Abstract
A clear or translucent, stable, compact shampoo composition exhibiting good wet conditioning. The shampoo contains a cationic polymer and a surfactant system. The cationic polymer has an average molecular weight from about 50,000 g/mol to about 1,200,000 g/mol. The sulfate system contains an amino acid based surfactant and is substantially free of sulfate-based surfactants. The shampoo also has a relatively low viscosity.
