These products typically comprise an anionic cleansing 15 surfactant in combination with a conditioning agent. Amongst the most popular conditioning agents used in shampoo compositions are oily materials such as mineral oils, naturally occurring oils such as triglycerides and silicone polymers. These are generally present in the shampoo as 20 dispersed hydrophobic emulsion droplets. Conditioning is achieved by the oily material being deposited onto the hair resulting in the formation of a film. However, many shampoo compositions do not provide a 25 sufficient level of deposition of conditioning agent onto the hair and skin during the cleansing process. Without such deposition, large proportions of conditioning agent are rinsed away during the cleansing process and therefore provide little or no conditioning benefit. 30 WO 2007/065537 PCT/EP2006/010954 - 2 - one known method for improving deposition of a conditioning agent from such shampoo compositions involves the use of cationic deposition polymers. These polymers may be synthetic or natuxal polymers that have been modified with 5 cationic substituents. A problem associated with the use of cationic deposition polymers is that is difficult to obtain a good balance of conditioning benefits at different stages of the shampooing 10 process. For example, some cationic deposition polymers are effective at impx-oving wet stage hair sensory attributes during the stages of washing and rinsing, but give an undesirable haix* 15 feel after drying. The present inventors have found that this problem can be overcome by using a specific combination of cationic polymex-s in a shampoo composition which comprises small 20 droplets of a water-insoluble oily conditioning agent. In particular", shampoo compositions of the invention give improved wet conditioning benefits, such as soft feel, smooth feel and combability when wet, with a reduction in 25 dry hair sensory negatives such as the heavy, gx-easy or coated feel that many consumers experience when high charge density cationic polymex-s and oily conditioning agents are combined in shampoos. WO 2007/065537 PCT/EP2006/010954 - 3 - SUMMARY OF THE INVENTION The present invention provides an aqueous shampoo 5 composition comprising: (i) one or more anionic cleansing surfactants; (ii) discrete, dispersed droplets of a water-insoluble ID conditioning agent with a mean droplet diameter (D3,2) of 4 micrometres or less; (iii) one or more cationic polymers (A) selected from cationically modified acrylamide polymers having a cationic 15 charge density at pH7 of less than 1.0 meg per gram, cationically modified celluloses and mixtures thereof, and 2 0 (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 meg per gram, cationically modified polygalactomarnnans, and mixtures thereof, 25 wherein the composition comprises a cationic polymer other than a cationically modified acrylamide polymer.
