Composition

Abstract

A composition is disclosed comprising an anionically modified alkyl and/or alkenyl phenol polyoxyalkylene ether represented by the formula (I) wherein R1 is a linear or branched, alkyl or alkenyl group having 11 to 21 carbon atoms; each R2 is an oxyalkylene group having 2 to 4 carbon atoms; m is an integer from 1 to 50; E is a group comprising one or more of sulfate, phosphate, carboxylate, sulfonate, sulfosuccinate, sulfoacetate, sarcosinate and phosphonate; M is a solubilizing cation selected from sodium, potassium, ammonium, mono-, di-, tri-alkanolamine and mixtures thereof; and a phosphate sequestrant; wherein the phosphate sequestrant comprises 1-hydroxyethylidene-1,1-diphosphnic acid (HEDP), diethylenetriaminepenta(methlenephosphonic acid) (DTPMP), hexamethylenediaminetetra(methylenephosphonic acid) (HDTMP), aminotris(methylenephosphonic acid) (ATMP), ethylenediaminetetra(methylenephosphonic acid) (EDTMP), tetramethylenediaminetctra(methylenephosphonic acid) (TDTMP), phosphonobutanetricarboxylic acid (PBTC), or mixtures thereof, preferably 1-hydroxyethylidene-1,1-diphosphnic acid (HEDP), diethylenetriaminepenta(methylenephosphonic acid)(DTPMP) or mixtures thereof, preferably diethylenetiaminepenta(methylenephosphonic acid) (DTPMP).
