Abstract
A composition consisting essentially of a siloxane having substituents that provide attachment to the hair, surfactants, additives that provide freeze-thaw stability, and water is disclosed. The composition may also contain thickeners, and additives that reduce static electricity build-up, and fly-away. A method of conditioning hair which comprises applying to the hair the composition as defined above is also disclosed.
Claims6
A hair conditioning composition which is a stable dispersion of silicone and is formed by dispersing with shear a siloxane polymer into an aqueous phase, the composition consisting essentially of 0.1 to 61 percent by weight of
- (A) a siloxane having the general formula R.sub.a X.sub.3-a Si(OSiX.sub.2).sub.n (OSiX.sub.b R.sub.2-b).sub.m OSiX.sub.3-a R.sub.a wherein R is a monovalent radical having the general formula --C.sub.y H.sub.2y Z wherein y has a value of 2 to 8 and Z is selected from the group consisting of --NR'CH.sub.2 CH.sub.2 NR'.sub.2, --COOH, --SCH.sub.2 COOH, ##STR4## --NR'.sub.2,--N.sup.+ R'.sub.3 A.sup.-, --N.sup.+ R'H.sub.2 A.sup.31, and --NR'CH.sub.2 CH.sub.2 N.sup.+ R'H.sub.2 A-, wherein R;
- is selected from the group consisting of hydrogen, phenyl, benzyl, and monovalent saturated hydrocarbon radicals composed of 1 to 20 carbon atoms and A.sup.- is a halogen;
- X is selected from the group consisting of hydrogen, phenyl, hydroxyl, and saturated hydrocarbon radicals composed of 1 to 8 carbon atoms;
- a has a value of 0 to 3;
- b has a value of 0 to 1;
- and n+m has a value of 1 to 2000 with n having a value of 0 to 1999 and m having a value of 1 to 2000;
- 0. 02 to 11.6 percent by weight of
- (B) a surfactant selected from the group consisting of cationic, nonionic, and anionic surfactants;
- 0.003 to 2 percent by weight of
- (C) a water soluble polyhydroxy alcohol;
- and
- 0.16 to 99.88 percent by weight of
- (D) water.
