A stable easily removable hair rinse conditioner which provides good conditioning, styling ease, and manageability of hair, but does not build up with shampoo/anionic surfactants and is cost effective, consisting essentially of effective amounts of a dodecyl trimethyl quaternary ammonium compound, a saturated or unsaturated C.sub.14 -C.sub.22 alkanol, and a cyclic or linear silicone, in an aqueous vehicle.
The present invention relates to an aqueous opaque hair conditioner which comprises a monoalkyl quat from C14 to higher Carbon chain lengths (preferably C16 to C22) and a dialkyl quat which is a mixture of C16, C16 dialkyl quat and C18, C18 dialkyl quat. Also included is an amount of fatty alcohol to opacify the conditioner. Optionally, a silicone compound may be included. The monoalkyl quat may be in a ratio to the dialkyl quat of about 15:1 to about 2:1. The carbon chain lengths within the dialkyl quat are present in a weight ratio of about 1:3 to about 3:1 of C16,C16 to C18, C18. The fatty alcohol may be present in an amount from about 1% to about 10%.
The aqueous or aqueous-alcoholic hair treatment composition contains: A) 0.1 to 10 percent by weight polyvinylpyrrolidone or polyvinylpyrrolidone-vinyl acetate-copolymer; B) 0.1 to 9 percent by weight of at least one amphoteric surfactant, preferably a fatty acid amidoalkylbetaine or a fatty acid amidoalkylsulfobetaine; C) 0.1 to 5 percent by weight of at least one cationic surfactant, advantageously cetyltrimethylammonium chloride or bromide; and D) 0.1 to 2.0 percent by weight of at least one organic acid, preferably tartaric acid, glyoxalic acid, lactic acid or formic acid.
A method of imparting improved conditioning properties to hair comprising treating the hair with a clear conditioning composition comprising a quaternary ammonium compound, such as dicetyldimonium chloride; an amidoamine compound having the general formula: ##STR1## 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, methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, R.sub.4 is methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, and Y is a heterocyclic nitrogen-containing moiety, like morpholine or pyridine; a volatile conditioning agent, such as a volatile hydrocarbon compound or a volatile silicone compound, like cyclomethicone; a solubilizing nonionic surfactant, like lauryl pyrrolidone; and a polyhydric compound, such as a glycol, a triol or a polyol, like hexylene glycol. The clear conditioning composition unexpectedly provides improved hair-conditioning properties, such as wet and dry feel, wet and dry combing, less coating, increased body and overall hair condition to treated hair.
A method of imparting improved conditioning properties to hair comprising treating the hair with a composition comprising a water-soluble quaternary ammonium compound, such as cetrimonium chloride; an oil-soluble, water-dispersible quaternary ammonium compound, such as distearyldimonium chloride; an acid-neutralized amidoamine compound, wherein an amidoamine having the general formula: ##STR1## 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, methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, R.sub.4 is methyl, ethyl or a hydroxyalkylene group containing from one to about three carbon atoms, and Y is a heterocyclic nitrogen-containing moiety, like morpholine or pyridine, is neutralized with a suitable acid, such as the amidoamine compound stearamidoethylethanolamine neutralized with phosphoric acid; and a low molecular weight polydimethylsiloxane compound, such as cyclomethicone. The method and composition unexpectedly provide improved hair-conditioning properties such as wet feel, wet and dry combing, manageability, sheen, luster, body and overall hair condition.
