ABSTRACT:
Surfactants of a defined formula, typically prepared by reacting an alkoxylated hexitol fatty acid ester with a di- or tri-basic acid to induce a low degree of polymerization. The surfactants exhibit a higher viscosity in aqueous solution and in admixture with other conventional surfactants than the unpolymerized material.
