The Process of Making Antibacterial Solid Soap with the Addition of Sugarcane Bagasse Activated Carbon

Abstract

This invention concerns the process of making antibacterial solid soap by adding bagasse activated carbon using the hot process method. The process includes heating vegetable oil to approximately 70°C, adding 15% NaOH solution to initiate the saponification reaction, adding a mixture of glycerin, sugar, and surfactant that has been dissolved in hot water, and stirring at a speed of approximately 120 rpm. Next, 96% ethanol is added at ±20% until the mixture becomes transparent, then cooled to a temperature of 40–55°C before adding bagasse activated carbon in a concentration of 1–3% by weight of the total soap. The activated carbon has a water content of ≤10%, ash content of ≤10%, and a methylene blue adsorption capacity of 400–500 mg / g. The mixture is molded and left for ±24 hours to obtain a solid soap with a homogeneous distribution of activated carbon, good physical stability, and strong antibacterial activity against gram-positive and gram-negative bacteria.
