Abstract
Phosphate-free calcium carbonate-contg. granules are made from (a) submicron calcium carbonate particles with a large effective surface and a low degree of agglomeration and (b) an alkali carbonate, bicarbonate and/or sesquicarbinate in a wt. ratio (b): (a) of 1:2 to 75:1. The granules are useful as additives to washing powders which dissolve rapidly and which act as crystallisation grafts to ppte. soluble Ca salts from the bath.
