Formulation of Solid Soap of Kaolin Clay Using Sucrose Ester

Abstract

Abstract Kaolin solid soap is one of the soaps that can be used to remove heavy dirt (Najis mughalladzah). Sucrose esters are a unique group of emulsifiers that are non-ionic surfactants and completely biodegradable. They are obtained by the transesterification of methyl ester with sucrose. This research aims to obtain the best concentration of sucrose ester and kaolin clay and to know the characteristics and quality of soil soap. Soap was made by finding the suitable concentration for the ingredients used to make soap based on Islamic Sharia law, where the amount of soil based on the edict (fatwa) of the Ulama Council is a minimum of 5 In this study, variations in the concentration of sucrose ester used were 2, 4, and 6%, while the concentrations of kaolin clay were 20, 25, and 30%. This research used a completely randomized design (CRD) with nine treatments and three replications. Observations of the soil soap bar include pH, foam test, hardness level, moisture content, free fatty acids, and organoleptic tests. The best formulation of soil soap based on organoleptic test results is soap with a concentration of 25% kaolin and 4% sucrose ester.
