Linoleic acid (CAS 60-33-3) is a fundamental omega-6 polyunsaturated fatty acid that plays a critical role in human health and finds diverse applications across industries. As a colorless to straw-colored liquid, its physical characteristics and sensitivity to environmental factors like air and light dictate specific handling and storage protocols to ensure its potency and purity.

Understanding the specifications of linoleic acid is crucial for quality assurance. Typically, it is characterized by its high purity, with Linoleic acid content ranging from 55% to 95%. Key quality indicators include an acid value typically exceeding 190 mgKOH/g, signifying the presence of free fatty acids, and a very low water content, generally ≤0.1%. These parameters are vital for its use in sensitive applications such as pharmaceuticals and high-performance industrial products.

The sensitivity of linoleic acid to oxidation means that proper storage is paramount. To maintain its integrity and extend its shelf life, it should be stored in a cool, dry, and dark environment. Unopened containers generally have a storage life of 24 months, provided they are kept under these conditions. The product is commonly supplied in large-volume packaging such as 1000L Intermediate Bulk Containers (approximately 950KGS) or 180kg drums, ensuring availability for various industrial and commercial needs.

For both nutritional and industrial purposes, adhering to recommended handling and storage practices ensures that linoleic acid retains its beneficial properties. Whether used for its health benefits in pharmaceuticals or its functional properties in coatings and surfactants, maintaining the quality of this essential fatty acid is key to achieving desired outcomes. Manufacturers and end-users alike must pay close attention to these details to maximize the value derived from this versatile compound.
