The invention discloses cleaning compositions which employ a synergistic combination of an ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.

Non-aqueous cleaner for vegetable oil soils

The invention discloses cleaning compositions which employ a synergistic combination of a ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.

The present invention relates to the field of membrane separation processes and clean in place compositions for cleaning such membranes. The cleaning compositions can remove proteins, fats, and other food, beverage, and brewery based soils and offer an environmentally friendly alternative surfactant system to NPE. According to the invention, surfactants and polymers useful for this process are unpredictable and specific surfactants, polymers, and combinations of the same are disclosed for use alone, as part of a cleaning composition. Methods of use of the same are also included.

Surfactant blends for cleaning filtration membranes

The present invention relates to aqueous, sulfuric acid cleaners which employ the use of nitric acid as a corrosion inhibitor for cleaning metal and other surfaces, particularly stainless steel and for inhibiting corrosion. Method of use and manufacturing of the same are also disclosed.

Acid cleaning and corrosion inhibiting compositions comprising a blend of nitric and sulfuric acid

The present invention relates to sulfuric/nitric blended acid cleaners which employ the use of ethoxylated amines and/or ethoxylated alcohols as a corrosion and stain inhibitor in the vapor phase for cleaning metal and other surfaces, particularly stainless steel. Method of use and manufacturing of the same are also disclosed.

Aqueous acid cleaning, corrosion and stain inhibiting compositions in the vapor phase comprising a blend of nitric and sulfuric acid

The present invention relates to methods for removing or preventing scale formation in a liquid food processing operation. The present invention also relates to methods and compositions for increasing the solubility of insoluble calcium salts in an acidic environment. Aqueous antiscalant solutions comprising soluble magnesium salts are used to prevent the precipitation of insoluble calcium salts and/or to increase the solubility of insoluble calcium salts.
