Abstract
Abstract A novel dry dentifrice powder composition, instantly transformable, into a smooth and homogeneous dental cream, when mixed with water, so that the user can prepare, instantaneously, his own dental cream. This is attained by incorporating an effective amount of one gum or mixture of several gums, to the conventional ingredients used in the dental powders.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
86 words
A method of instantly converting a dry powder dentifrice composition into a homogeneous dental cream comprising: (a) combining with components common to conventional dry dentifrice compositions, from 2% to 10% by weight, based on the weight of the dry powder dentifrice composition, of at least one readily water-soluble dry powdered gum and an amount of a magnesium or calcium silicate effective as a polishing agent, and (b) adding an amount of water sufficient to immediately convert the dry powder dentifrice composition into a homogeneous dental cream.
Claim 2
Independent Claim
86 words
A method of instantly converting a dry powder dentifrice composition into a homogeneous dental cream comprising: (a) combining with components common to conventional dry dentifrice compositions, from 2% to 10% by weight, based on the weight of the dry powder dentifrice composition, of at least one readily water-soluble dry powdered gum and an amount of a magnesium or calcium silicate effective as a polishing agent, and (b) adding an amount of water sufficient to immediately convert the dry powder dentifrice composition into a homogeneous dental cream.
Claim 3
Dependent Claim
80 words
The method of claim 1, wherein said at least one readily water-soluble gum is selected from the group consisting of arabic gum, tragacanth gum, karaya gum, larch gum, ghatty gum, naturally occurring locust bean gum, psyllium seed gum, quince seed gum, agar, carrageenan, carrageenates, furcellaran, pectin, gelatin, starches, methylcellulose, hydroxypropylcellulose, ethylhydroxyethylcellulose, carboxymethylstarch, hydroxymethylstarch, hydroxpropylstarch, dextrans, xanthan gum, propyleneglycol alginate, triethanolamine alginate, carboxymethyl locust bean gum, carboxymethyl guar gum, polyvinylpyrrolidone, polyvinyl alcohol, carboxyvinyl polymers, polyacrylic acid, polyacrylamide, and ethylene oxide polymers.

Claim 5
Dependent Claim
12 words
The method of claim 1, wherein said polishing agent is magnesium silicate.
Claim 6
Dependent Claim
29 words
The method of claim 1, wherein said effective amount of said polishing agent is 70% to 90% by weight, based on the weight of the dry powder dentifrice composition.
Claim 7
Dependent Claim
29 words
The method of claim 1, wherein said effective amount of said polishing agent is 75% to 85% by weight, based on the weight of the dry powder dentifrice composition.
Claim 8
Dependent Claim

Claim 9
Dependent Claim
28 words
The method of claim 1, wherein the amount of water added is approximately 20% to 90% by weight, based on the weight of the dry powder dentifrice composition.
Claim 10
Dependent Claim
28 words
The method of claim 1, wherein the amount of water added is approximately 40% to 50% by weight, based on the weight of the dry powder dentifrice composition.
Claim 11
Dependent Claim
65 words
A dry powder dentifrice composition capable of being instantly converted into a homogeneous dental cream comprising: (a) between 2 to 10% by weight, based on the weight of the dry powder dentifrice composition, of at least one readily water-soluble dry powdered gum, (b) an amount of magnesium or calcium silicate effective as a polishing agent, and (c) other components common to conventional dry dentifrice compositions.
Claim 12
Dependent Claim
65 words
A dry powder dentifrice composition capable of being instantly converted into a homogeneous dental cream comprising: (a) between 2 to 10% by weight, based on the weight of the dry powder dentifrice composition, of at least one readily water-soluble dry powdered gum, (b) an amount of magnesium or calcium silicate effective as a polishing agent, and (c) other components common to conventional dry dentifrice compositions.
