Our Tall Oil Fatty Acid is refined through advanced distillation and purification processes, ensuring strict control over key indicators and consistent batch-to-batch quality. At 25°C, it presents as a clear liquid with a Fe-Co color value of 4 at maximum, and its rosin acid content is kept below 1% to minimize yellowing risk in end products. With an acid value of 195–207 mgKOH/g, iodine value of 110 gI₂/100g minimum, and saponification value of 196–208 mgKOH/g, it delivers balanced reactivity for resin synthesis and coating formulation. The product also features a low solidifying point of 8°C maximum and moisture content of 0.3% maximum, ensuring stable handling and storage even in cooler environments. Its fatty acid profile is precisely calibrated: C18:0 content is limited to 2.2% maximum, while C18:1 and C18:2 contents reach 50% and 32% minimum respectively, with other fatty acids accounting for no more than 15%. This optimized composition enhances emulsifiability, lubricity, and water resistance, while its compliance with GB/T industry standards guarantees reliability for alkyd resin manufacturing, dimer acid production, and metalworking fluid emulsification. As a renewable by-product of the papermaking industry, our TOFA aligns with global eco-friendly manufacturing trends, offering a sustainable, high-performance alternative to petroleum-based raw materials without compromising on quality or consistency.a
