- 7. The composition of claim 1 wherein the silicone compound has a general structure: ##STR21## wherein R is an alkyl group having one to about 22 carbon atoms; m is a numeral from about five to about fifty, and X is a water-soluble anion.
- 8. The composition of claim 7 wherein the silicone compound has the structure: ##STR22## wherein m is a numeral from about 10 to about 30.
- 9. The composition of claim 1 wherein the silicone compound is Quaternium 80.
- 10. The composition of claim 1 wherein the silicone compound is present in an amount of about 0.2% to about 4% by weight of the composition.
- 11. The composition of claim 1 wherein the silicone compound is present in an amount of about 0.2% to about 3% by weight of the composition.
- 12. The composition of claim 1 wherein the aqueous carrier further comprises about 1% to about 50% by weight relative to the total weight of the carrier of a lower alcohol, a glycol ether, or a combination thereof.
- 13. The composition of claim 1 wherein the amidoamine compound is lauramidopropyldimethylamine and the silicone compound is Quaternium 80, wherein the amidoamine compound is neutralized with an organic acid.
- 14. A method of conditioning the hair comprising contacting the hair with a clear conditioning composition for a sufficient time to condition the hair, said composition comprising:
- (a) about 0.4% to about 15% by weight of an amidoamine salt, wherein the amidoamine salt comprises:
- (i) an amidoamine compound having a general structure: ##STR23## or a mixture thereof, wherein R.sub.1 is a fatty acid chain containing from about 11 to about 21 carbon atoms; R.sub.2 is an alkylene group containing from two to about four carbon atoms; R.sub.3 is hydrogen, a methyl group, an ethyl group or a hydroxyalkylene group containing from one to about three carbon atoms; R.sub.4 is a methyl group, an ethyl group or a hydroxyalkylene group containing from one to about three carbon atoms; and Y is an organic heterocyclic nitrogen-containing moiety, and
- (ii) a sufficient amount of a suitable acid to neutralize the amidoamine compound and provide a composition pH of about 4 to about 7;
- (b) about 0.1% to about 5% by weight of a silicone compound having at least two quaternary ammonium moieties; and
- (c) an aqueous carrier,
- wherein the amidoamine compound is present in a sufficient amount to provide a clear composition, and
- wherein the amidoamine compound and the silicone compound are present in a weight ratio of amidoamine compound to silicone compound of at least about 2.8 to 1, such that the composition is clear when free of a coupling agent.
- 15. The method of claim 14 further comprising rinsing the hair with water after contacting the hair with the clear conditioning composition.
- 16. The method of claim 14 wherein the silicone compound has a general structure: ##STR24## wherein R is an alkyl group having one to about 22 carbon atoms; m is a numeral from about five to about fifty; and X is a water-soluble anion.
- 17. The method of claim 16 wherein the silicone compound has the structure: ##STR25## wherein m is a numeral from about 10 to about 30.
