A suspension composition and a method of preparing the suspension composition are provided herein. The suspension composition comprises a continuous aqueous phase (a), a substance (b) that is capable of transport through the aqueous phase thereby resulting in Ostwald ripening of the substance in the suspension composition, and a dispersing agent (c). The dispersing agent comprises the reaction product of at least one monomer (i) and at least one additional monomer (ii). The at least one monomer (ii) is represented by the general formula (I): wherein R is hydrogen, an alky] group or an aryl group R1 is an alkyl group having at least 2 carbon atoms k is 2 to 4 and n is at least about 10. The at least one additional monomer (ii) has unsaturated functionality and contains at least one carbonyl group. The dispersing agent is present in the suspension composition in an amount that is sufficient to limit Ostwald ripening of the substance (b) in the suspension composition.
