The present invention is directed to conditioning shampoo compositions which comprise (A) from about 5% to about 50% by weight of an anionic surfactant component selected from the group consisting of anionic surfactants, zwitterionic or amphoteric surfactants having an attached group that is anionic at the pH of the composition, and combinations thereof; (B) from about 0.05% to about 3% by weight of an organic, cationic, hair conditioning polymer; (C) from about 0.01% to about 1.0% by weight of a water insoluble, synthetic ester having a viscosity of from about 1 to about 300 centipoise, and which conforms to either of the following formulas wherein R1 is an alkyl, alkenyl, hydroxyalkyl or hydroxyalkenyl group, having from 7 to 9 carbon atoms; n is a positive integer having a value of from 2 to 4; R2 is an alkyl, alkenyl, hydroxyalkyl or hydroxyalkenyl group, having from 8 to 10 carbon atoms; and Y is an alkyl, alkenyl, or a hydroxy or carboxy substituted alkyl or alkenyl, having from 2 to 20 carbon atoms; and (D) from about 20% to about 94% by weight of water, wherein the synthetic ester content represents from about 2.5% to about 100% by weight of the total liquid fatty ester content of the composition. It has been found that the use of select synthetic esters (diesters, triesters or tetraesters) in the shampoo compositions provide improved wet hair conditioning performance by eliminating or minimizing the slimy, excessively conditioned, wet hair feel often associated with the use of a cationic hair conditioning polymers.
