Abstract
Shampoo compositions comprise (a) from about 5% to about 50% of one or more detersive surfactants; (b) a dispersed gel network phase comprising: (i) at least about 0.05% of one or more fatty amphiphiles; (ii) at least about 0.01% of one or more secondary surfactants; and (iii) water; (c) at least about 0.05% of a galactomannan polymer derivative with a net positive charge and having a mannose to galactose ratio of greater than 2:1 on a monomer to monomer basis, wherein the galactomannan polymer derivative has: (i) a molecular weight from about 1,000 to about 10,000,000; and (ii) a cationic charge density from about 0.7 meq/g to about 7 meq/g; and (d) at least about 20% of an aqueous carrier; all by weight of the shampoo composition.
