Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
116 words
An anhydrous dentifrice which contains about 10 to 90% by weight of a liquid vehicle including a hydroscopic humectant, about 0.1 to 10% by weight of a dipeptide sweetner selected from the group consisting of L-aspartyl-L-phenylalanine methyl sweetener ethyl esters and L-aspartyl-L-hexahydrophenylalanine methyl and ethyl esters in admixture with about 0.1 to 15% by weight of a non-toxic acid anhydride selected from the group consisting of acetic-, succinic-, adipic-, fumaric-, lactic-, malic-, folic-, ascorbic-, aspartic-, benzoic-, isovaleric-, phenoxyacetic-, citric-, tartaric-, orthophosphoric-, lauric- and stearic acids and compatible mixtures thereof whereby the acid pH integrity of said sweetener is maintained about 3 to 5 and excess-free water present is absorbed thereby providing the stability in said sweetener.
Claim 2
Dependent Claim
116 words
An anhydrous dentifrice which contains about 10 to 90% by weight of a liquid vehicle including a hydroscopic humectant, about 0.1 to 10% by weight of a dipeptide sweetner selected from the group consisting of L-aspartyl-L-phenylalanine methyl sweetener ethyl esters and L-aspartyl-L-hexahydrophenylalanine methyl and ethyl esters in admixture with about 0.1 to 15% by weight of a non-toxic acid anhydride selected from the group consisting of acetic-, succinic-, adipic-, fumaric-, lactic-, malic-, folic-, ascorbic-, aspartic-, benzoic-, isovaleric-, phenoxyacetic-, citric-, tartaric-, orthophosphoric-, lauric- and stearic acids and compatible mixtures thereof whereby the acid pH integrity of said sweetener is maintained about 3 to 5 and excess-free water present is absorbed thereby providing the stability in said sweetener.
Claim 3
Dependent Claim
15 words
A dentifrice according to claim 1 wherein the dipeptide sweetener is a L-aspartyl-L-phenylalanine methyl ester.
Claim 4
Dependent Claim
15 words
A dentifrice according to claim 1 which is a toothpaste and includes a polishing agent.
Claim 5
Dependent Claim
16 words
A dentifrice according to claim 3 which includes about 5 to 75% of said polishing agent.
Claim 6
Dependent Claim
116 words
A dentifrice according to claim 4 which also includes from 0.5 to 10% of a gelling agent and 0.5 to 5% of a synthetic organic detergent and in which the polishing agent is selected from the group consisting of sodium aluminum silicate, hydrated alumina, dicalcium phosphate, silica xerogel and calcium carbonate and mixture thereof, and a vehicle selected from the group consisting of mannitol, sorbitol, glycerine and mixtures thereof, the gelling agent is selected from the group consisting of sodium carboxymethyl cellulose, hydroxyethyl cellulose, polyvinyl alcohol, Irish moss and silica aerogel and mixtures thereof and the synthetic organic detergent selected from the group consisting of water-soluble higher fatty acid salts and synthetic anionic and nonionic detergents.
Claim 7
Dependent Claim
21 words
A dentifrice according to claim 5 which contains therein, apart from said sweetener, about 0.1 to 2% of a flavoring material.
Claim 8
Dependent Claim
16 words
A dentifrice according to claim 3 additionally containing 0.1 to 3.0% of a further sweetening agent.
Claim 9
Dependent Claim
23 words
A dentifrice according to claim 3 additionally containing 0.1 to 10% of a combination of flavoring oils and sweetening agents in said vehicle.
Claim 10
Dependent Claim
13 words
A dentifrice as defined in claim 3 wherein said polishing agent is water-insoluble.
Claim 11
Dependent Claim
16 words
A dentifrice as defined in claim 1 further containing an effective amount of an anti-bacterial agent.
Claim 12
Dependent Claim
20 words
A dentifrice as defined in claim 3 wherein said polishing agent is about 20-95 percent by weight of the vehicle.
Claim 13
Dependent Claim
12 words
A dentifrice as defined in claim 1 additionally containing a surface-active agent.
Claim 14
Dependent Claim
30 words
A dentifrice as defined in claim 12 wherein said surface-active agent is selected from the group consisting of water-soluble sulfates of compounds having long chain alkyl radicals and α-olefin sulfonates.
Claim 15
Dependent Claim
27 words
A dentifrice according to claim 11 in clear gel form, containing a polishing agent of approximately the same index of refraction as the balance of the dentifrice.
Claim 16
Dependent Claim
39 words
