Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
56 words
A substantially non-toxic composition for controlling plaque comprising as an active ingredient an amount of a synergistic mixture of tetradecylamine and a metal wherein said metal is zinc or aluminum or both in admixture with an acceptable oral medium compatible with said mixture, said amount being effective to control said plaque at the site of formation.
Claim 2
Dependent Claim
56 words
A substantially non-toxic composition for controlling plaque comprising as an active ingredient an amount of a synergistic mixture of tetradecylamine and a metal wherein said metal is zinc or aluminum or both in admixture with an acceptable oral medium compatible with said mixture, said amount being effective to control said plaque at the site of formation.
Claim 3
Dependent Claim
29 words
A composition as defined in claim 1 wherein the amount of said metal is at least about 0.001 molar and of said tetradecylamine is at least about 0.005 molar.
