Sulphate-free and nonionic surfactant-free cleansing composition

Abstract

1. A sulphate free cleansing composition for hair and scalp comprising, in an aqueous continuous phase: a total amount of anionic surfactant, amphoteric surfactant and zwitterionic 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): R—CH═CH—CH—SOM(I) in which Ris 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 6%, by weight of an amphoteric or zwitterionic surfactant, selected from an alkyl betaine of general formula (II) R—N(CH)—CH—COOM(II) wherein R=C12 (Lauryl) or Coco derived; an alkyl hydroxy sultaine of general formula (III), R—N+(CH)—CH—CH(OH)—CH—SOM(III) wherein R=C12 (Lauryl) or Coco derived; an alkyl aminopropyl hydroxy sultaine of general formula (IV), R—CO—NH—(CH)—N(CH)—CH—CH(OH)—CH—SOM(IV) wherein R=C12 (Lauryl) or Coco derived; an alkyl amphoacetate of general formula (V), R—CO—NH—(CH)—N(CH—CH—OH)(CH—COOM) (V) wherein R=C12 (Lauryl) or Coco derived; and mixtures thereof; (iii) from 0.05 to 0.9 wt % of a cationic conditioning polymer; (iv) from 0.05 to 10 wt % of a silicone emulsion; (v) a cationic deposition polymer; (vi) an inorganic electrolyte; and (vii) water in which the weight ratio of (i) to (ii) ranges from 1:1 to 6:1 and the pH of the composition is from 3 to 6.5.
