THE LABORATORY PRODUCTION OF SOAP USING CAUSTIC SODA AND SODA ASH
Abstract
This study investigates the laboratory production of soap using caustic soda (sodium hydroxide) and soda ash (sodium carbonate) as key alkaline agents. The experiment aimed to analyze the saponification process, determine the effectiveness of both chemicals in soap formation, and evaluate the quality of the final product. The procedure involved preparing measured quantities of oils and fats, reacting them with controlled concentrations of caustic soda and soda ash solutions, and applying heat to facilitate saponification. Observations were made regarding texture, foaming capacity, pH levels, and cleansing efficiency. Results showed that caustic soda produced harder, more effective soap due to its stronger alkalinity, while soda ash served as a mild cleaning agent and filler, improving lathering and reducing production cost. The study concludes that combining caustic soda and soda ash in appropriate proportions enhances soap quality, stability, and usability. Recommendations include strict adherence to safety protocols and accurate measurement of reagents to ensure consistent laboratory outcomes.
