    • The present invention relates to hydrophobically modified polyamines and laundry detergent compositions which comprise said polyamines, said compositions comprising: A) from about 0.01%, preferably from about 0.1%, more preferably from about 1%, most preferably from about 3% to about 50%, preferably to about 20%, more preferably to about 10%, most preferably to about 7% by weight, of a hydrophobically modified polyamine having the formula: wherein R is C6-C20 linear or branched alkylene, and mixtures thereof; R1 is an alkyleneoxy unit having the formula: —(R2O)x—R3 wherein R2 is C2-C4 linear or branched alkylene, and mixtures thereof; R3 is hydrogen, C1-C22 alkyl, C7-C22 alkylenearyl, and mixtures thereof; x is from about 15 to about 30; at least one Q moiety is a hydrophobic quaternizing unit selected from the group consisting of C8-C30 substituted or unsubstituted linear or branched alkyl, C6-C30 substituted or unsubstituted cycloalkyl, C7-C30 substituted or unsubstituted alkylenearyl, and mixtures thereof, and the remaining Q moieties are selected from the group consisting of lone pairs of electrons on the unreacted nitrogens, hydrogen, C1-C30 substituted or unsubstituted linear or branched alkyl, C3-C30 substituted or unsubstituted cycloalkyl, C7-C30 substituted or unsubstituted alkylenearyl, and mixtures thereof; X is an anion present in sufficient amount to provide electronic neutrality; n is from 0 to 3; B) from about 0.01% by weight, of a surfactant system comprising one or more surfactants selected from: i) from 0% to 100% by weight, of one or more anionic surfactants; ii) from 0% to 100% by weight, of one or more nonionic surfactants; iii) optionally from 0.1% to about 80% by weight, of one or more cationic surfactants; iv) optionally from 0.1% to about 80% by weight, of one or more zwitterionic surfactants; v) optionally from 0.1% to about 80% by weight, of one or more ampholytic surfactants; or vi) mixtures thereof; C) the balance carriers and adjunct ingredients.
