  • Gelled near tricritical point compositions
    Patent number: 5585034
    Abstract: The present invention relates to an aqueous gelled cleaning composition which is useful for the removal of grease or tar without any mechanical action. In particular, the instant compositions are derived from three liquid phases which merge together at the tricritical point to form one continuum forming the gelled aqueous cleaning composition, wherein the three phases incorporate at least a polar solvent, a non-polar solvent or weakly polar solvent and a water soluble or water low molecular weight water dispersible amphiphile and the composition contains a noncrosslinked polymer.
    Type: Grant
    Filed: October 25, 1995
    Date of Patent: December 17, 1996
