PROCESS FOR THE PREPARATION OF A GRANULAR DETERGENT COMPOSITION |
摘要 |
C.3173 US Granular spray-dried detergent compositions including a liquid component unsuitable for spray-drying are prepared by co-spray-drying a slurry of a porous crystal-growth-modified carbonate-based carrier salt and a detergent slurry containing detergent-active compounds, builders and other suitable ingredients, and then treating the resulting composite powder with the liquid component. The porous carrier salt is preferably the sodium carbonate/sodium sulphate double salt Burkeite, crystal-growth-modified by means of a polymeric polycarboxylate. |
