Multi-ionic surfactants

Abstract

Compounds, compositions and methods are provided as surfactants, fabric softening agents, corrosion inhibitors, bio-film inhibitors, biocides, and rheology modifiers. The multi-ionic surfactants are compounds having a structure corresponding to Formula 1, or a salt thereof: Wherein R1 is C1-C10 alkylene; R2 is independently hydrogen, —(CH2)x—NR20R21, or —(CH2)x—C(R10)—C(O)—X—Z; R3 and R4 are independently hydrogen, —(CH2)x—C(R10)—C(O)—X—Z, or R3 and R4 together with the nitrogen they are attached to form a substituted nitrogen-containing heterocyclyl; R5 and R6 are independently hydrogen, —(CH2)x—C(R10)—C(O)—X—Z, or R5 and R6 together with the nitrogen they are attached to form a substituted nitrogen-containing heterocyclyl; R10 is hydrogen, alkyl, aryl, or alkaryl; R11, R12, and R13 are independently C1 to C1 alkyl or alkaryl; R20 and R21 are independently hydrogen, —(CH2)x—NR20R21, —(CH2)x—C(R10)—C(O)—X—Z, or together with the nitrogen they are attached to form a substituted nitrogen-containing heterocyclyl; X is NH or O; Z is hydrogen, L1-NR11R12R13, L2-PR11R12R13, L3-COOH, L4-SO3H, L5-PO3H, or a salt thereof; L1, L2, L3, L4, and L5 are independently C1-C1 alkylene or alkenylene; n is an integer of 1 to 10; and x is an integer of 1 to 10; wherein at least one of R3 and R4, or R5 and R6 together form a substituted nitrogen-containing heterocyclyl; and wherein at least one R2 is —(CH2)x—C(R10)—C(O)—X—Z or —(CH2)x—NR20R21 wherein one of R20 or R21 is —(CH2)x—C(R10)—C(O)—X—Z.
