A substantially anhydrous and homogeneous composition consisting essentially of a dithionite selected from sodium, potassium and calcium dithionites and from 0.1 to 10% by weight in said composition of an unsaturated carboxylic acid or an anhydride thereof. Preferred acids are aryloxy alkanoic acids of formula ArORCO2H wherein Ar is a substituted or unsubstituted aryl group and R is a substituted or unsubstituted methylene or polymethylene group. Most preferred is phenoxyacetic acid. Such acids may exhibit enhanced effectiveness over previous stabilizers. |
