Abstract: Disclosed are precipitated silicas obtainable by acid precipitation of aqueous silicate solutions while maintaining a constant alkali number of at least 1, having good sorption characteristics for polar compounds. The precipitated silicas are useful as carrier material for choline chloride for example, and feed additives, chemical intermediates and in laundry detergent.
