CLAIMS

1. A dentifrice composition which contains a quaternary
ammonium organosiloxane having the formula



wherein R1 is an alkoxy group having from 1 to 5 carbon atoms,

R2 is an alkylene group having from 1 to 25 carbon atoms and

R3 , R4 and R5 are, individually, alkyl groups of from 1 to 25 carbon atoms, and X is an anion.

2. A dentifrice composition in accordance with claim 1 wherein X is selected from chlorine, bromine, fluorine and iodine.

3. A dentifrice composition according to claim 2 wherein said composition contains at least about 0.05% by weight of said quaternary ammonium organosiloxane.

A dentifrice composition according to claim 3 wherein R2 is methoxy, R2 is an alkylene group having from 1 to 10 carbon atoms, R3 is an alkyl group having from 10 to 20 carbon atoms, R4 and R5 are, individually, methyl groups, and X is chlorine.

A dentifrice composition according to claim 4 wherein R2 is a propylene group and R3 is an octadecyl group.

6. The method of inhibiting plaque formation by contacting teeth with an effective amount of a dentifrice composition which contains a quaternary ammonium organosiloxane compound having the formula



wherein R1 is an alkoxy group having from 1 to 5 carbon atoms, R2 is an alkylene group having from 1 to 25 carbon atoms, and R 3, R4 and R5 are, individually, alkyl groups of from 1 to 25 carbon atoms, and X is an anion.

7. The method of claim 6 wherein X is selected from chlorine, bromine, fluorine and iodine.

8. The method of claim 7 wherein R1 is methoxy, R2 is an
alkylene group having from 1 to 10 carbon atoms, R3 is an alkyl group having from 10 to 20 carbon atoms, R4
and R5 are, individually, methyl groups, and X is chlorine.

9. The method of claim 8 wherein R2 is a propylene group
and R3 is an octadecyl group.

10. The method of claim 6 wherein said teeth are contacted by a composition comprising at least about 0.05% by weight of said quaternary ammonium organosiloxane compound.
