1. A compound having the formula ##STR40## wherein each R1 is C1 to C4 alkyl or hydroxyalkyl;
- each R2 is either hydrogen or C1 to C3 alkyl;
R3 is C4 to C30 straight or branched chain alkyl or alkenyl;
R4 is C1 to C10 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;
Z2 is selected from the group consisting of ##STR41## Z1 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 Z1 or Z2 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.

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.
