PROCESS FOR MAKING A LOW DENSITY DETERGENT COMPOSITION BY AGGLOMERATION FOLLOWED BY DIELECTRIC HEATING

摘要

A process is provided which produces a low density (below about 600 g/l) detergent composition directly from starting detergent ingredients. The process employs dielectric heating means, such as a microwave (MW) dryer or a Radio Frequency (RF) dryer, to "puff" agglomerates formed by agglomerating a surfactant paste or acid precursor thereof and dry detergent materials. The process does not require the use of conventional spray drying towers, and therefore, is more efficient, economical and flexible with regard to the variety of detergent compositions that can be produced in the process.
