Poly (hexamethylenebiguanide) hydrochloride CAS No:32289-58-0 (C8H17N5)n.xClH

Core Applications

‌1. Broad-Spectrum Antibacterial and Disinfectant: As a highly effective and environmentally friendly polymer-based antibacterial agent, it exhibits strong bactericidal activity against Gram-positive bacteria, Gram-negative bacteria, fungi, and yeasts. It is widely used in water treatment, swimming pool disinfection, and sterilization of public spaces, and does not cause microorganisms to develop resistance.

‌2. Industrial Applications: Used in the textile industry for the antimicrobial treatment of fibers and fabrics; in the paper industry for mold prevention in paper; and in oil extraction, agriculture, and aquaculture to inhibit microbial growth and prevent equipment corrosion and water quality deterioration.

‌3. Personal Care and Hygiene Products‌: Added to laundry detergents, sanitary napkins, wet wipes, and household disinfectants; it can also serve as a mild preservative in cosmetic formulations. It is non-irritating to the skin and mucous membranes and is highly safe.

4. Pharmaceuticals and Research: Used as a medical disinfectant in contact lens solutions, eye drops, and for sterilizing surgical instruments; also used as an adjunct treatment for Acanthamoeba keratitis; and serves as a pharmaceutical intermediate and biochemical reagent in research on antimicrobial activity.

‌5. Preservative Additive for Materials‌: Used as a preservative in coatings, latex paints, adhesives, and water-based polymer systems to prevent mold growth and deterioration during storage, thereby extending the service life of the products.
