    Patent number: 4240918
    Abstract: Novel anti-soiling and anti-redeposition adjuvants for detergent compositions include at least one polymer A, said polymer itself having anti-soiling and anti-redeposition properties, at least one solubilizing and dispersing agent B for said polymer A, and at least one water repellent C for said agent B.
    Type: Grant
    Filed: November 2, 1978
    Date of Patent: December 23, 1980
    Assignee: Rhone-Poulenc Industries

  • Hydrophilic polyurethanes and their application as soil-release, anti-soil redeposition, and anti-static agents for textile substrates
    Patent number: 4201824
    Abstract: Novel linear hydrophilic polyurethane polymers are presented. The polymers provide outstanding soil-release, anti-soil redeposition and anti-static properties when applied to natural and synthetic textile substrates, especially textile substrates containing polyester fibers. These polyurethanes are particularly useful in detergent compositions.

  • Hydrophilic polyurethanes and textiles treated therewith
    Patent number: 4068035
    Abstract: A hydrophilic polyurethane composition comprising a reaction product of:1. 10 to 45 weight percent of an organic diisocyanate and,2. 35 to 89 weight percent of a compound containing one or two active hydrogen atoms selected from:A. 75 to 100 weight percent of a compound of the general formula:R--(O--C.sub.x H.sub.x).sub.n -OHwhereinR is hydrogen or a hydrocarbon radical containing from 1 to 20 carbon atoms;X is a number from 2 to 4;n is a number to indicate that the molecular weight is between 300 and 10,000; and,B. 0 to 25 weight percent of a diol and,3. 1 to 25 weight percent of a nitrogen-containing compound of the general formula: ##STR1## wherein R' is an alkyl radical containing from 1 to 5 carbon atoms;X.sub.1 and X.sub.2 are hydroxyalkyl or amino alkyl radicals with the proviso that the overall ratio of NCO/active H is from about 0.7 to about 1.
