Polyhexamethylene biguanide hydrochloride (PHMB-HCl) is widely used as a disinfectant in personal care products such as cosmetics and toiletries and as a sanitizer in swimming pools. PHMB-HCl possesses marked characteristics of cationic polyelectrolytes. We have applied unique determination methods to PHMB-HCl using its ion association with organic anions and polyanion. In this review, we provide several colloidal titrations and a voltammetric method.
