Bioban™ DXN Antimicrobial

• Broad spectrum efficacy
• Non-formaldehyde release and non-formaldehyde containing
• Soluble in water and in oil (hydrocarbons)
• Effective over a wide pH range (3-8)
• Non-halogenated, non-phenolic and non-metallic
• Compatible with anionic, cationic and non-ionic compounds

Bioban™ DXN Antimicrobial is a microbial growth inhibitor for use only in industrial water-based products. The dosage rate for all label applications is 0.1%-0.2% by weight (1000-2000 ppm).

Adhesives

Bioban™DXN Antimicrobial is an effective preservative for industrial adhesive formulations. BIOBAN™ DXN Antimicrobial is compatible with most adhesive formulations, including starch and polyvinyl acetate.

Textile Chemicals and Finishes

Microbial contamination of textile chemical specialties causes breakdown of the working properties of these chemicals as well as foul odors, rancidity, acidity, discoloration, and deterioration of the fibers and fabric. Bioban™ DXN Antimicrobial is an especially effective preservative or controlling microbial contamination in various textile chemical specialties. Bioban™ DXN Antimicrobial as been used effectively in dye levelers, fiber lubricants, spinning emulsions, softeners, antistats, sizings, dyes, dye dispersions, dye pastes and textile adhesives.

Specialty Industrial Products

Bioban™ DXN Antimicrobial is an effective antimicrobial for use in specialty industrial products such as pigment slurries, thickeners and gums, dyestuffs, inks and lignosulfonates. These products often contain raw materials that are heavily contaminated with various microorganisms or contain ingredients that are excellent nutrients for microbial growth.

Silicone Emulsions

Bioban™ DXN Antimicrobial is particularly effective for the preservation of bulk silicone emulsions. It is also effective for the preservation of silicone and oil-based emulsions that are used in antifoam emulsion systems.

Paints, Coatings and Polymer Emulsions

Bioban™ DXN Antimicrobial inhibits microbiological growth during shelf-life storage of PVC, PVA, acrylic, polyethylene and other latex emulsion concentrates and latex emulsion- based paints.

Bioban™ DXN Antimicrobial functions over a wide pH range of 3-8. The product is not effective in systems with a pH over 9. Limited efficacy is seen between pH 8 and 9. BBioban™ DXN Antimicrobial should not be used in systems containing high levels of ammonia and/or amines. Yellowing and inactivation of Bioban™ DXN Antimicrobial occurs under these conditions. Due to the hydrolysis of Bioban™ DXN Antimicrobial to acetic acid, acetaldehyde and aldol, the released acetic acid may cause the pH of the system to drop slightly. If pH drift is of concern, the pH can be adjusted by adding 30g of sodium carbonate for every 100g of Bioban™ DXN Antimicrobial. Avoid the use of sodium or potassium hydroxide to adjust the pH as these compounds may result in color formation. Ammonium hydroxide should not be used because it will inactive the biocide. A neutralized solution of 10% Bioban™ DXN Antimicrobial in water resulting in a pH of 7.0- 7.1 can also be prepared.

Upon addition to aqueous systems, Bioban™ DXN Antimicrobial undergoes hydrolysis to its microbiologically active components acetaldehyde, aldol, and acetic acid. The ability of Bioban™ DXN Antimicrobial to inhibit growth of microorganisms is shown in the table of minimum inhibitory concentrations (MIC) for representative spoilage bacteria and fungi. The MIC values indicate the concentration of preservative needed (in ppm) to control a particular organism. The lower the number, the greater the effectiveness of the biocide. Although values shown do not necessarily indicate dosage levels required in the formulated product, they are indicative of the spectrum of antibacterial activity of the preservative.

First aid

• If swallowed, drink a large quantity of water. Do not induce vomiting. Immediately contact a physician or Poison Control Center.
• If inhaled, remove to fresh air and call physician immediately.
• If on skin, wash thoroughly with soap and water. Flush with large quantities of water.
• If in eyes, flush eyes immediately with plenty of clear water for at least 15 minutes. Immediately contact physician.
• If on clothing, remove contaminated clothing and wash before reuse.

Precautionary labeling

Labels for Bioban™ DXN Antimicrobial bear these caution statements: Caution! Harmful if swallowed or absorbed through the skin. Causes moderate eye irritation. Avoid contact with eyes, skin or clothing. Prolonged or frequently repeated skin contact may cause allergic reaction in some individuals. Wash thoroughly with soap and water after handling.

Workers handling Bioban™ DXN Antimicrobial should wear impervious gloves, chemical goggles, and an impervious apron. In case of contact, wash exposed skin with plenty of water. If in the eyes, flush the eyes with plenty of water for at least 15 minutes. Hold eyelid open and move eye from side to side to assure complete rinsing. See a physician. Product should be stored in its original container under normal ambient conditions. Do not store in locations near sources of heat. If spilled, use dikes to prevent the spill from entering bodies of water or sewers. Absorb with appropriate material and send to an approved incinerator.
