<p>The granules are 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), and apparent density between 600 and 1000 g/L, a particule size smaller than 1500 νm, a chemically bound water content between 0.2 % and 10 % by weight, a 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.</p> |
