Preservation of Fresh Animal Hides and Skins
For the preservation of fresh animal hides and skins prior to use. During processing, use 15fl.oz. to 3Gal. Add the appropriate quantity of PHMB to the brine solution during the curing operation or treat hides or skins with an appropriately diluted aqueous solution during other portions of the processing operations. The specific use rate and contact time needed to control microbial attack will depend upon the degree of decomposition of the hides or skins prior to treatment.
Dosage: 1.0 to 2.6 lbs. of PHMB per 1,000 lb. of hides or skins.
Cellulosic Materials and Textiles
PHMB can be used as an agent to control the growth and action of microorganisms, and control generation of odors, on textiles such as cotton, cotton blends, cellulosic materials, and synthetic fibers such as non-wovens, tissues, paper and pulps.
Dosage: PHMB is diluted and applied to give 0.025 to 2% on the dry weight of the substrate. Application is by conventional means such as padding, spraying, soaking or exhaustion. The optimum conditions for application of the dilute solution are pH 6.5 to 8 and temperature of 20 to 30°C.
The following are examples of products (substrates) suitable for antimicrobial finishing with PHMB:
- Textiles such as: Household products, for example, upholstery, carpet, curtains, wall covering, mops, dishcloths, yarns, cords, toweling and blankets.
- Cellulosics such as wipes, tissues, sponges, paper products (non-food contact) such as filters and cellulose pulp.
- Apparel items includes: slacks, shirts, underwear, sweatshirts, sweatpants, socks, oven mitts, slippers, bathrobes, gloves, hats, scarves, jackets, sheets, pillowcases, incontinence pads cover stock, washable incontinence briefs and panties.
Not for use in oil recovery systems that employ holding ponds for spent liquids.
Do not apply in, over or near marine and/or estuarine oil fields.
Dosage: Specific rates for use of PHMB should be determined by bacteriological tests made prior to treatment. These tests should establish (a) the presence of microorganisms, (b) the severity of the problem, and (c) required treating ratio. The effectiveness of a treatment can be evaluated by similar bacteriological tests. The compatibility of PHMB with the water should be determined prior to treatment. Some suggested treatment methods and treating rates for water systems include:
Oil Field Injection Water
- SLUG METHOD – When the system is noticeably fouled, apply 4 gallons of PHMB per 1,000 barrels (42,000Gal) of water (95.2ppm of product). PHMB should be added to the system at a point where it will be uniformly mixed. Repeat on a weekly basis, or as needed to establish control. When microbial control is evident, the treating rate may be lowered to 2 gallons of PHMB per 1,000 barrels of water (47.6ppm of product) weekly, or as needed to maintain control. Badly fouled systems should be cleaned before treatment is begun.
- CONTINUOUS METHOD – Before beginning a continuous treatment, apply a slug treatment of 4 gallons of PHMB per 1,000 barrels of water (95.2 ppm of product). Continue treatment by applying 0.15 to 0.8 gallons (19 to 102 ounces) of PHMB per 1,000 barrels of water (4 to 20 ppm of product).
- Calculate the total volume of drilling mud system, and using this volume calculate the number of gallons of PHMB needed to produce a concentration of approximately 3,000 ppm. For example, 126 gallons of PHMB per each 1,000 barrels of total volume will produce this concentration.
- While the system is circulating, add the amount of PHMB calculated above in a thin stream.
- As the well depth increases, increasing the total volume of the system, add additional PHMB as required to maintain the proper concentration.
- Calculate the total volume of the workover fluid system and, using this volume, calculate the number of gallons of PHMB needed to produce a concentration of approximately 3,000 ppm. For example, 60 gallons of PHMB per each 20,000 Gal (476 barrels) of total volume will produce this concentration.
- Add PHMB into the system
- Circulate the workover fluid system until the fluid returns clear.
- Shut the system down and idle for several hours. Remove the workover fluid. The well should be ready for productive use.
Aqueous Paints and Coatings
For the preservation of aqueous based Paints and Coatings such as paper and wood coatings, paints and coatings used for architectural product finishes, industrial finishes and special purpose coatings. Special purpose coatings include uses as a:
- Preservative for electrodeposition paints or solutions,
- Preservative for photo-plating solutions or coatings,
- Preservative in fount (or fountain) solutions used in the printing process as a maintenance fluid/coating and as a special coating for printing plates, and
- Preservative in spin finish coatings for fibers.
Dosage: 5 lb. to 50 lb. PHMB per 10,000 of product (500 to 5000ppm).
