Abstract: The present invention pertains to liquid homogeneous substantially unbuilt enzyme containing detergent compositions. These liquid compositions contain a major amount of a surfactant mixture comprising an ethoxylated nonionic surfactant and a synthetic anionic surfactant, a low level of a polyacid, free calcium ions, a proteolytic enzyme and a liquid carrier. The liquid compositions of this invention are from a performance standpoint comparable to granular built heavy duty detergent compositions. In respect to the comparable known liquid detergent state of the art, the compositions herein are capable of providing superior cleaning performance and excellent storage stability, particularly as regards the enzymatic activity.

Abstract: The present invention relates to liquid, concentrated, homogeneous, stable, heavy duty detergent compositions. Such compositions contain a polyethoxylated nonionic detergent compound, a minor amount of a polyacid having at least one pK value of at least 5.0, and a liquid carrier, whereby the pH of the liquid composition has a pH in the range between 6.0 and 7.5. The compositions can also contain mixtures of polyethoxylated nonionic detergent compounds, additional amounts of synthetic, anionic detergent compounds, minor amounts of brighteners, suds-regulating and pH-regulating agents, perfumes, dyes and other usual liquid detergent compound additives. Such compositions show enhanced cleaning performance, particularly on bleach-sensitive stains, and have excelled stability on storage.

Abstract: Hydrophilic surfaces on lithographic duplicators are cleaned by light rubbing with a liquid composition comprising levigated alumina of small particle size, a surfactant, an aluminum salt and an acidifying agent all dispersed in water. The surface is then rinsed with water to remove the cleaning composition, and is found to be in an ink-free moisture receptive condition.
Abstract: A concentrate for producing a reactive mixture which mold and mildew cannot tolerate and which removes mold and mildew from a surface without scrubbing. The primary active ingredients of the concentrate consist essentially of acetic acid, sodium metasilicate, sodium tripolyphosphate, sodium alkyl benzene sulfonate, and sodium-o-phenylphenolate. A surfactant such as polyethoxylated nonyl phenol can be included to increase the solubility of the phenolate in aqueous solution.An improved method of preparing the concentrate in a manner to prevent formation of silica gel includes adding the acetic acid last, and a three stage mixing procedure. The mold and mildew is removed by mixing the concentrate with water and bleach, and thereafter spraying the mixture onto an area to be treated.
Abstract: A mild aqueous liquid foam cleaning composition, specially adapted for cleaning the interiors of cars, train-wagons, ships, aircraft and buildings, is provided comprising a specific combination of surface-active agents, solubilizers, and an organic builder.

Additional chelating agents can be present.
Abstract: A process for the preparation of spray-dried granular detergent compositions containing an ethoxylated nonionic surfactant and a zwitterionic surfactant, wherein the degradation of the zwitterionic surfactant during processing is minimized, is disclosed. In the process, the nonionic and zwitterionic components are intimately mixed, in the absence of alkaline components, prior to their addition to an aqueous alkaline crutcher mix, which is formed into detergent granules by spray-drying.
