A solid antimicrobial composition of a halogenated amide such as 2,2-dibromo-3-nitrilopropionamide and a suitable hydrophilic polymer such as hydroxypropyl methyl cellulose with the optional presence of a compression agent and a mold release agent. The invention is also directed to a method for biological control in an aqueous industrial system by contacting the system with the antimicrobial composition.

A solid antimicrobial composition consisting essentially of: (a) about 1 to about 90 percent by weight of a halogenated amide antimicrobial compound of the formula [Figure] wherein X is hydrogen, halogen of a cyano radical; each R group is independently hydrogen, a monovalent saturated hydrocarbon radical or an inertly substituted monovalent saturated hydrocarbon radical or the two R groups are, jointly, a divalent saturated hydrocarbon radical, or an inertly substituted divalent saturated hydrocarbon radical, which, taken with the adjacent nitrogen atom, forms a heterocyclic ring having from 4 to about 10 ring members; and R1 is a cyano radical or an amido radical having the formula: [Figure] wherein R2 has the same meaning as R; (b) about 10 to about 80 percent by weight of a suitable hydrophilic polymer selected from the group consisting of a natural water soluble cellulosic polymer, a synthetic water soluble cellulosic polymer, gelatin, maltodextrin, xanthan gum, carrageenan, carboxymethyl guar, hydroxypropyl guar and carboxymethyl galactomannose; (c) about 0 to about 80 percent by weight of a compression agent; and (d) about 0 to about 10 percent by weight of a mold release agent.
