Embodiment 1

[0143] Under the trade name Baxxodur 2.5 g polyetheramine(2-aminomethylethyl)-omega-(2-aminomethylethoxy)-poly(oxo(methyl-1,2-ethanediyl) sold by (BASF) ) were added to 10.0 g of an aqueous solution of a 50% by weight copolymer of acrylic acid and maleic acid at room temperature. The copolymer of acrylic acid and maleic acid has an average molecular weight Mn of about 70,000 g / mol (measured by gel permeation chromatography, calibrated with polystyrene sulfonic acid) and a molar ratio of acrylic acid to maleic acid of 4:1. The temperature was increased to 50°C. The mixture was stirred for an additional 1 h without external heating. Water was removed in vacuo (0.7 mbar). After trituration, 4.5 g of white, odorless crystals are obtained. pH of a 10% solution in water: 6.

Embodiment 2

[0145] Under the trade name Baxxodur 25.0 g of polyetheramine(2-aminomethylethyl)-omega-(2-aminomethylethoxy)-poly(oxo(methyl-1,2-ethanediyl) sold by (BASF) ) were added to 100.0 g of a 50% by weight aqueous solution of acrylic acid homopolymer in sodium salt at room temperature. The sodium salt of the homopolymer of acrylic acid has a molecular weight of about 4,000 g / mol (measured by gel permeation chromatography, calibrated with polystyrenesulfonic acid). The temperature was raised to 41 °C. The mixture was stirred for an additional 2 hours at 60°C. Water was removed in vacuo (0.7 mbar). After grinding, 70.0 g of pale yellow crystals were obtained. A 10% solution in water has a pH of 6.

Embodiment 3

[0147] 62.5 g of polyether derived from 2-butyl-2-ethyl-1,3-propanediol, alkoxylated with 2.0 mol of propylene oxide per OH, and aminated (amine value 278.2 mg KOH / g) The amine was added to 250.0 g of an aqueous solution of a 50% by weight copolymer of acrylic acid and maleic acid at room temperature. The copolymer of acrylic acid and maleic acid has a molecular weight of about 70,000 g / mol (measured by gel permeation chromatography, calibrated with polystyrene sulfonic acid) and a molar ratio of acrylic acid to maleic acid of 4:1. The temperature was increased to 50 °C. The mixture was stirred at 60 °C for an additional 2 hours. Water was removed in vacuo (0.7 mbar). After grinding, 85.0 g of white, odorless crystals are obtained. A 10% solution in water has a pH of 6, water content: 0.9%.

Abstract

The present invention relates generally to detergent compositions and, more specifically, to detergent compositions containing salts of polyetheramines and polymeric acid, particularly salts of polyetheramines and polycarboxylic acid, which are suitable for removal of stains from soiled materials.

Description

[0001] field of invention [0002] The present invention relates generally to detergent compositions, and more particularly to detergent compositions comprising salts of polyetheramines and polymeric acids, especially salts of polyetheramines and polymeric acids suitable for removing stains from soiled materials. Background technique [0003] Due to the increasing popularity of easy-care fabrics made of synthetic fibers, increasing energy costs and growing ecological concerns for detergent users, the once-popular warm and hot water washing has now given way to washing in cold water (30°C). and below). Many commercially available laundry detergents are even advertised as being suitable for washing fabrics at 15°C or even 9°C. To achieve satisfactory washing results at such low temperatures, ie results comparable to those obtained with hot water washing, the demand for low temperature detergents is especially high. [0004] It is known to include certain additives in detergent...
