PHMB application:

• PHMB is used as a preservative and as an antimicrobial agent.

• PHMB is used in cosmetics

• PHMB is used in personal care products

• PHMB is used in fabric softeners

• PHMB is used in contact lens solutions

• PHMB is used in hand washes

• In cosmetics, PHMB is used as a broad spectrum preservative. It is freely water soluble and therefore widely used in water-based products which are most susceptible to microorganism growth. It has an excellent activity against a wide range of Gram positive and Gram negative bacteria, fungi and yeasts and is particularly effective against microorganisms such as Pseudomanas species, which are difficult to control.

• PHMB is also used to preserve wet wipes; to control odour in textiles; to prevent microbial contamination in wound irrigation and sterile dressings; to disinfect medical/dental utensil and trays, farm equipment, animal drinking water, and hard surfaces for food handling institutions and hospitals; and to deodorize vacuums and toilets.

• PHMB is used in antimicrobial hand washes and rubs and air filter treatments as an alternative to ozone. PHMB is also used as an active ingredient for recreational water treatment, as a chlorinefree polymeric sanitizer, which is effective against a wide variety of microorganisms.

• Further reported uses of PHMB are purification of swimming pool water, beer glass sanitisation, solid surface disinfection in breweries and short-term preservation of hides and skins.
