Potassium and sodium fatty acid salts as an alkali soap are a type of surfactant potentially used for their antibacterial activity. Traditionally, this material is prepared from triglyceride oil with potassium or sodium hydroxide through a saponification reaction. The research synthesized potassium fatty acids salt (potassium soap, K-soap) from olive oil and examined the antibacterial activity. Potassium soap was prepared by reacting olive oil with potassium hydroxide through the saponification reaction. Properties of the as-synthesized soap are a yellowish-white solid, melting point of 200-204 ℃, and soluble in water, methanol, and ethanol. Antibacterial activity against Staphylococcus aureus and Escherichia coli with MIC < 1% indicated that it possessed great potential as antibacterial agent. © 2022 American Institute of Physics Inc..
