Abstract

A sulphate-free-surfactant cleansing composition comprising, in an aqueous continuous phase: a total amount of anionic surfactant and amphoteric surfactant consisting of: (i) from 3 wt % to 13 wt %, by weight of the total composition at 100% activity, of an alpha olefin sulfonate anionic surfactant of general formula (I): R¹—CH═CH—CH₂—SO₃-M⁺ (I) in which R¹ is selected from linear or branched alkyl groups having from 11 to 13 carbon atoms and mixtures thereof; and M is a solubilizing cation; (ii) from 1 to 8 wt %, by weight of amphoteric surfactant, which is cocamidopropyl betaine; (iii) from 0.05 wt % to 0.5 wt % of a cationic polymer; (iv) from 0.3 to 2.8 wt % an inorganic electrolyte; and (v) water; in which the weight ratio of (i) to (ii) ranges from 2:1 to 1:4 and the pH of the composition is from 3 to 6.5; and wherein the composition has a viscosity of from 2,500 to 25,000 mPa·s, when measured using a TA Instruments Discovery Hybrid Rheometer; parallel 40 mm sandblasted plates, peak hold protocol at 4 s−¹; at 30° C.
