Abstract

A process for producing high density detergent compositions is provided. The process is a continuous process during which high density detergent agglomerates are produced by feeding a surfactant paste and dry starting detergent material into a mixer/densifier having a centrally positioned rotating shaft which experiences minimal vibration via the use of tuned dampers mounted on the shaft. The process produces a free flowing, high density detergent composition which can be commercially sold as a low dosage or "compact" detergent composition.
