Ruptureable, dual reagent mono-capsules are disclosed that have a core composition, which includes a first reagent, encapsulated within a polymer wall, and a shell connected to an exterior surface of the polymer wall by a surfactant. The shell is made from a second reagent that is chemically bonded to the surfactant by a chemical electrostatic interaction. Upon rupture of the polymer wall of the mono-capsule, the first reagent and the second reagent chemically react with one another to form a reaction product.
