Carbohydrate Polymers, 2006 The antibacterial efficiency of poly(hexamethylene biguanide), PHMB, on un-dyed cotton has been compared with that of PHMB on cotton coloured with a range of reactive dyes. In each case, the presence of covalently bound dye resulted in a reduction in antibacterial efficiency. In the absence of dye, the cationic PHMB binds to the cotton via weak ion-ion

Biomaterials, 2014 An effective amount of the antiseptic agent PHMB cannot simply be placed on the surface of titanium alloys where hydrocarbons were removed by different purification procedures. Pre-treatment of Ti6Al4V specimen with 5% H2O2 in 24 h results in extra introduced -OH and -COOH groups as well as an adsorbed water film on the surface, which provide the base ...

Polyhexamethylene biguanide (PHMB) is a widely used bacteriocide. It is marketed as an aqueous solution of its hydrochloride from which it is readily adsorbed onto cotton, this process depending upon the ability of the cationic PHMB to form electrostatic links with the anionic carboxylate groups present on cotton.

Coloration Technology, 2004 Poly(hexamethylene biguanide) (PHMB) is of interest as a bactericide for fabrics. It has affinity for cotton by reaction with the cellulosic carboxylate groups. In this study, the capacity of undyed cotton to absorb PHMB has been determined and compared with cotton dyed with anionic bis(monochlorotriazinyl) reactive dyes. When cotton is dyed with these

International endodontic journal, 2011 Aim was tTo test the efficacy of poly(hexamethylene biguanide) hydrochloride (PHMD) as a root canal irrigant against E.faecalis and P.aeruginosa in an experimental model ex vivo. Crowns and apical parts of twenty-two extracted single rooted human teeth were removed with diamond burs and root canals were instrumented with Hedström files to size #40 ...

Frequently used biocidal disinfectants, including quaternary ammonium compounds (QAC), glutaraldehyde and poly(hexamethylene biguanide) hydrochloride (PHMB), occur in the aquatic environment but their potential effects in fish are poorly known, in particular when occurring as mixtures.
