Claim Text:
1. An isotropic, flowable, aqueous cleansing composition comprising: an aqueous blend of N-acyl glycinates of Formula I, and O-acyl isethionates of Formula II; wherein, R is selected from C R M is a cation selected from Li prepared by the process comprising A) reacting more than one equivalent of fatty acid chloride with alkali metal or ammonium salts of hydroxyalkyl sulphonates to obtain compounds of Formula II, and B) reacting unreacted fatty acid chloride in the product of step (A) with glycine in the presence of a base under aqueous Schotten Baumann reaction conditions to yield compounds of Formula I; the weight ratio of N-acyl glycinates of Formula I to O-acyl isethionates of Formula II is in range of 1.0:1.0 to 10.0:1.0, and a solubilizing surfactant wherein the weight ratio of the aqueous blend of N-acyl glycinates of Formula I, and O-acyl isethionates of Formula II: the solubilizing surfactant is from 1.0:0.1 to 1.0:1.0, and the pH of the aqueous cleansing composition is 5.0 to 6.0.
