ABSTRACT:
Anhydrous sodium metasilicate is stabilized against attrition or "dusting" in detergent and other use, by formulating same with such amount of an additive, e.g., a hydrate, that will transfer water content to the anhydrous metasilicate, at a temperature less than the fusion temperature of sodium metasilicate pentahydrate and as will convert from about 1% to 20% by weight of said anhydrous metasilicate into its pentahydrate form.
