- wherein each R is independently selected from the group consisting of C1-C24 alkyl and C7-C24 alkylaryl, m is a number from 0 to 5, n is a number from 1 to 3, p is a number from 0 to 3, q is a number from 0 to 3, and r is a number from 0 to 4, s is a number from 1 to 3,
- wherein (H—B)+ is the cation of the formula:
- wherein R4 is selected from the group consisting of C7-C24 alkyl and C2-C24 alkenyl—CH2—, each R5 independently is a straight chain or branched C2-C4 alkylene, x is a number from 1-50 and y is a number from 0 to 50, wherein the salt compound has a pH of 4 to 6.
A product obtained by the process of neutralizing at least one aromatic sulfonic acid of formulae II or III:
- wherein each R is independently selected from the group consisting of hydrogen, C1-C24 alkyl and C7-C24 alkylaryl, m is a number from 0 to 5, n is a number from 1 to 3, p is a number from 0 to 3, q is a number from 0 to 3, and r is a number from 0 to 4, s is a number from 1 to 3,
- with at least one alkoxylated amine base of formula IV:
- wherein R4 is selected from the group consisting of C7-C24 alkyl and C2-C24 alkenyl—CH2—, each R5 independently is a straight chain or branched C2-C4 alkylene, and the average x+y is a number from 2 to 50 inclusive, wherein the product has a pH of 4 to 6.
A surfactant composition comprising a salt of:
- at least one aromatic sulfonic acid compound represented by the formulae II or III:
- wherein each R is independently selected from the group consisting of C1-C24 alkyl and C7-C24 alkylaryl, m is a number from 0 to 5, n is a number from 1 to 3, p is a number from 0 to 3, q is a number from 0 to 3, and r is a number from 0 to 4, s is a number from 1 to 3, and

- wherein R4 is selected from the group consisting of C7-C24 alkyl and C2-C24 alkenyl—CH2—, each R5 independently is a straight or branched chain C2-C4 alkylene, and the average x+y is a number from 2 to 50 inclusive, wherein the surfactant composition has a pH of 4 to 6.
A chemically integrated surfactant composition comprising at least one aromatic sulfonic acid compound represented by formula II or III:
- wherein each R is independently selected from the group consisting of C1-C24 alkyl and C7-C24 alkylaryl, m is a number from 0 to 5, n is a number from 1 to 3, p is a number from 0 to 3, q is a number from 0 to 3, and r is a number from 0 to 4, s is a number from 1 to 3,
- and at least one alkoxylated amine base represented by the formula IV:
- wherein R4 is selected from the group consisting of C7-C24 alkyl and C2-C24 alkenyl—CH2—, each R5 independently is a straight or branched chain C2-C4 alkylene, and the average x+y is a number from 2 to 50 inclusive,
- or the chemical interaction products thereof wherein the chemically integrated surfactant has a pH of 4 to 6.
A pesticide formulation comprising at least one pesticide and at least one aromatic sulfonic acid neutralized with at least one ethoxylated amine wherein said aromatic sulfonic acid is represented by the formulae (II) or (III):
- wherein each R is independently selected from the group consisting of C1-C24 alkyl and C7-C24 alkylaryl, m is a number from 0 to 5, n is a number from 1 to 3, p is a number from 0 to 3, q is a number from 0 to 3, and r is a number from 0 to 4, s is a number from 1 to 3,
- and the said alkoxylated amine is represented by the formula IV:
