    Abstract: A pH greater than 7 aqueous ozonized cleaning composition can be used for cleaning a tenacious residue or film from solid surfaces. The cleaning properties can be potentiated by additive materials. Ozone, generated by electrical discharge, can be blended into effective aqueous cleaning compositions that can efficiently clean proteinaceous, oily or carbohydrate soil from a variety of surfaces. Immediately after ozone generation, the ozone containing gas stream comprising ozone and the residual air is injected through a hose into an aqueous potentiating additive containing carrier solution, forming a cleaning solution which is applied immediately to a soiled solid surface to remove a contaminating residue or film.

    Abstract: Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric carboxylate surfactant material in combination with cationic destabilizer or flocculent materials. Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream. The treated aqueous stream is environmentally compatible. Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil. The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent. Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 10 ppm.

    Abstract: Floor finishes can be stripped using a substantially nonchlorinated concentrate comprising a floor finish dissolver and an at least partially water-unactivated water thickener. The concentrate is diluted with water at an intended use location to activate the water thickener and noticeably increase within sixty minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.
