In the food industry, it serves as a stabilizer and thickener in various products, enhancing texture and shelf life. In cosmetics, it is incorporated into creams and lotions to improve product stability and smoothness. Additionally, it is employed in the production of inks, adhesives, and coatings, where it improves durability and flexibility. Its water-insoluble yet organic solvent-soluble properties make it a versatile component in industrial applications.
