Tallow acid

Tallow acid (CAS 61790-37-2), also sold as fatty acids tallow, is a mixed long-chain fatty acid blend derived from animal tallow; predominantly composed of oleic, stearic, and palmitic acid fractions.

Where is Tallow acid used?

• Rubber and tire compounding: internal lubricant and processing aid that improves filler dispersion and reduces mill sticking
• Coatings and alkyd resins: reactive fatty acid component controlling drying characteristics and film flexibility
• Textile and leather finishing: modifies surface friction and improves fiber or hide lubricity
• Metalworking fluids: base component in soaps and emulsifiable oils, where consistent fatty acid chain distribution supports stable emulsification

Good to know: Standard commercial grades include technical grade, with specifications typically defined by acid value and iodine value; the titer point indicates the specific saturation level of the batch. Distilled grades are available where tighter fatty acid profile control is required.
