Determination of biguanide groups in polyhexamethylene biguanide hydrochloride by titrimetric methods.
The biguanide concentration of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was measured by non-aqueous titration with HClO4, argentometric titration, the Kjeldhal method, and colloidal titration. The summation value of non-aqueous titration and argentometric titration corresponded to two titrable nitrogens in five nitrogens per one unit of PHMB-HCl, and consisted with the result of the...
متن کاملBenefit of polyhexamethylene biguanide in Fusarium keratitis.
PURPOSE To report a series of 3 patients with soft contact lens-related Fusarium keratitis. Two of them were treated with the antiamoebic polyhexamethylene biguanide 0.02% (PHMB) in combination with antifungal drugs, and 1 patient was treated with PHMB as sole antifungal regimen. METHODS Chart review of 3 patients treated with PHMB in Fusarium keratitis. Two of them were refractory to the com...
متن کاملDetermination of polyhexamethylene biguanide hydrochloride using photometric colloidal titration with crystal violet as a color indicator.
A solution of polyhexamethylene biguanide hydrochloride (PHMB-HCl) was titrated with a standard solution of potassium poly(vinyl sulfate) (PVSK) using crystal violet (CV) as an photometric indicator cation. The end point was detected by a sharp absorbance change due to an abrupt decrease in the concentration of CV. A linear relationship between the concentration of PHMB-HCl and the end-point vo...
متن کاملEvaluating a dressing impregnated with polyhexamethylene biguanide
Aims: To evaluate a new polyhexamethylene biguanide (PHMB) foam dressing for inclusion in the specialist dressing section of a trust’s wound management formulary. Methods: KendallTM AMD (Covidien) antimicrobial foam dressing’s use was reviewed through a retrospective evaluation of patients who had been treated with the dressing. Data was collected from the medical and nursing notes of 25 patien...
متن کاملPolyhexamethylene biguanide is a relevant sensitizer in wet wipes.
Polyhexamethylene biguanide (PHMB; CAS no. 2875743-3) is a preservative used as a biocide in industrial products (e.g. swimming pool disinfectants), medical devices (e.g. wound cleansers), contact lens solutions, and cosmetics such as wet wipes, deodorants, and facial cleansers. It is considered to be a rare contact allergen, with a sensitization rate of ∼0.5% in an unselected population (1, 2)...
