Abstract
The present invention provides DASC compositions, which upon introduction into aqueous solutions, form stable, non-gritty suspensions. The present invention also provides stable, non-gritty suspensions comprising the DASC compositions of the present invention admixed in aqueous solutions. In addition, the present invention provides processes for preparing the suspensions which comprise admixing the DASC compositions of the present invention with aqueous solutions. Finally, the present invention provides processes for preparing the DASC compositions of the present invention.
Claims16
A process for preparing a dihydroxy aluminum sodium carbonate (DASC)/polyol suspension comprising the steps of:
- (i) synthesizing DASC;
- (ii) isolating the synthesized DASC to provide isolated, undried DASC;
- and (iii) mixing the isolated, undried DASC with water and at least one polyol selected from the group consisting of sorbitol, glycerin, mannitol, maltodextrin and fructose to form an aqueous DASC/polyol suspension.
