Abstract
A pretreatment conditioner comprising an aqueous system of from about 0.1 to about 20 weight percent of a cationic cellulose derivative quaternized with fatty C.sub.10 -C.sub.18 alkyl groups, from about 0.05 to about 20 weight percent of a quaternary polymer; and (3) from about 0.02 to about 10 weight percent of a quaternary ammonium salt, with each weight percentage reflecting the active weight percent of the ingredient, based on the total weight of the composition. The composition is useful in a method of pretreatment conditioning of hair comprising applying to hair the composition followed by shampooing with an anionic shampoo.
Claims8
A pre-shampoo conditioning composition comprising an aqueous system of:
- (a) from about 0.1 to about 20 weight percent of a steardimonium hydroxypropyl oxythyl cellulose having a molecular weight of from about 75,000 to about 125,000 daltons;
- (b) from about 0.05 to about 20 weight percent of a quaternary polymer selected from the group consisting of polydiallyldimethylammonium chloride and polydiallyldimethylammonium bromide;
- and
- (c) from about 0.2 to about 10 weight percent of a dehenamidopropyl dihydroxypropyl dimonium chloride as represented by the formula:
- ##STR9## wherein said weight percentages are the active weight percentage of each ingredient, based on total weight of the composition
A method of pretreatment conditioning of hair comprising:
- (I) applying to hair a conditioning composition comprising an aqueous system of:
- (a) from about 0.1 to about 20 weight percent of a steardimonium hydroxypropyl oxyethyl cellulose:
- (b) from about 0.05 to about 20 weight percent of a quaternary polymer selected from the group consisting of polydiallyldimethylammonium chloride and polydiallyldimethylammonium bromide;
- (c) from about 0.02 to about 10 weight percent of a behenamidopropyl dihydroxypropyl dimonium chloride as represented by the formula:
- ##STR10## wherein said weight percentages are the active weight percentage of each ingredient, based on total weight of the composition;
- (II) shampooing said conditioned hair with an anionic shampoo;
- and
- (III) rinsing said shampoo from hair.
