ABSTRACT:
A dispersion including anionic softeners and a process for producing compositions of anionic softeners is provided and obtainable by (a) reacting partial glycerides with maleic anhydride at a temperature above 53° C., wherein maleic anhydride is used in stoichiometric or below stoichiometric quantities to form a reaction product; and, (b) reacting the reaction product with an aqueous solution of sodium sulphite, wherein a quantity of water is selected to form a final product in the form of a 5 to 50 wt % aqueous solution. Powder compositions of anionic softeners may be obtained by drying the final product.
