  • Patent number: 5922664
    Abstract: Aqueous detergent concentrates containing a mixture of two or more surfactants having a differing resistance to electrolytic salting out in the form of micellar solutions and having pourable viscosities are converted into lamellar solutions upon dilution with water where the dispersion contains a viscosity promoting electrolyte present at a narrow range of concentration. Transformation from the micellar phase to the lamellar phase produces an increase in viscosity such that the diluted concentrate has a viscosity equal to or higher than the viscosity of the original concentrate.
