Abstract
Purpose
This study investigated physicochemical properties and antimicrobial performance of soaps formulated from natural ingredients with the intention to apply them as alternative deodorizing soaps in personal care products.
Methods
Soaps were formulated with natural ingredients including lemon, aloe vera and honey. Foam stability and capacity tests as well as pH were determined for the soaps. Deodorizing effectiveness of the soaps was tested theoretically using minimum inhibitory concentration (MIC) test by screening them against pathogenic organisms causing body odour: bacteria (Staphylococcus aureus, Candida albican, Staphylococcus hominis, Strephotococcus mutant, Staphylococcus epidemidis) and fungi (Tinnea annum, Tinneapedis and Trycrophyton rubrum) using agar well diffusion method and poisoned food technique respectively while having Dettol soap and ketoconazole as controls.
Results
The soaps had a maximum foam capacity of 150% and foam stability of 100% with pH values in the range of 9.3–9.8 and inhibited the growth of the tested organisms for up to 6 days at 0.1 g/ml concentration.
Conclusion
The soaps are mildly alkaline, possess good foaming capacity and stability and have considerably significant antimicrobial properties that can impede the growth of the organisms.
