The Effect of Variations of Coconut Oil and Palm Oil on the Characteristics of Soap Bars Containing 7% Concentration of Moringa Oleifera Oil

Abstract

Soap is one of the cosmetic products used for skin care. Natural soaps are beginning to be embraced by society. In this research, a formulation of natural soap bars containing moringa oil (Moringa oleifera) with coconut oil, palm oil, and olive oil as a base was made. This study aimed to determine the effect of variations of different coconut oil : palm oil ratio combinations (31% : 34%, 29% : 36%, 27% : 38%) on the physico-chemical characteristics (organoleptic, pH, foam stability, moisture content, hardness and free alkaline or fatty acids) of oat scrub soap bars containing 7% moringa oil. The data were analyzed using one way ANOVA. The results showed that there was a significant effect of variations of coconut oil and palm oil combinations on the following characteristics of the oat scrub soap bars: hardness, moisture content, foam stability and free fatty acids. Based on the physico-chemical characteristics of formula I to formula III, these formulations fulfill the requirements according to SNI 3532:2016, and so can be made into commercial soap bars.
