Abstract:
1. A composition for washing and conditioning keratin fibers, comprising, in a cosmetically acceptable medium: (a) at least one washing base comprising at least one anionic surfactant; and (b) at least one amphiphilic diblock copolymer chosen from anionic and nonionic amphiphilic diblock copolymers, comprising a hydrophilic block and a hydrophobic block, wherein the hydrophobic block comprises at least 80 mol % of at least one water-insoluble monomer; wherein said at least one amphiphilic diblock copolymer is not a diblock copolymer of ethylene oxide and of propylene oxide, a urethane block copolymer, or a siloxane block copolymer; wherein said at least one amphiphilic diblock copolymer has a ratio of the number of monomer units in the hydrophilic block to the number of monomer units in the hydrophobic block ranging from 7 to 24; and wherein the amount of the at least one washing base ranges from 4% to 50% by weight, relative to the total weight of the composition.
