Abstract: Solutions comprising at least one polyamino disuccinic acid and one or more polyamino monosuccinic acids are useful in gas conditioning (preferably as the iron chelate). The copper chelates are also useful in electroless copper plating. Another aspect of the invention includes the use of the aminosuccinic acid mixtures in laundry detergent compositions.
Abstract: A laundry detergency boosting polymer blend additive is made up of:a) a graft copolymer of polyalkylene oxide with vinyl ester, the graft copolymer having a molecular weight within the range of about 5,000 to 50,000; andb) at least one polycarboxylate selected from the group consisting of acrylic/maleic acid copolymers having a molecular weight within the range of about 1,000 to 100,000, and polyacrylic acid having a molecular weight of from about 1,000 to 100,000. The polymer blend additive is effective in water with an ion hardness in the range of about 50 to 500 ppm. The detergency boosting performance of the polymer blend additive is maintained or increased as the concentration of the hardness ions in water is increased.

Abstract: Low cost, highly aqueous, thickened heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of surfactant materials, a formate-based viscosity-enhancing agent, a selected type of thickening perfume and relatively large amounts of water. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.

Abstract: This invention relates to a cleaning composition comprising a water insoluble organic compound, an alkyl glucoside surfactant, an abrasive, a sulfonate surfactant, an ethoxylated alkyl ether sulfate surfactant, a polymeric thickener, a cosurfactant and water.
Abstract: Low cost, effective aqueous heavy duty liquid laundry detergent compositions are provided. Such compositions contain relatively low levels of an anionic/nonionic-based suffactant system along with a protease-containing enzyme component, a low-cost viscosity-enhancing agent and relativly large amounts of water. The anionic component of the surfactant system comprises a combination of alkyl sulfate and alkyl ether sulfate. The nonionic component of the suffactant system comprises fatty alcohol ethoxylates. Only minimal amounts of other detergent composition adjuvants are permitted in such compositions.

Abstract: A method of making a hard surface abrasive scouring cleanser, in steps comprising making an aqueous solution of nonionic surfactant and pH adjusting agent; making a slurry of water and a calcium carbonate abrasive, and allowing the slurry to degas; adding the slurry of to the aqueous solution slowly with gentle mixing and allowing the resultant mixture to degas; and adding a quantity of cross-linked polyacrylate and any other adjunct ingredients. The cleanser has no significant syneresis, undue viscosity or yield stress increase, stably suspends abrasives, and has excellent rinsing characteristics.

Abstract: A detergent composition is disclosed. The composition comprises polymer particles having an average particle size of 50-500 .mu.m in 5% by weight sodium chloride aqueous solution and a modulus of elasticity of 1.times.10.sup.3 -5.times.10.sup.5 dyne/cm.sup.2 in said sodium chloride aqueous solution. It exhibits a superior physical or mechanical washing performance, and gives remarkably reduced irritation and minimal damage to the object being washed. When a germicide is incorporated in addition to the polymer particles, its sterilization effect is greatly enhanced.
Abstract: Physically stable, non-scratching hard surface cleaning compositions having shear thickening properties are provided and include an alkali metal silicate, an inorganic or organic compound containing an alkali metal cation or an organic compound containing at least one hydroxyl group and water.
