1,8-Octanediol

　　Application Fields

　　Polymer Materials:

　　Polyesters and Polyurethanes: Copolymerized with diacids (such as adipic acid) as a diol monomer to prepare high-strength fibers, thermoplastic elastomers, and coatings.

　　Functional Modification: After copolymerization with methyl methacrylate (MMA), modification via bromination or hydroxylation can regulate the hydrophilicity and flame retardancy of the polymer.

　　Cosmetics and Personal Care:

　　Moisturizing and Emolliency: Used as a gentle moisturizer in creams and lotions to enhance skin barrier function; representative brands include Lancôme and Estée Lauder.

　　Preservation and Antibacterial Properties: Its antibacterial characteristics allow it to replace traditional preservatives in rinse-free skincare products.

　　Pharmaceuticals and Biomaterials:

　　Pharmaceutical Intermediates: Used in the synthesis of anticoagulants, antibiotics, and steroid drugs.

　　Biodegradable Materials: When compounded with chitosan, it can be used to prepare absorbable sutures and tissue engineering scaffolds.

　　Fine Chemicals:

　　Fragrance Synthesis: Used as a precursor for musk fragrances to impart long-lasting scents to products.

　　Plasticizers and Surfactants: Improve the flexibility of plastics or act as emulsifiers in detergent formulations.
