ABSTRACT:
The invention is a composition for controlling microbiological growth which comprises a combination of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane and tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione. The invention has particular utility as a composition for controlling microbiological growth in a slurry of paper machine additives such as precipitated calcium carbonate which comprises adding to said slurry a combination of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane and tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione.
The invention is also a method for controlling bacterial and fungal growth which comprises a combination of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane and tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione. The invention has particular utility as a method for controlling microbiological growth in a slurry of precipitated calcium carbonate which comprises adding to said slurry a combination of 1-(3-chloroallyl)-3,5,7-triaza-1-azoniaadamantane and tetrahydro-3,5-dimethyl-2H-1,3,5-thiadiazine-2-thione. A preferred weight ratio of adamantane to thione is from about 10:1 to about 1:10.
