Abstract
It has been found in accordance with the instant invention that the viscosity of a shampoo formulation based on a blend of amphoteric and nonionic surfactants could be considerably enhanced by replacement of a part of the amphoteric surfactant with an anionic surfactant. The shampoo compositions also contain as essential ingredients both an alkanolamide and a polyoxyalkylene glycol fatty ester. These shampoo products are characterized by increased viscosity as well as mildness towards the eyes and superior foam compared to some leading commercial products. The nonionic surfactant is a cogeneric mixture of conjugated polyoxybutylene-polyoxyethylene compounds containing in their structure oxybutylene groups, oxyethylene groups and an organic radical derived from an organic compound containing a pluarlity of reactive hydrogen atoms.
