Stearic-Arachidic Acid is a mixture of stearic acid and arachidic acid, which are long-chain saturated fatty acids. This product is known for its versatile applications across various industries due to its unique properties. It appears as a white or off-white wax-like solid with a melting point typically within the range of 60-70°C. The mixture is insoluble in water but is soluble in organic solvents such as ethanol, ether, and chloroform.

This fatty acid mixture is used in the production of fatty alcohols and their derivatives, esters, amides, surfactants, and pharmaceutical intermediates。 It finds applications in coatings, personal care products, and industrial cleaning products, where it serves as a lubricant, emollient, or consistency agent。 Additionally, Stearic-Arachidic Acid is utilized in paper chemicals, engineering plastics, and as a defoamer.

The mixture's high melting point and waxy texture make it suitable for applications requiring a solid, stable product at room temperature. Its compatibility with various materials and its ability to modify surfaces and improve flow properties in composite systems contribute to its wide industrial use. Stearic-Arachidic Acid is also valued for its lubricating properties, which can enhance the workability of materials and promote a reduction in surface energy, increasing the hydrophobic character of treated surfaces.
