What is Dalbac BG (PHMB)?

Polyhexamethylene Biguanide (PHMB) is a polymeric biguanide compound known for its antimicrobial properties. It is used in a variety of applications due to its effectiveness against a wide range of microorganisms, including bacteria, viruses, and fungi.

Where and When was PHMB Discovered?

Polyhexamethylene Biguanide (PHMB) was developed in the mid-to-late 20th century by Imperial Chemical Industries (ICI) as an effective antimicrobial agent. Initially used in industrial water treatment to control microbial growth, PHMB’s broad-spectrum antimicrobial properties led to its adoption in medical and healthcare settings, including wound care, contact lens solutions, and skin antiseptics. It was later incorporated into personal care products like cosmetics and shampoos as a preservative. Regulatory approvals from bodies like the EPA and ECHA facilitated its widespread use. Research and innovations continue to enhance its applications and efficacy.
