Abstract
Abstract A dentifrice composition is provided containing a quaternary ammonium organosiloxane having the formula ##STR1## wherein R 1 is an alkoxy group having from 1 to 5 carbon atoms, R 2 is an alkylene group having from 1 to 25 carbon atoms, and R 3 , R 4 and R 5 are, individually, alkyl groups of from 1 to 25 carbon atoms, and X is an anion, preferably selected from chlorine, bromine fluorine and iodine. A method of inhibiting plaque formation on teeth in an oral environment is also provided.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
96 words
A dentifrice composition which consists essentially of at least one ingredient selected from the group consisting of caries prophylactic agents, soaps, detergents, flavoring agents, sweetening agents and humectants and at least about 0.05% by weight of a quaternary ammonium organosiloxane having the formula ##STR6## wherein R 1 is an alkoxy group having from 1 to 5 carbon atoms, R 2 is an alkylene group having from 1 to 25 carbon atoms, and R 3 , R 4 and R 5 are, individually, alkyl groups of from 1 to 25 carbon atoms, and X is an anion.
Claim 2
Dependent Claim
96 words
A dentifrice composition which consists essentially of at least one ingredient selected from the group consisting of caries prophylactic agents, soaps, detergents, flavoring agents, sweetening agents and humectants and at least about 0.05% by weight of a quaternary ammonium organosiloxane having the formula ##STR6## wherein R 1 is an alkoxy group having from 1 to 5 carbon atoms, R 2 is an alkylene group having from 1 to 25 carbon atoms, and R 3 , R 4 and R 5 are, individually, alkyl groups of from 1 to 25 carbon atoms, and X is an anion.
Claim 3
Dependent Claim
18 words
A dentifrice composition in accordance with claim 1 wherein X is selected from chlorine, bromine, fluorine and iodine.
