High foaming liquid shampoo composition
First Claim
1. A liquid shampoo having a viscosity greater than about 6400 centipoise comprising by weight about 2 to 25 percent nonionic surfactant, about 1 to 5 percent anionic surfactant, about 4 to 20 percent amphoteric surfactant, about 1 to 5 percent alkanolamide, about 1 to 5 percent polyoxyalkylene glycol di fatty acid ester and about 40 to 85 percent by weight water, said nonionic surfactant being a cogeneric mixture of conjugated polyoxybutylene-polyoxyethylene compounds containing in their structure oxybutylene groups, oxyethylene groups and an organic radical derived from a water-soluble organic compound containing a plurality of reactive hydrogen atoms and 2 to 12 carbon atoms;
- the compounds being characterized in that all of the oxybutylene groups are present in polyoxybutylene chains that are attached to the organic radical at the site of a reactive hydrogen atom thereby constituting a polyoxybutylene polymer;
the oxyethylene groups being attached to the polyoxybutylene polymer in polyoxyethylene chains;
the average molecular weight of the polyoxybutylene polymers in the mixture being at least 500, as determined by hydroxyl number, and the oxyethylene groups present constituting 65 to 80 percent, by weight, of the mixture.

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.
