ABSTRACT:
This invention relates to methods and compositions for obtaining synergistic anti-microbial (biocidal) activity using a combination of 2-bromo-2-(bromomethyl)-glutaronitrile and 2-bromo-2-nitro-propane-1,3-diol. The methods and compositions of the invention are very effective in preventing microbial spoilage of latex carpet backing compounds and in paper and pulp preparation, particularly with respect to latex paper coatings. Compositions containing the active ingredients in ratios of from 0.0015 parts 2-bromo-2-(bromomethyl)-glutaronitrile to 1 part 2-bromo-2-nitro-propane-1,3-diol to 40 parts 2-bromo-2-(bromomethyl)-glutaronitrile to 1 part 2-bromo-2-nitro-propane-1,3-diol.
