Abstract
A conditioning shampoo containing an anionic cleansing surfactant, in an amount of about 5% to about 65% by weight, preferably about 5% to about 25% by weight, e.g., (C.sub.12 -C.sub.22) alkyl sulfate, and/or a long chain (C.sub.12 -C.sub.22) partially or fully ethoxylated alkyl sulfate, and/or a long chain (C.sub.12 -C.sub.22) alkyl sulfonate, and a combination of cationic polymers comprising (1) a cationic (protonated) polyethyleneimine in an amount of about 0.1% to about 4% by weight, preferably about 0.1% to about 1% by weight, and (2) a cationic oil-soluble, water-dispersible, cross-linked quaternary acrylate/acrylamide copolymer (Polyquaternium 32), in an amount of about 0.1% to about 20% by weight of the composition, provides excellent foaming, conditioning and stability, without settling of water-insoluble materials due to anionic-cationic complexing. The composition preferably also includes one or more silicone conditioning agents, and has extended product stability, excellent overall conditioning to human hair, particularly superior wet and dry combing properties, and unexpectedly maintains very high levels of foam.
