Title of Invention

SURFACTANT SYSTEM CONTAINING PHOSPHATE ESTER AND ALKOXYLATED LIGNO SULFONATE

Abstract

The present invention relates to a surfactant system comprising: I a) at least one alkoxylated polyarylphenol phosphate ester of the formula (1): wherein R<sub>1</sub> independently is a straight chain or branched C<sub>2</sub>-C<sub>4</sub> alkylene, R<sub>2</sub> is phenyl, aryl or alkylaryl, wherein the phenyl nucleus in R<sub>2</sub> is unsubstituted or substituted by one to three groups selected from the group consisting of C<sub>1</sub>-<sub>4</sub> alkyl or C<sub>1</sub>-C<sub>4</sub> alkoxy, and R<sub>3</sub> and ~ are independently selected from the group consisting of hydrogen, sodium, potassium, and m, is 2 or 3, and n is a number from 1 to 150 inclusive, and b) a (C<sub>2</sub>-C<sub>4</sub>) alkoxylated lignosulfonate salt.
