Description

Tall Oil Fatty Acid is a versatile, naturally-derived mixture of unsaturated fatty acids, primarily oleic and linoleic acids, obtained from the distillation of crude tall oil. This renewable resource is valued for its excellent reactivity and cost-effectiveness as a bio-based alternative to petrochemical-derived fatty acids. It serves as a critical raw material for manufacturers in the chemical synthesis, polymer, and surface treatment industries seeking sustainable and high-performance intermediates.

Application

• Soaps & Detergents: Used as a primary feedstock in the saponification process for producing metallic soaps (e.g., calcium, zinc soaps) which act as driers, stabilizers, and thickeners.
• Alkyd Resins & Coatings: A key component in the formulation of alkyd resins, contributing to flexibility, drying properties, and durability in paints, varnishes, and protective coatings.
• Intermediate for Chemical Synthesis: Serves as a starting material for producing dimer acids, polyamide resins, lubricant additives, and other specialty chemicals.
• Flotation Agents: Employed in the mining industry as collectors in the froth flotation process for separating minerals from ores.
• Fuel Additives: Utilized in the production of biodiesel and as components in fuel oil additives to improve combustion and stability.
• Rubber & Plastic Additives: Acts as a processing aid, internal lubricant, and release agent in the compounding of rubber and plastic materials.

Quality Control

Our Tall Oil Fatty Acid is produced under stringent quality management systems to ensure batch-to-batch consistency and performance. Each lot is analyzed against key parameters including acid value, rosin acid content, and fatty acid composition. Certificates of Analysis (COA) documenting purity, color, and other critical specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. As this product is easily oxidized, storage under an inert atmosphere (e.g., nitrogen) is recommended for long-term preservation of quality. Recommended storage temperature: 15-25°C.
