Polihexanide, also known by the brand name PHMB, is a broad-spectrum antimicrobial agent used primarily as a topical antiseptic. It is effective against a wide range of Gram-positive and Gram-negative bacteria, fungi, and viruses. It is commonly used in wound care products, sterile dressings, and other medical devices. It is also used in oral hygiene products, such as mouthwashes, and as a preservative in cosmetics and other personal care products. Polihexanide is generally considered to be safe and non-irritating when used as directed.
Polihexanide, also known as polyhexamethylene biguanide (PHMB), is a broad-spectrum antiseptic and disinfectant solution [1, 2]. Here's a closer look at its properties and uses:
Function: Polihexanide works by disrupting the cell membranes of bacteria, fungi, and some viruses [1]. This disrupts their growth and function, ultimately killing them.
Applications: Polihexanide has various applications in both healthcare settings and consumer products due to its broad-spectrum antimicrobial activity:
- Skin and wound antisepsis: It's used to clean and disinfect the skin before injections, surgery, or wound care to reduce the risk of infection [1, 2].
- Wound irrigation: In some cases, diluted solutions might be used to irrigate wounds to help prevent infections [3].
- Catheter care: Polihexanide solutions can be used for cleaning and disinfecting catheters to help prevent catheter-associated infections [4].
- Consumer products: It can be found in some hand sanitizers, antiseptic wipes, and household disinfectants [2].
Important Considerations:
- Effectiveness: Polihexanide is generally considered effective against a broad range of germs, but it may not be as potent as some other antiseptics against certain pathogens [2].
- Potential for Skin Irritation: While generally well-tolerated, some people may experience skin irritation, especially with prolonged use [2].
- Not a Substitute for Good Hygiene: Polihexanide should not be used as a replacement for proper handwashing practices or other infection control measures [5].
