- wherein R2 is selected from the group consisting of hydrogen, C1-C24 alkyl and C2-C24 alkenyl-CH2-, each R3 independently is a straight chain or branched C2-C4 alkylene, x is a number from 1 to 50 inclusive and y is a number from 0 to 50 inclusive,
- or the chemical interaction products thereof.
A pesticide formulation comprising at least one pesticide and at least one aromatic acid neutralized with at least one ethoxylated amine wherein said aromatic acid is of the formula (2):
- 33
- wherein each R1 independently is a straight chain or branched C2-C4 alkylene, n is a number from 1 to 50 inclusive,

A compound of Formula (1):
- (H-B)+A− (1)
- wherein A− is the conjugate base of the acid H-A, wherein H-A is an alkoxylated tristyrylphenol hemi-sulfate ester;
- and the (H-B)+ is the conjugate acid of the base B, wherein B is an alkoxylated amine.
