A personal cleansing comprising, in an aqueous continuous phase: a total amount of anionic surfactant, amphoteric surfactant and zwitterionic surfactant consisting of: (i) from 3 wt % to less than 7 wt %, by weight of the total composition at 100% activity, of an alkyl ether sulfate anionic surfactant of general formula (I): R—O—(CHCH—O)—SO−M+ in which R is selected from linear or branched alkyl groups having from 10 to 14 carbon atoms and mixtures thereof; n is a number that represents the average degree of ethoxylation and ranges from 1.5 to 2.5; and M is a solubilizing cation; (ii) a betaine surfactant selected from an amido betaine amphoteric surfactant of general formula (II): where m is 2 or 3; RC(O) is selected from linear or branched, saturated or unsaturated acyl groups having from 8 to 22 carbon atoms and mixtures thereof; and Rand Rare each independently selected from alkyl, hydroxyalkyl or carboxyalkyl groups having from 1 to 6 carbon atoms and mixtures thereof; an alkyl betaine of general formula (III): wherein R is a coco chain, and mixtures thereof; and (iii) one or more dispersed benefit agents selected from emulsified silicones with a mean diameter (D3,2) of 4 micrometres or less; in which the weight ratio of (i) to (ii) ranges from 1 to 1 to 4.5:1 and the pH of the composition is from 3 to 6.5, and the combined amount of (i) and (ii) ranges from 5 wt % to 9 wt % (by weight based on the total weight of the composition); gives mildness benefit without compromising on cleaning and rheology; and wherein the composition further comprises an inorganic electrolyte.
