Abstract
A process for manufacturing effervescence component comprises grinding a coarse acid source to obtain an acid source whereof at least 75% has a particle size from 0.1 to 150 microns, mixing the ground acid source and the carbon dioxide source and optionally the binder and/or other actives to form a mixture, and submitting the mixture to a granulation step, preferably comprising a compaction step and/or an agglomeration step.
