Abstract
The invention provides an aqueous shampoo composition comprising: (i) one or more anionic cleansing surfactants; (ii) preferably, discrete, dispersed droplets of a water-insoluble conditioning agent with a mean droplet diameter (D.sub.3,2) of 4 micrometers or less; (iii) one or more cationic polymers (A) selected from cationically modified acrylamide polymers having a cationic charge density at pH7 of less than 1.0 meq per gram, cationically modified celluloses and mixtures thereof, and (iv) one or more cationic polymers (B) selected from cationically modified acrylamide polymers having a cationic charge density at pH7 of greater than 1.0 meq per gram, cationically modified polygalactomannans, and mixtures thereof, wherein the composition comprises a cationic polymer other than a cationically modified acrylamide polymer.
