Description

Fatty Acids, Tall-Oil, Monoesters With Sorbitan is a non-ionic surfactant derived from the esterification of tall oil fatty acids with sorbitan. This compound matters for its excellent emulsifying, dispersing, and lubricating properties, making it a versatile intermediate and functional additive. It is needed by manufacturers in the chemical, coatings, textile, and personal care industries seeking effective, bio-based surface-active agents.

Application

• Primary emulsifier and co-emulsifier in agricultural formulations, pesticide emulsions, and herbicide concentrates.
• Key component in industrial lubricants and metalworking fluids for its lubricity and corrosion inhibition.
• Used as a dispersing agent and grinding aid in pigment preparations, coatings, and ink systems.
• Intermediate in the synthesis of more complex surfactants, such as polysorbates (e.g., Tween series).
• Functional additive in textile processing for fiber lubrication and softening.
• Emulsifier and stabilizer in select personal care and cosmetic formulations.
• Processing aid and internal lubricant in polymer and plastic production.

Quality Control

Our Fatty Acids, Tall-Oil, Monoesters With Sorbitan is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance and meets agreed-upon specifications. A Certificate of Analysis (COA) detailing key parameters such as acid value, saponification value, hydroxyl value, and moisture content is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent oxidation and moisture absorption. Keep away from strong oxidizing agents.
