Composition and method for treating and/or preventing biological contamination using a biocide composition comprising at least one quaternary ammonium compound and urea. The method includes drying urea, and thereafter combining at least one quaternary ammonium compound and urea and may produce a potent biocide composition that is stable and able to chemically treat biological contamination in a variety of difficult to reach locations. Uses of the composition are also described.

1. A method of making a biocide composition comprising: drying urea, and drying at least three quats by heating; and thereafter,combining the at least three quats, a chelator, and the urea to form a chelated quat/urea biocide composition, comprising spraying the at least three quats onto the urea,wherein the at least three quats are independently represented by the formula wherein R for the at least three quats is independently an alkyl chain with a length of 8 to 18 carbons;wherein the drying urea comprises heating the urea to a temperature in a range from about 90 to about 110° C. 2. The method of claim 1, wherein the step of heating the at least three quats comprises gradually heating the at least three quats to a temperature in a range from about 30 to about 40° C. 3. The method of claim 1, wherein the step of heating the at least three quats comprises heating the at least three quats in the presence of a solvent. 4. The method of claim 1, further comprising granulating the biocide composition. 5. The method of claim 1, further comprising adding organic solvent to the at least three quats before the step of heating the at least three quats. 6. The method of claim 1, wherein the at least three quats and urea are present in the chelated quat/urea biocide composition in amounts based on a weight ratio of quats to urea from about 10:90 to about 90:10, or from about 20:80 to about 60:40, or from about 30:70 to about 50:50, or a weight ratio of about 40:60. 7. The method of claim 1, wherein about 50 to about 100% by weight of the three or more quaternary ammonium compounds present in the chelated quat/urea biocide composition comprises an alkyl chain length in the range of about 12 carbons to about 18 carbons. 8. The method of claim 1, wherein about 50 to about 100% by weight of the three or more quaternary ammonium compounds present in the chelated quat/urea biocide composition comprises an alkyl chain length in the range of about 14 carbons to about 16 carbons.
