Tall Oil Fatty Acid, TOFA | CAS 61790-12-3

Description

Tall Oil Fatty Acid (TOFA) is a natural, renewable fatty acid derived from the distillation of crude tall oil, a byproduct of the Kraft pulping process. It consists primarily of oleic acid, linoleic acid, and conjugated linoleic acids, making it a versatile raw material for industrial applications. TOFA is valued for its high reactivity, biodegradability, and cost-effectiveness in coatings, lubricants, and biofuels.
