Therefore soap is undoubtedly the oldest product to be produced specifically as a surfactant and in its many forms continues to play a major role today. Through the ages the soap industry developed and changed and nowadays this highly competitive marketplace soap is presented in a multitude of forms both solid and liquid. Traditional and essential task of soap is to wash and clean and stain removal. The increasing demands of the cosmetics market made that modern soap products are normally enhanced with additional raw materials e.g. moisturizing. Modern soap formulations are also used to create antibacterial variants which can be considered more effective. The main aim of this work was to determine the antimicrobial properties of liquid soap with declared antibacterial activity. The comparison between these properties of antibacterial and regular soaps was also investigated. Antimicrobial activity of soaps and their aqueous solutions were investigated using filter-paper disc diffusion method or well diffusion assay. Results obtained indicate that all examined soaps demonstrated antagonistic activity against microorganism investigated. Key words: liquid soap, antimicrobial activity |
