摘要：
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-(CH2CH2-O)n-SO3-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； R1C(O) is selected from linear or branched, saturated or unsaturated acyl groups having from 8 to 22 carbon atoms and mixtures thereof； and R2 and R3 are 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.Une composition d'hygiène personnelle comprend, dans une phase continue aqueuse : une quantité totale de tensioactif anionique, de tensioactif amphotère et de tensioactif zwitterionique incluant : (i) de 3 % en poids à moins de 7 % en poids, en poids de la composition totale à 100 % d'activité, d'un tensioactif anionique d'alkyle éther sulfate de formule générale (I) : R-O-(CH2CH2-O)n-
