POLY QUAT
WATER TREATMENT
QUATERNARY BIOCIDES
CAS Number- 68424-95-3 and 68424-85-1
POLY QUAT is a radically new development based upon “Twin
Chain” quaternary ammonium compound technology. POLY QUAT , when
evaluated by accepted laboratory procedures, provides superior
bactericidal, algaecides and fungicidal activity far beyond that
achieved with other available quaternary ammonium compounds. This
provides the formulator with unequaled latitude in the design of
biocidal products.
Chemical Composition – Typical
Active Ingredients POLY QUAT
Alkyl (C14 50%, C12 40%, C16 10%) Dimethyl Benzyl Ammonium
Chloride 2.0%
Octyl decyl dimethyl ammonium chloride 1.5%
Dioctyl dimethyl ammonium chloride 0.6%
Didecyl dimethyl ammonium chloride 0.9%
Specifications
pH (1% Active Solution): 7.00
POLY QUAT contains 5% active polyquats. When used at:
-0.2% (2 mL/L), it generates 100 active ppm
-0.4% (4 mL/L), it generates 200 active ppm
-0.8% (8 mL/L), it generates 400 active ppm
-1.0% (10 mL/L), it generates 500 active ppm
Summary of the superior performance characteristics of POLY QUAT :
• Broad spectrum biocidal activity against both gram-positive and
gram-negative organisms.
• Increased hard water tolerance.
• Superior fungicidal performance.
POLY QUAT has been cleared by the FDA as an “Indirect Food Additive’’, under 21 CFR part 178.1010 at a concentration of 150-400 ppm active, and requires no water rinse. This clearance covers the usage of POLY QUAT on food processing equipment and utensils and food contact surfaces in public eating places. In addition, the use of sanitizing solutions based on POLY QUAT fulfills the criteria of the Grade “A” Pasteurized Milk Ordinance 1978 Recommendations of the United States Public Health Service.
Fungicidal Activity
Test Organism Ten Minute Killing Dilution (100% Active)
Trichophyton mentagrophytes 1:8000 (125 ppm)
APPLICATIONS
POLY QUAT will control algae and bacterial slimes found in recirculating cooling tower water and oil field water floods. They help clean and loosen slime deposits from cooling and flooding system surfaces. When used in slug doses, no other biocide is often required.
Application Recommended Use-levels on a 100% Active Basis
Recirculating Cooling Tower
- Initial Dosage 20-30 ppm
- Subsequent Dosages 7-10 ppm
Oil FieldWater Flood
- Continuous Addition 5-10 ppm
- Intermittent Addition 5-20 ppm
Recirculating Cooling Towers
Initially use 20 ppm active quaternary. Increase to 30 ppm if satisfactory results are not obtained. Repeat the initial dose every 7 days or more frequently if needed. Once control is achieved, lower dosage to 7-10 ppm to maximize cost performance. Repeat weekly as needed. Should slime develop again, go back to initial dosage. Cooling tower waters which are inherently low in algae growth and bacteria count may be adequately controlled by the lower range of these dosages, and slug fed every 7 days.
Oil Field Water Flood/Salt Water Disposal System
DO NOT APPLY IN MARINE AND ESTUARINE OIL FIELDS.
For control of slime-forming and sulfate-reducing bacteria in oil
field water flood or salt water disposal systems, add 5-10 ppm
active quaternary continuously. Levels for effective control will
vary depending on conditions at the site. For intermittent use, dose
at a rate of 5-20 ppm active
for 4-8 hours per day, one to four times a week as needed to
maintain control.
