Abstract
A process for continuously preparing high density detergent composition is provided. The process comprises the steps of: (a) continuously charging a detergent surfactant paste and dry starting detergent material into a mixer/densifier for densification and build-up to obtain agglomerates; (b) feeding the agglomerates into a conditioning apparatus for improving the flow properties of the agglomerates and for separating the agglomerates into a first agglomerate mixture and a second agglomerate mixture; (d) recycling the first agglomerate mixture into the mixer/densifier for further agglomeration; (e) admixing adjunct detergent ingredients to the second agglomerate mixture so as to form the high density detergent composition.
