Abstract
Novel, biodegradable cationic surface-active agents are disclosed. These compounds, when used in laundry detergent compositions together with selected nonionic surfactants, provide excellent removal of particulate and greasy/oily soils, as well as providing fabric softening, static control, and dye transfer inhibition benefits to the laundered fabrics.
Claims50
A compound having the formula ##STR40## wherein each R.sup.1 is C.sub.1 to C.sub.4 alkyl or hydroxyalkyl;
- each R.sup.2 is either hydrogen or C.sub.1 to C.sub.3 alkyl;
- R.sup.3 is C.sub.4 to C.sub.30 straight or branched chain alkyl or alkenyl;
- R.sup.4 is C.sub.1 to C.sub.10 alkylene or alkenylene;
- n is from 2 to 4;
- y is from 1 to 20;
- a is 0 or 1, and t is 0 to 1, but t must be 1 when a is 1;
- m is from 1 to 5;
- Z.sup.2 is selected from the group consisting of ##STR41## Z.sup.1 is selected from the group consisting of ##STR42## said selections being made so that ##STR43## is an alkyl or alkenyl group which can be interrupted by only structures selected from the group consisting of:
- ##STR44## and wherein at least one of said Z.sup.1 or Z.sup.2 groups is selected from the group consisting of ester, reverse ester, amide, and reverse amide;
- and X is an anion which makes the surfactant at least water-dispersible.
