Bioban™ BP-Plus Preservative may be used in the following end-use applications.

Pulp and Paper
Bioban™ BP-Plus Pres may be used for the control of slime-forming bacteria in paper mill process water and bulk pulp. It can be added into the hydropulper, machine chest or stock check. The correct dose of active ingredient for these applications is 10-250 ppm Bioban™ BP-Plus Pres in paper mill process water and 50-250 ppm Bioban™ BP-Plus Pres  in bulk pulp.

Water Treatment
Bioban™ BP-Plus Pres may be used to control slime-forming bacteria in recirculating water cooling towers, evaporative condensers, industrial process water, and air scrubber, air conditioner and humidifier systems. BIOBANᵀᴹ BP-PLUS Preservative may be dosed directly into the sump or basin at any point where there is adequate agitation to ensure dissolution. The correct dose range of active ingredient is 25-100 ppm Bioban™ BP-Plus Pres.
Absorbent Clays, Corn Cobs and Ground Wood
Bioban™ BP-Plus Pres may be used in absorbent clays, corn cobs and ground wood to inhibit the growth of odor-causing bacteria. The suggested application rate of Bioban™ BP-Plus Pres in clay, corn cob, and ground wood applications, is 25-200 ppm impregnated on the materials generally in a prepared solution.
Adhesives
Bioban™ BP-Plus Pres is effective and compatible in most water-based adhesive formulations including dextrin, clay and polyvinyl acetate containing systems. A typical treatment level of 100-5000 ppm is recommended.

Starch and Pigment Slurries

Bioban™ BP-Plus Pres is useful for the control of bacterial growth in aqueous system such as starch suspensions and pigment slurries. Add Bioban™ BP-Plus Pres at, or close to, the end of the manufacturing process, either as a solid or pre-dispersed in a quantity of the process water. Bioban™ BP-Plus Pres should be dosed at 100-500 ppm.

Paints, Latex, and Antifoam Emulsion Systems

Bioban™ BP-Plus Pres provides in-can preservation and prevents bacterial spoilage during shelf-life storage of styrene- acrylic, polyvinyl acetate and other latex emulsion concentrates and latex emulsion based paints. It is also effective for the preservation of silicone and other antifoam emulsion systems. Bioban™ BP-Plus Pres can be added at any convenient point during the manufacturing process. Ideally, it should be added as a final step just prior to packing the product into bulk or sales packs. Bioban™ BP-Plus Pres should be dosed at 100-500 ppm.

Water-Based Printing Inks and Fountain Solutions

Bioban™ BP-Plus Pres can inhibit the growth of spoilage bacteria during the storage and use of water-based printing inks and fountain solutions. For in-can preservation of inks, Bioban™ BP-Plus Pres should be added as a final step and should be dosed at 100-500 ppm. To control bacterial spoilage during the use of fountain solutions, Bioban™ BP-Plus Pres should be shock dosed at a suitable point in the fountain reservoir where there is adequate flow or agitation to insure quick dissolution. Bioban™ BP-Plus Pres may be shock dosed once or twice weekly as a normal routine. Where conditions indicate, more frequent shock dosing may be required. In fountain solutions, Bioban™ BP-Plus Pres should be shock dosed at 25-100 ppm.

Oil Production

Bioban™ BP-Plus Pres may be used to control aerobic and anaerobic bacteria, especially sulfate-reducing bacteria, in oil and gas-related production. Bioban™ BP-PLUS Preservative may be dosed at any convenient point in the process. The dose rate for oil flooding/injection waters, enhanced oil recovery fluids, produced water, drilling fluids, fracturing fluids and workover and completion fluids is 50-100 ppm Bioban™ BP-Plus Pres. The dose rate of active ingredient for well squeeze fluids and fracturing fluids is 25-200 ppm.

Oil and Gas Transportation and Storage

Bioban™ BP-Plus Pres may be used to control aerobic and anaerobic bacteria that contribute to corrosion in pipeline maintenance and water bottoms in oil or transportation tanks. The dose range for water bottom in oil or transportation tanks is 50-100 ppm in the aqueous phase. For pipeline maintenance the dose range is 25-200 ppm.

The active ingredient in Bioban™ BP-Plus Pres, bronopol, is compatible with a range of materials used in water treatment, pulp and paper and other process applications. The materials include compounds such as scale inhibitors, pitch stabilizers, sizing agents, retention aids, flocculants and other biocides. However, strong reducing agents such as bisulfite (>50 ppm), oxidizing agents such as free residual chlorine (>5 ppm) and secondary amines should be avoided. It is also recommended that Bioban™ BP-Plus Pres not be subjected to temperatures greater than 40°C/104°F in order to avoid its decomposition. For formulations that will be repeatedly exposed to microbial challenges during storage and use (user opening and closing product container) the optimum pH range of use is below 8; however, products that are greater than pH 8 can still be preserved with Bioban™ BP-Plus Pres. Testing should be performed to confirm that Bioban™ BP-Plus Pres Preservative meets the preservation requirements outlined for the product. Bioban™ BP-Plus Pres can be used alone or in combin- ation with other biocides. The use of multiple preservatives provides additional protection against bacterial and fungal spoilage. In addition, combination systems are often more cost effective. Multiple biocide combinations help prevent the establishment of populations of organisms resistant to a single biocide. Bioban™ BP-Plus Pres can be used with a wide variety of biocides. The most popular combinations are those with 5 chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4- isothiazolin-3-one (CMIT/MIT) or 1,2-benzisothiazolin-3-one (BIT). The dosage levels of CMIT/MIT, typically 25-30 ppm active ingredient for preservation applications, can be reduced to 7.5 to 15 ppm active ingredient when combined with 100-200 ppm (active ingredient) Bioban™ BP-Plus Pres. The benefits of the combination of these two actives are as follows:

• Synergistic activity has been reported between bronopol and isothiazolinones in both the USA and Japan.
• Pseudomonas efficacy – BIOBANᵀᴹ BP-PLUS Preservative demonstrates excellent efficacy against Pseudomonas, a weakness of isothiazolinone chemistry.
• BIOBANᵀᴹ BP-PLUS Preservative is more effective in the presence of reducing agents as compared to isothiazolinones. In addition, BIOBANᵀᴹ BP-PLUS Preservative can improve the stability of CMIT/MIT in the presence of reducing agents.

At normal use rates Bioban™ BP-Plus Pres is compatible with a wide range of metals. However, the solid or its concentrated solutions can be corrosive to some metals if left in contact for prolonged periods. Care must be taken, therefore, to wipe up and/or wash down all spills where these may lead to prolonged contact with metals. Store the product in its original container, tightly closed in a safe place away from foodstuffs. Wash out the empty container thoroughly and dispose of safely. Minor spillages may be flushed away with plenty of water. Major spillages must be treated with a suitable absorbent carrier which may then be swept up and contained for disposal in accordance with local requirements.
