Abstract (en)
[origin: WO9323007A1] The compatibility of silicas with therapeutic agents in oral care compositions is improved by dehydroxylating the silica by a) thermal treatment and/or b) chemical reaction with a dehydroxylation agent selected from the group consisting of alcohols, silanes, and organosilanes. The invention provides especially beneficial improvement in compatibility between silica and non-fluoride therapeutic agents used in dentifrice and other oral care compositions.
