  • Compositions containing &agr;-sulfofatty acid esters and method of making the same
    Patent number: 6509310
    Abstract: Compositions and methods for a composition comprising at least one &agr;-sulfofatty acid ester in a first portion and at least one basic material in a second, different portion. After preparing the first and second portions separately, the first and second portions are joined to form a final composition. The first and second portions are joined together to form the final composition in a manner to minimize contact, thereby reducing the formation of additional di-salts, and thereby improving the properties of the composition.
