Comparative Studies in the Release of Sodium and Potassium Ions by Indigenous Black Soaps from some Selected Skin Pathogens

The indigenous black soap possesses antimicrobial activities with varying mechanisms of action. In the present study, the comparative release of sodium and potassium ions from clinical isolates: Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, Trichophyton rubrum and Candida albicans by three different indigenous black soaps were investigated by flame photometry method. The black soaps were subjected to qualitative and quantitative screening for phytochemical using standard methods. Sodium ion was leaked to a value of 833 ppm for S. aureus while potassium ion to a value of 20 ppm for T. rubrum. Qualitative and quantitative screening for phytochemicals showed saponin was the highest with values between 20.50-33.31 mg gG while tannin the lowest between 1.05-2.05 mg gG across the black soap samples. This study has posited that the antimicrobial activities of the black soap may be attributed to its phytochemicals and that the soap has lytic effect on the pathogens.
