  • 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.

  • Patent number: 5523013
    Abstract: A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions.
