Abstract:
A method of boosting detergency of a detergent, which comprises:(a) admixing one or more amines with an average pK.sub.A of from 1 to 14 to the detergent, containing at least one surfactant, wherein the one or more amines have the formula (I):RR'N-(-(CR.sup.1 R.sup.2).sub.x -NR.sup.3 -).sub.a -((CR.sup.4 R.sup.5).sub.y -NR.sup.6 -).sub.b -R"" (I)wherein R, R', R"", R.sup.1, R.sup.2, R.sup.4, R.sup.5, are, independently of each other, linear or branched-chain C.sub.1-20 alkyl, (alkyl)carbonyl or alkylamino, C.sub.2-20 alkenyl or C.sub.6-20 aryl, aryloxy, hydroxyaryl, arylcarboxy or arylamino;R.sup.3 and R.sup.6 are, independently of each other, hydrogen, linear or branched-chain C.sub.1-20 alkyl, C.sub.6-20 aryl, which optionally substituted, or ((CR.sup.7 R.sup.8).sub.z -NR.sup.9).sub.c -R.sup.10, wherein R.sup.7, R.sup.8, R.sup.9 and R.sup.10 are, independently of each other, as defined for R, R', R"", R.sup.1, R.sup.2, R.sup.4, R.sup.5 ; andx, y and z have independently of each other, a value of 2, 3 or 4; and a, b and c have, independently of each other, an integral value value of 0-300, with the exception of mono- and diamines, and wherein polyethyleneimines are optionally rendered hydrophobic by partial modification with benzoic acid; andb) contacting a fabric with the detergent in an amount and for a time sufficient to remove soil from the fabric.
