Used as a plasticizer in plastics to increase flexibility and durability, especially in cellulose-based plastics like cellulose acetate and cellulose nitrate. Commonly found in adhesives, printing inks, and coatings due to its good solubility and compatibility with various resins. Also used in cosmetics and personal care products as a solvent and fragrance carrier, though its use is declining due to regulatory and health concerns. Provides improved workability and stability in formulations requiring low volatility and moderate flexibility.
