Synthesis of antioxidant liquid soap from pandan leaf extract (Pandanus amaryllifolius Roxb.) and cocamide-dea

Exposure to UV rays can form free radicals, which will cause progressive damage to the skin's cellular structure, resulting in accelerated aging. The antioxidants contained in pandan leaves can capture free radicals and reduce their adverse effects. This study aims to determine the correct formula for antioxidant liquid soap by adding pandan leaf extract. The antioxidant liquid soap formula was made using four variations of cocamide-DEA concentrations, namely 2%, 4%, 6%, and 8%, and three concentrations of pandan leaf extract (Pandanus amaryllifolius Roxb.), namely 20%, 30%, and 40%. The extract was made using the maceration method with 96% ethanol solvent. Soap formulations are tested using free alkali, fatty acid, and water content tests. The results of observations of the antioxidant liquid soap formula with pandan leaf extract and the addition of cocamide-DEA have good physical quality and stability and meet standards.
