SYLFAT™ 2, Tall Oil Fatty Acid (TOFA) has a high fatty acid content and a low content of rosin acids and unsaponifiables. It provides a combination of light color, good color stability and air-drying properties. The utility of SYLFAT™ 2, Tall Oil Fatty Acid can be found in the long carbon chain (C18), acid function of the carboxyl group (COOH) and unsaturation of the double bonds.

Packaging & Availability

Packaging
  • SYLFAT 2 Tall Oil Fatty Acid is delivered as a liquid in tank trucks, ISO containers, rail cars, flexi tanks, IBC’s or steel drums (as available).
  • Typical delivery temperature is 10 – 30 °C (50 – 86 °F)

Storage & Handling

Storage

SYLFAT 2 Tall Oil Fatty Acid should be stored dry and below 25 °C (77 °F), and away from direct sunlight. The product must be retested after longer storage to ensure the properties are within specification limits. Since color changes of >1 Gardner unit can be seen over time due to oxygen or heat exposure, testing of product in applications sensitive to color is recommended prior to use. If precipitation occurs, it does not affect the use of the product as a chemical raw material. Slight heating to about 40 °C (104 °F) dissolves the precipitated material.
