A comparison of compacting and caking behaviour of carbonate-based washing powders

Two types of sodium carbonate powder produced by spray drying (SD) and dry neutralisation (DN) were studied for their compaction properties using a uniaxial compression tester. Dry neutralised sodium carbonate showed a greater resistance to compression and also produced a weaker compact when compressed to 100kPa. Differential Scanning Calorimetry (DSC) showed that both types of powder were predominantly amorphous in nature. Moisture sorption measurements showed that both powders behaved in a similar way below 50% RH. However, dry neutralised sodium carbonate had a high moisture affinity above this RH. On examining the particle structures using Scanning Electron Microscopy (SEM), the most likely explanation for the increased tendency of spray dried sodium carbonate to form strong compacts was the hollow particle structure.
