Used as a heat stabilizer in polyvinyl chloride (PVC) and other polymers to prevent degradation during processing. Acts as a lubricant in plastic and rubber manufacturing, improving flow and mold release. Employed in the production of coatings, inks, and adhesives for its water-repellent and film-forming properties. Also serves as a drier in paints and varnishes, accelerating the curing process by promoting oxidation of drying oils. Historically used in cosmetics and skincare products, though such uses have declined due to toxicity concerns.
