Processes for producing solid surfactant compositions with decreased dissolution rates

摘要

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