Abstract: 

Disclosed are processes for sterilization of cyanoacrylate adhesive compositions, the compositions, comprising 2-cyanoacrylate ester monomers, so produced and a method for assaying the effectiveness of the sterilization process. The process comprises heating the adhesive composition to from about 70° C. to about 140° C. for an effective amount of time. The effectiveness of the process can be assayed by disposing bacterial spores in the cyanoacrylate monomer, exposing the composition to a dry heat sterilization process, transferring the cyanoacrylate composition to a sterile aldose solution, transferring and exposing the sample to a nutrient medium which supports germination and growth of viable spores, incubating the samples, and determining the presence or absence of growth.
