Description

Poly(Hexamethylenebiguanide) Hydrochloride is a polymeric biguanide compound widely recognized for its potent and broad-spectrum antimicrobial activity. This versatile biocide is valued for its effectiveness at low concentrations and its relative stability across various formulations. It serves as a critical active ingredient for manufacturers in the personal care, pharmaceutical, water treatment, and industrial preservation sectors, where reliable microbial control is paramount for product safety and shelf life.

Application

• Disinfectant & Sanitizer Formulations: Used in surface disinfectants, hand sanitizers, and instrument sterilants for healthcare and food processing facilities.
• Personal Care & Cosmetic Preservation: Acts as a highly effective preservative in products like shampoos, conditioners, contact lens solutions, and wet wipes.
• Water Treatment: Employed as a biocide in industrial cooling water systems, swimming pools, and recreational water to control algae and bacteria.
• Pharmaceutical Applications: Used as an antimicrobial agent in topical antiseptics, wound care products, and as a preservative in certain sterile solutions.
• Industrial Process Preservation: Protects aqueous systems, metalworking fluids, adhesives, and paints from microbial spoilage.
• Textile & Material Treatment: Imparts antimicrobial properties to fabrics, polymers, and coatings.
