Abstract:
A method of boosting the detergency of a detergent, comprising admixing an amine with an average pK.sub.A of from 1 to 14 to the detergent, wherein the amine has the formula (II):(R.sup.1 R.sup.1)N--X--N(R.sup.1 R.sup.1) (II)whereineach R.sup.1 is (R.sup.2 R.sup.2)N--(CH.sub.2).sub.n --;each R.sup.2 is hydrogen or (R.sup.3 R.sup.3)N--(CH.sub.2).sub.n --;each R.sup.3 is hydrogen or (R.sup.4 R.sup.4)N--(CH.sub.2).sub.n --;each R.sup.4 is hydrogen or (R.sup.5 R.sup.5)N--(CH.sub.2).sub.n --;each R.sup.5 is hydrogen or (R.sup.6 R.sup.6)N--(CH.sub.2).sub.n --;each R.sup.6 is hydrogen;n has a value of 2, 3 or 4, andX is a radical selected from the group consisting of ##STR2##--(CH.sub.2).sub.n --, wherein n is an integer value of 2-20, and --(CH.sub.2).sub.3 --NR.sup.11 --(CH.sub.2).sub.3 --;Y is oxygen, CR.sup.7 R.sup.9 C.dbd.O or SO.sub.2 ;R.sup.7, R.sup.8, R.sup.9 and R.sup.10 are, independently of one another, hydrogen or C.sub.1-6 -alkyl, and R.sup.11 is C.sub.1-20 -alkyl, C.sub.2-20 -dialkylamino-C.sub.2-10 -alkyl,C.sub.1-10 -alkoxy-C.sub.2-10 -alkyl, C.sub.2-20 -hydroxyalkyl, or C.sub.7-20 -aralkyl, or two radicals R.sup.11 together form an alkylene chain which is uninterrupted or interrupted by nitrogen or oxygen, or polyisobutylene from with 1 to 100 isobutylene units.
