Fungicidal, Corrosive, and Mutational Effects of Polyhexamethylene Biguanide Combined with 1-Bromo-3-chloro-5,5-dimethylimidazolidine-2,4-dione.

ABSTRACT:

Background

The disinfectants polyhexamethylene biguanide (PHMB) and 1-bromo-3-chloro-5,5-dimethylimidazolidine-2,4-dione (BCDMH) each have limitations. So far, their combined usage has not been examined. In this study, the fungicidal activity of combined disinfectant using PHMB and BCDMH, named PB, against Candida albicans was evaluated.

Methods

Suspension quantitative fungicidal test and viable fungi count were used to test fungicidal effects against C. albicans. Coupon corrosion testing was used to evaluate disinfectants' corrosive effects on stainless steel, copper, and aluminum. The mouse lymphoma assay was used to detect mutations induced by PB.

Results and discussion

Fungicidal activity of the combination of 40 mg/L PHMB and 40 mg/L BCDMH was compa
