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

Preservation and Antibacterial: Its antibacterial properties allow it to replace traditional preservatives in rinse-off 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:

Flavor and 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 used as emulsifiers in detergent formulations.
