TOXICITY AND SAFETY
For information on the toxicity and safe handling of this product, please read the Material Safety Data
Sheet prior to use of the product.

HANDLING AND STORAGE
SURFONIC LF-37 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.

SHIPPING DATA
Product is available in tank cars, tank trucks and drums of 450 pounds (204 kilograms) net weight. Small
samples are available upon request.

BIODEGRADABILITY AND ENVIRONMENTAL SAFETY
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 with SURFONIC LF-17.

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 (POLY-TERGENT?
SLF-18) shows it to be much less toxic to aquatic life than alcohol ethoxylates (water flea, LC50, 72 ppm;
fathead minnow, LC50, 13 ppm).
