Abstract

A personal cleansing composition comprising:

• a. from about 5% to about 50% by weight of an anionic detersive surfactant;
• b. from about 0.025% to about 5% by weight of a first cationic polymer having a cationic charge density of less than about 4 meq/gm, wherein said first cationic polymer forms an isotropic coacervate;
• c. from about 0.025% to about 5% by weight of a second cationic polymer having a cationic charge density of greater than or equal to about 4 meq/gm, wherein said second cationic polymer forms a lyotropic liquid crystal coacervate; and
• d. from about 20% to about 94% by weight of water.
