Abstract
A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate that has been coated with a hydrotrope is provided. The crystalline calcium carbonate can be calcite and the hydrotrope can be xylene sulfonate. The crystalline calcium carbonate of the present invention is extremely inexpensive because it performs well even when used at large median particle sizes (e.g. less than 10 m.sup.2 /g surface areas).
