Ds. Jones et al., PHYSICAL FACTORS AFFECTING THE SPORICIDAL ACTIVITY OF CHLORHEXIDINE GLUCONATE, International journal of pharmaceutics, 119(2), 1995, pp. 247-250
The effects of pH and indirect ultrasonication on the cidal activity o
f aqueous and alcoholic solutions of chlorhexidine gluconate against B
acillus subtilis spores were examined. At moderately elevated temperat
ures, increasing pH enhanced sporicidal activity. pH markedly enhanced
the sporicidal activity between indirect ultrasound and chlorhexidine
. 'Alcoholic' chlorhexidine gluconate was more sporicidal than its aqu
eous counterpart.
