Abstract
Abstract A dentifrice composition containing as the active foaming agent (I) a monoalkyl phosphate ester salt and (II) a dialkyl phosphate ester salt, wherein said alkyls have 10 to 14 carbon atoms and the weight ratio of I:II is from 100:0 to 70:30.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
A dentifrice composition in which the active foaming component consists essentially of a monoalkyl phosphate ester salt having the formula (I): ##STR7## wherein R is alkyl or alkenyl having 10 to 14 carbon atoms, X 1 is alkali metal or alkanolamine, and X 2 is hydrogen, alkali metal or alkanolamine, and a dialkyl phosphate ester salt having the formula (II): ##STR8## wherein R and X 1 are the same as defined above, the mixing weight ratio of said monoalkyl phosphate ester salt (I) to said dialkyl phosphate ester salt (II) being in the range of from 100:0 to 70:30.
Claim 2
Dependent Claim
99 words
A dentifrice composition in which the active foaming component consists essentially of a monoalkyl phosphate ester salt having the formula (I): ##STR7## wherein R is alkyl or alkenyl having 10 to 14 carbon atoms, X 1 is alkali metal or alkanolamine, and X 2 is hydrogen, alkali metal or alkanolamine, and a dialkyl phosphate ester salt having the formula (II): ##STR8## wherein R and X 1 are the same as defined above, the mixing weight ratio of said monoalkyl phosphate ester salt (I) to said dialkyl phosphate ester salt (II) being in the range of from 100:0 to 70:30.
Claim 3
Dependent Claim
54 words
A dentifrice composition as set forth in claim 1 wherein the sum of the amounts of said alkyl phosphate esters of formula (I) and formula (II) is from 0.2 to 5.0% by weight, based on the total weight of said dentifrice composition, the balance of said dentifrice composition consisting essentially of conventional dentifrice ingredients.
Claim 4
Dependent Claim
41 words
A dentifrice composition as set forth in claim 1 wherein the mixing weight ratio of said monoalkyl phosphate ester salt of formula (I) to the dialkyl phosphate ester salt of formula (II) is in the range of from 100:0 to 85:15.
Claim 5
Dependent Claim
29 words
A dentifrice composition as set forth in claim 1 wherein in said monoalkyl phosphate ester of formula (I), X 1 is sodium or potassium and X 2 is hydrogen.
Claim 6
Dependent Claim
16 words
A dentifrice composition as claimed in claim 1 wherein R contains 12 to 14 carbon atoms.
Claim 7
Dependent Claim
79 words
A dentifrice composition as claimed in claim 1 wherein the sum of the amounts of said formula (I) compound and said formula (II) compound is from one to 4 percent by weight, and the balance of said composition consists essentially of from 0.3 to 5 percent by weight of a dentally acceptable binder, from 5 to 40 percent by weight of a dentally acceptable humectant and from 5 to 70 percent by weight of a dentally acceptable polishing agent.
