PROCESSES FOR PRODUCING SOLID SURFACTANT COMPOSITIONS WITH ENHANCED DISSOLUTION RATES

摘要

The processes involve the incorporation in the solid surfactant of particles of citric acid. In each of the processes melted surfactant is mixed with solid citric acid particles, and the mixture is then solidified. In each of the processes, the citric acid particles comprise from about 1 to 8 weight percent of the combined weight of surfactant and citric acid. The various processes may additionally involve extrusion, spray-coating, or spraying combined with blending.
