Abstract
Detergent compositions which comprise from about 0.05 to about 95% by weight of a water-soluble ethoxylated amine having clay soil removal/anti-redeposition properties. These compounds are selected from ethoxylated monoamines, ethoxylated diamines, ethoxylated polyamines, ethoxylated amine polymers and mixtures thereof. In addition to the ethoxylated amines, the detergent compositions further comprise from about 1 to about 75% by weight of a nonionic, anionic, ampholytic, zwitterionic or cationic detergent surfactant, or mixture thereof. In addition to these detergent surfactants, the detergent composition can optionally comprise from 0 to about 80% by weight of a detergent builder.
Claims25
A laundry detergent composition, which comprises:

- (2) ethoxylated diamines having the formula:
- ##STR22## (3) ethoxylated polyamines having the formula:
- ##STR23## (4) ethoxylated amine polymers having the general formula:
- ##STR24## and (5) mixtures thereof;
- wherein A.sup.1 is ##STR25## R is H or C.sub.1 -C.sub.4 alkyl or hydroxyalkyl;
- R.sup.1 is C.sub.2 -C.sub.12 alkylene, hydroxyalkylene, alkenylene, arylene or alkarylene, or a C.sub.2 -C.sub.3 oxyalkylene moiety having from 2 to about 20 oxyalkylene units provided that no O--N bonds are formed;
- each R.sup.2 is C.sub.1 -C.sub.4 alkyl or hydroxyalkyl, the moiety --L--X, or two R.sup.2 together form the moiety --(CH.sub.2).sub.r --A.sup.2 --(CH.sub.2).sub. s--, wherein A.sup.2 is --O-- or --CH.sub.2 --, r is 1 or 2, s is 1 or 2, and r+s is 3 or 4;
- X is a nonionic group selected from the group consisting of H, C.sub.1 -C.sub.4 alkyl or hydroxyalkyl ester or ether groups and mixtures thereof , an anionic group selected from the group consisting of SO.sub.3.sup.- and PO.sub.3.sup.-2, or mixtures thereof;
- R.sup.3 is a substituted C.sub.3 -C.sub.12 alkyl, hydroxyalkyl, alkenyl, aryl, or alkaryl group having p substitution sites;
- R.sup.4 is C.sub.1 -C.sub.12 alkylene, hydroxyalkylene, alkenylene, arylene or alkarylene, or a C.sub.2 -C.sub.3 oxyalkylene moiety having from 2 to about 20 oxyalkylene units provided that no O--O or O--N bonds are formed;
- L is a hydrophilic chain which contains the polyoxyalkylene moiety --[(R.sup.5 O).sub.m (CH.sub.2 CH.sub.2 O).sub.n ]--, wherein R.sup.5 is C.sub.3 -C.sub.4 alkylene or hydroxyalkylene and m and n are numbers such that the moiety --(CH.sub.2 CH.sub.2 O).sub.n -- comprises at least about 50% by weight of said polyoxyalkylene moiety;

- for said polyamines and amine polymers, m is from 0 to about 10 and n is at least about 3;
- p is from 3 to 8;
- q is 1 or 0;
- t is 1 or 0, provided that t is 1 when q is 1;
