Application of Mono-Diacyl Glycerol from Palm Oil By Product as Emulsifier for Body scrub

Abstract

Mono-diacyl glycerol (M-DAG) widely used as food emulsifier, where in this study was produced through esterification of palm fatty acid distillate (PFAD) and glycerol from biodiesel by product. This research aimed to found the best formulation of the purified M-DAG on body scrub and identify physical characteristics of the product. This study is divided into two stages. First, is the selection of the preferred body scrub formulation based on the color, homogeneity, impression in the skin, the ability to remove dead skin’s cells and viscosity through the hedonic test. The selected formula then treated by M-DAG concentration (4%, 4.5%, 5%) and the type of scrub (rice, oat, PE20) at the second stage. Different concentrations of M-DAG give significant influence on density of body scrub but not for pH. While different types of scrub give significant influence on pH and density. Different concentration of M-DAG affect the size of emulsion globula. When the higher concentration used, the smaller globulas are formed. Body scrub with MDAG addition is stable at -4° C and 45° C and no heavy metals (Hg, Pb, As) were detected in the product. Based on the hedonic test towards parameters of texture, viscosity, and the ability to remove dead skin cells, it is known that 5% MDAG + PE20 formula has the highest preference level from panelist.
