Polyhexamethylene Biguanide (PHMB) CAS 32289-58-0

Polyhexamethylene Biguanide (PHMB) is supplied as a polymeric antimicrobial active ingredient designed for use in industrial and formulation-based systems requiring microbial control. It is commonly applied in water treatment programs, hygiene-related formulations, and material preservation systems where control of bacteria and algae is required.

In commercial supply, PHMB is typically provided as an aqueous solution with defined active content suitable for direct formulation use. It is delivered in standard industrial packaging for liquid handling, with supporting documentation such as COA, TDS, and SDS available to support procurement and regulatory evaluation.

Packaging

PHMB is supplied as a liquid product in sealed drums, IBC containers, or bulk delivery systems suitable for industrial use. Packaging materials are selected for compatibility with aqueous biocidal formulations and designed to maintain product stability during storage and transport.

Container formats can be aligned with order volume and handling requirements, with attention to clean filling, secure sealing, and export-ready preparation.

Storage

Store in a cool, dry, and well-ventilated environment, away from direct sunlight and sources of heat. Containers should be kept tightly closed to prevent contamination and maintain product stability.

Avoid contact with strong oxidizing agents. Maintain original packaging integrity during storage and transport.

FAQ

Are there regulatory considerations for use?
Yes, application and allowable use levels should be evaluated according to local regulatory requirements.

Is PHMB a single chemical compound?
No, it is a polymeric substance consisting of repeating biguanide units, typically supplied as a formulated aqueous solution.

What is the main function of PHMB in industrial use?
It acts as an antimicrobial agent for controlling bacteria and algae in various systems.

What supply form is most common?
It is commonly supplied as an aqueous solution with defined active content for direct use in formulations.
