Publication number: 20110046240Abstract: The present invention relates to a method for forming a calcium-based carrier particle consisting of the calcium-based material, an active, with or without a surface modification, a stabilizing agent, and the related composition. The calcium-based particle is illustrated by the general formula Cax(PO4)y(OH)zR and may also include a silica or silica oxide substituent. R is an active or actives such as an organic or inorganic molecule that includes markers, amines, thiols, epoxies, organosilicones, organosilanes, sulfates, and water soluble agents and, as needed, a surface modification, S, which may be either organic or inorganic. A stabilizing agent may be necessary to maintain dispersion of the particles in aqueous media. Examples of a surface modifying material and stabilizing agents are inorganic salts of aluminum and boron or organic materials such as organosilanes or low molecular weight polymers.Type: ApplicationFiled: August 24, 2009Publication date: February 24, 2011Inventors: Timothy S.
