Description

Acidulated Linseed Soapstock is a specialized derivative of linseed oil processing, primarily composed of free fatty acids and other lipid-soluble components. This product is valued for its role as a cost-effective, renewable feedstock and intermediate in various industrial synthesis processes. It serves as a critical raw material for manufacturers in the oleochemical, lubricant, and surfactant industries seeking sustainable alternatives to petroleum-based inputs.

Application

• Oleochemical Intermediate: Serves as a key starting material for the production of fatty acid esters, metallic soaps (e.g., calcium or zinc soaps), and other derivatives.
• Bio-lubricant & Grease Formulation: Used in the manufacturing of environmentally friendly lubricants, greases, and mold release agents.
• Surfactant & Emulsifier Production: Acts as a feedstock for synthesizing anionic surfactants and emulsifying agents for industrial and cleaning applications.
• Animal Feed Supplement: Utilized as an energy-dense fat source and fatty acid supplement in livestock and poultry feed formulations.
• Corrosion Inhibitor Precursor: Employed in the development of corrosion-inhibiting coatings and additives for metalworking fluids.
• Polymer & Resin Modifier: Functions as a plasticizer or modifying agent in certain polymer and resin systems to alter flexibility and processing characteristics.

Quality Control

Our Acidulated Linseed Soapstock is produced and controlled under a stringent quality management system to ensure batch-to-batch consistency and reliability. Key parameters such as acid value, saponification value, moisture content, and fatty acid profile are routinely monitored. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from strong acids, strong oxidizers, and heat sources. Recommended storage temperature is between 15°C and 25°C. As a natural product derivative, prolonged storage at elevated temperatures should be avoided to prevent degradation.
