Patent number: 5552084Abstract: This invention provides a process for producing a particulate potassium bicarbonate composition which maintains its free-flow properties when stored under ambient temperature and relative humidity conditions. In the process, particulate potassium bicarbonate is blended with fine grain alkaline earth metal oxide, and the oxide is microdispersed on the surface of the particles. The oxide reacts with moisture and carbon dioxide to form an adherent physically-bonded coating of alkaline earth metal carbonate on the surface of the potassium bicarbonate particles. The altered particle surface prevents agglomeration of the potassium bicarbonate particles.Type: GrantFiled: November 16, 1995Date of Patent: September 3, 1996Assignee: Church & Dwight Co., Inc.Inventors: M. Stephen Lajoie, Robin C. Sargent
