Embodiment I

[0142]Ethoxylation of polyethyleneimine with an average molecular weight of 1200 Polyethyleneimine MW 1200 (Polysciences, 65.6 g, 0.055 mole) was added to a 250 ml 3-neck round bottom flask containing gram Leysen cap, thermometer connected to a temperature controller (Therm-O-Watch™, I2R), purge tube, and mechanical stirrer. Under an argon atmosphere, ethylene oxide gas (liquid carbide) was added through the purge tube at about 140°C while stirring very rapidly until a weight gain of 16.8 g (equivalent to 0.25 ethoxy units) was obtained. A portion of 25 g of the yellow gel-like substance was retained. Ethylene oxide was added to the remainder as described above. Until a weight gain of 11.7 g (corresponding to a total of 0.5 ethoxy units) is obtained. A portion of 25 g of the yellow gel-like substance was retained. Ethylene oxide was added to the remainder as above until a weight gain of 8.3 g (equivalent to a total of 0.78 ethoxy units) was obtained. A portion of 25 g of t...

Embodiment II

[0144] Ethoxylation of Polyethyleneimine with Average Molecular Weight 1800 Polyethyleneimine MW 1800 (Polysciences, 50.0 g, 0.028 mole) was added to a 250 ml three-neck round bottom flask containing Claisen Top cover, with thermostat (Therm-O-Watch TM , I 2 R) Connected thermometer, purge line, and mechanical stirrer. Under an argon atmosphere, ethylene oxide gas (liquid carbide) was added through the purge tube at about 140° C. while stirring very rapidly until a weight gain of 52 g (equivalent to 1.2 ethoxy units) was obtained. 50 g of the yellow gel-like substance was kept. Potassium hydroxide pellets (Baker, 0.30 g, 0.0053 mol) were added to the remainder. After the potassium hydroxide had dissolved, ethylene oxide was added as above until a weight gain of 60 g (equivalent to a total of 4.2 ethoxy units) was obtained. 53 g of the brown viscous liquid remained. Ethylene oxide was added to the remainder as above until a weight gain of 35.9 g (corresponding to a total o...

Embodiment III

[0145] Benzylation of poly(ethyleneimine) MW 1800 to 10 Mole % with respect to nitrogen atoms, and subsequent ethoxylation A 100 ml three-neck round bottom flask was equipped with a magnetic stirring bar, condenser, thermometer, Temperature controller (Therm-O-Watch TM , I 2 R) and addition funnel. To the reaction flask was added poly(ethyleneimine) MW 1800 (Polysciences Inc. 20.0 g, 0.011 moles). Benzyl chloride (Aldrich 5.9 g, 0.047 moles) was added to the addition funnel. It is sufficient to react with 10 mol% of available nitrogen in the poly(ethyleneimine). The reaction flask was now heated to 100°C under an argon atmosphere, at which temperature benzyl chloride was added dropwise at a rate of 1 drop every 3 seconds. A temperature rise of about 10°C was noted during the dropwise addition. After the addition of benzyl chloride was complete, the reaction was continuously heated at 100° C. for 5 hours under an argon atmosphere. After cooling briefly, the orange product...

Abstract

Cleaning and soil dispersing compositions comprising ethoxylated / propoxylated polyalkyleneamine polymers are provided. Thus, detergent compositions which comprise ethoxylated / propoxylated polyalkyleneamine polymers, such as poly(ethyleneimine) with a degree of ethoxylation of 1.0, provide soil dispersing performance in the wash liquor and whitening and / or cleaning benefits to fabrics, hard-surfaces, or dishware.

Description

technical field [0001] This invention relates to soil cleaning and suspending compositions which utilize alkoxylated, especially ethoxylated and / or propoxylated polyalkyleneamine polymers to enhance soil dispersing properties. Fabric washing, dishwashing and hard surface cleaning compositions having improved soil dispersing properties are provided. Background of the invention [0002] Detergent formulators are faced with the task of designing products that remove a broad spectrum of soils and stains from fabrics. Various types of chemical and biochemical soils and stains vary from polar to nonpolar, polar such as proteinaceous, clay and inorganic, nonpolar such as soot, carbon black, hydrocarbons By-products of incomplete combustion and organic fouling. Detergent compositions are further complicated as formulators attempt to provide products that accommodate all types of products. [0003] Formulators have had great success in developing traditional...
