SURFONIC® LF-17

• Mechanical dishwashing
• Laundry detergents
• Pulp and paper processing
• Metal cleaning

• The SURFONIC® LF-series products are considered to be biodegradable; however, the rate of biodegradation is retarded because of the polyoxypropylene chain in the products.
• Removal of organic carbon reached 40% after 71-85 days in a laboratory activated sludge study.
• The SURFONIC® LF surfactants are expected to exhibit aquatic toxicity similar to or less than that of alcohol ethoxylates.
• Study of a low foam surfactant similar to SURFONIC® LF-17 surfactant shows it to be much less toxic to aquatic life than alcohol ethoxylates (water flea, LC50, 72 ppm; fathead minnow, LC50, 13 ppm).

Product is available in tank cars, tank trucks and drums of 440 pounds (199 kilograms) net weight.

• SURFONIC® LF-17 surfactant may be satisfactorily stored in carbon steel tanks using steel pipes and pumps.
• Caution must be exercised, however, to keep the material in the anhydrous state to prevent severe corrosion to the carbon steel tank and related equipment.
• A drier on the breathing nozzle is recommended to help maintain anhydrous conditions in the storage tank.
• For longer term color stability, it is recommended that the product be stored under an inert atmosphere.
• Solid sediment may form upon standing.
• There should be circulation in the storage vessel to keep solids suspended.
• Low pressure steam coils in storage tanks and steam tracing of transfer lines should be provided in cases where low environmental temperatures may make pumping of the product difficult.
