Product Description
Tall Oil Fatty Acid (TOFA) CAS 61790-12-3 is a distilled tall-oil fatty-acid mixture; it is a UVCB material.
Synonyms: Tall oil fatty acid; TOFA; distilled tall oil fatty acid.
CAS: 61790-12-3.
Molecular formula: Not specified (mixed fatty-acid material).
It is supplied as a pale-yellow to amber or darker viscous liquid.
It is obtained by distilling crude tall oil from the Kraft wood-pulping process.
It consists mainly of oleic and linoleic acids, with smaller amounts of other fatty acids and low rosin-acid or unsaponifiable matter.
It is used in alkyd resins, dimer acids, metalworking fluids, lubricant esters and corrosion inhibitors.
It is also used in soaps, detergents, surfactants, ore flotation, oilfield chemicals, rubber processing aids, inks and adhesives.
It is not a single pure fatty acid; its composition can vary with the distillation cut.
Grades are selected by acid value, rosin-acid content and iodine value.
The rosin-acid level and iodine value affect reactivity, colour stability and suitability for downstream processes.
For purchasing, specify the target resin or process route and the agreed analytical controls.
Keep containers closed and follow the current SDS for storage, temperature and handling.
Use suitable PPE and exposure controls when handling the material.
Confirm acid value, rosin-acid content, iodine value, colour, moisture and physical consistency on the COA.
Confirm grade, packaging, and specification as required.

FAQ - Technical & Supply Chain
-
Q:
What is Tall Oil Fatty Acid (TOFA) CAS 61790-12-3?
A: Tall Oil Fatty Acid, abbreviated TOFA, is a natural fatty-acid mixture obtained by distilling crude tall oil from the Kraft wood-pulping process. It carries CAS 61790-12-3 and is supplied as a pale-yellow to amber or darker viscous liquid whose exact colour and composition depend on the distillation cut. -
Q:
How is TOFA obtained and what is its typical fatty-acid composition?
A: TOFA is recovered as a co-product when crude tall oil from conifer pulping is fractionally distilled under vacuum. It consists mainly of oleic and linoleic acids, with smaller amounts of palmitic, stearic, conjugated linoleic and other fatty acids, plus low levels of rosin acids and unsaponifiable matter in refined grades. -
Q:
What are the main applications of TOFA?
A: TOFA is used in alkyd resins for paints and varnishes, dimer acids and other chemical intermediates, metalworking fluids, lubricant esters and corrosion inhibitors. It is also used in soaps, detergents, surfactants, ore flotation, oilfield chemicals, rubber processing aids, inks and adhesives. -
Q:
Why is TOFA used in alkyd resin production?
A: The C18 fatty-acid chain and unsaturated double bonds in TOFA react with polyols and polyacids to form the fatty-acid backbone of an alkyd resin. This helps control film flexibility, drying performance and final coating properties while offering a renewable, cost-effective feedstock. -
Q:
Which specification parameters should be compared between TOFA grades?
A: Compare acid value, iodine value, rosin acid content, unsaponifiable matter, colour, moisture and viscosity or density. The rosin acid level and iodine value are especially important because they affect reactivity, colour stability and suitability for alkyd, dimer-acid or surfactant applications. -
Q:
Is TOFA the same as oleic acid?
A: No. Oleic acid is one defined fatty acid, while TOFA is a variable mixture of fatty acids whose principal components are oleic and linoleic acids. Because TOFA is a UVCB material, its rosin acid, colour and unsaturation profile can change with the source and distillation grade.
