Abstract (en)
The granules comprised of 40 to 80 % by weight of sodium tripolyphosphate, 20 to 70 % by weight of sodium sulphate, and 5 to 40 % by weight of sodium carbonate. Said granules have a total fluidity and mobility (free-flowing), an apparent density between 600 and 1,000 g/L, a particle size smaller than 1,500 mu m, a chemically bound water content between 0.2 % and 10 % by weight, an non-bound free water content smaller than 1 % by weight, and an absorptivity of non-ionic surfactants of at least 20 %. The granules can be obtained by a hydration/agglomeration process with a liquid ligand. The granules are appropriate as raw material in the formulation of compact detergent compositions by atomization or by dry mixing and/or agglomeration.
