2).sub.6 -- and ##EQU2## X is selected from the group consisting of --NH 2 and ##EQU3## and n is an integer 2-6, and a dental vehicle for said agent compatible therewith, containing a solid water-insoluble polishing material.
Claim 2
Dependent Claim
84 words
A dentifrice comprising about 0.01-5% by weight of a water-soluble non-toxic amino-cyano polymeric diguanide as antibacterial agent wherein said antibacterial agent is a mixture of the monofluorophosphate salt of an amino-cyano polymeric diguanide having the formula: ##EQU1## wherein Y is selected from the group consisting of NH.sub.2 (CH.sub.2).sub.6 -- and ##EQU2## X is selected from the group consisting of --NH 2 and ##EQU3## and n is an integer 2-6, and a dental vehicle for said agent compatible therewith, containing a solid water-insoluble polishing material.
Claim 3
Dependent Claim
84 words
A dentifrice comprising about 0.01-5% by weight of a water-soluble non-toxic amino-cyano polymeric diguanide as antibacterial agent wherein said antibacterial agent is a mixture of the carbonate salt of an amino-cyano polymeric diguanide having the formula: ##STR7## wherein Y is selected from the group consisting of NH.sub.2 (CH.sub.2).sub.6 -- and ##STR8## X is selected from the group consisting of --NH 2 and ##STR9## and n is an integer 2-6, and a dental vehicle for said agent compatible therewith, containing a solid water-insoluble polishing material.
Claim 4
Dependent Claim
84 words
A dentifrice comprising about 0.01-5% by weight of a water-soluble non-toxic amino-cyano polymeric diguanide as antibacterial agent wherein said antibacterial agent is a mixture of the carbonate salt of an amino-cyano polymeric diguanide having the formula: ##STR7## wherein Y is selected from the group consisting of NH.sub.2 (CH.sub.2).sub.6 -- and ##STR8## X is selected from the group consisting of --NH 2 and ##STR9## and n is an integer 2-6, and a dental vehicle for said agent compatible therewith, containing a solid water-insoluble polishing material.
Claim 5
Dependent Claim
88 words
An oral preparation comprising about 0.01-5% by weight of a water-soluble non-toxic amino-cyano polymeric diguanide as antibacterial agent wherein said antibacterial agent is a mixture of the phosphate salt of an amino-cyano polymeric diguanide having the formula: ##STR10## wherein Y is selected from the group consisting of NH 2 (CH 2 ) 6 -- and ##STR11## X is selected from the group consisting of --NH 2 and ##STR12## and n is an integer 2-6, and a dental vehicle for said agent compatible therewith, containing a water-insoluble polishing material.
Claim 6
Dependent Claim
88 words
An oral preparation comprising about 0.01-5% by weight of a water-soluble non-toxic amino-cyano polymeric diguanide as antibacterial agent wherein said antibacterial agent is a mixture of the phosphate salt of an amino-cyano polymeric diguanide having the formula: ##STR10## wherein Y is selected from the group consisting of NH 2 (CH 2 ) 6 -- and ##STR11## X is selected from the group consisting of --NH 2 and ##STR12## and n is an integer 2-6, and a dental vehicle for said agent compatible therewith, containing a water-insoluble polishing material.
Claim 7
Dependent Claim
17 words
