Production of Solid Soap with Addition of Green Betal Leave (Piper Betle L.) Extract and Left Lemon Extract(Cymbopogon Nardus L. Rendle) As Antioxidants

Abstract

Soap is one type of surfactant made from natural oils or fats. The saponification procedure produces soap. Soap serves to emulsify dirt in the form of oil or other impurities. Many soaps sold in the market use synthetic additives as antioxidants that can interfere with skin health for those with sensitive skin. The scarcity of soap that uses antioxidants causes the high price of soap that contains antioxidants. This problem can be solved by using existing natural resources such as using green betel leaves and citronella and producing natural antioxidant-dense soap. This study aims to determine the composition of palm oil, olive oil, and virgin coconut oil (VCO) on the quality of making solid soap and obtain variations of solid soap with green betel leaf extract and citronella by the Indonesian National Standard (SNI) 06-3532-1994. The method used is by varying the oil, green betel leaf extract, and citronella. Product analysis includes pH, water content, free alkali, free fatty acid, mineral oil, bacterial test, and organoleptic test. The natural antioxidant of the soap products obtained good results from a mixture of palm oil, VCO oil, and olive oil in a ratio of 1: 2: 2.
