Formulation of moringa soap as an antioxidant to protect free radicals on the skin

The preparation of bath bar soap can be used to clean the skin from dirt, and can be useful as antioxidant that can protect the skin from free radicals. This study aims to determine whether a solid soap formulation from ethanol extract of Moringa leaves could meet the physical characteristics of the soap and the test of antioxidant activity. The research design used was experimental laboratory. Moringa leaves ethanol extract obtained by soxhletation method with 96% ethanol solvent. The extract then formulated in 5 bar soap formulations with various concentrations of Moringa extract were FI (0g); FII (1g); FIII (2g); FIV (3g); FV(4g). Bath bar soap would be tested for the characterization of the soap, namely organoleptic, water content, amount of free alkali, pH and ethanol insoluble material according to the requirements of the Indonesian National Standard 3532:2021. Antioxidant activity of bath bar soap would be tested by the DPPH reduction method. The results of the physical quality showed that the Moringa extract bar soap had organoleptic of solid, brownish green in color, had uniform homogeneity, the pH value was qualified the requirements of SNI, the water content was qualified the requirements of SNI, the stability of the FI-FIV foam was qualified the requirements, the ethanol insoluble material FI, FII, FIV were not qualified the requirements. Requirements, for testing the free alkali content of FIII was qualified the requirements of SNI. The bath bar soap of moringa extract showed an weak antioxidant activity
