Abstract
Abstract A composition, used to groom hair, consisting essentially of an organopolysiloxane having at least one alkylamino substituent and at least one substituent selected from the group consisting of oxyalkylene, polyoxyalkylene, and hydroxyalkyl groups, said organopolysiloxane having a viscosity range of 1 to 100,000 centistokes at 25 DEG C., is disclosed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
A hair grooming composition consisting essentially of 0.01 to 10 percent by weight of an organopolysiloxane having at least one alkylamino substituent having the general formula --R'(NHCH.sub.2 CH.sub.2).sub.a NR.sup.2 R.sup.3 wherein R' is a divalent hydrocarbon group, R 2 and R 3 are selected from the group consisting of hydrogen and monovalent hydrocarbon groups, and a has a value of 0 to 5 and at least one substituent selected from the group consisting of oxyalkylene, polyoxyalkylene, and hydroxyalkyl groups, the oxyalkylene and polyoxyalkylene substituents having the general formula --R.sub.b.sup.4 O(C.sub.m H.sub.2m O).sub.c R.sup.5 wherein R 4 is a divalent hydrocarbon group, R 5 is selected from the group consisting of hydrogen and end-blocking groups, b has a value of 0 to 1, m has a value of 1 to 5, and c has a value of 1 to 100, and the hydroxyalkyl substituent having the general formula R 4 OH wherein R 4 is a divalent hydrocarbon group, said organopolysiloxane having a viscosity range of 1 to 100,000 centistokes at 25° C. and a carrier selected from the group consisting of an aqueous solution, an emulsion and an organic solvent.
Claim 2
Dependent Claim
190 words
A hair grooming composition consisting essentially of 0.01 to 10 percent by weight of an organopolysiloxane having at least one alkylamino substituent having the general formula --R'(NHCH.sub.2 CH.sub.2).sub.a NR.sup.2 R.sup.3 wherein R' is a divalent hydrocarbon group, R 2 and R 3 are selected from the group consisting of hydrogen and monovalent hydrocarbon groups, and a has a value of 0 to 5 and at least one substituent selected from the group consisting of oxyalkylene, polyoxyalkylene, and hydroxyalkyl groups, the oxyalkylene and polyoxyalkylene substituents having the general formula --R.sub.b.sup.4 O(C.sub.m H.sub.2m O).sub.c R.sup.5 wherein R 4 is a divalent hydrocarbon group, R 5 is selected from the group consisting of hydrogen and end-blocking groups, b has a value of 0 to 1, m has a value of 1 to 5, and c has a value of 1 to 100, and the hydroxyalkyl substituent having the general formula R 4 OH wherein R 4 is a divalent hydrocarbon group, said organopolysiloxane having a viscosity range of 1 to 100,000 centistokes at 25° C. and a carrier selected from the group consisting of an aqueous solution, an emulsion and an organic solvent.
