RECYCLING USED COOKING OIL FOR SOAP FORMULATION

Abstract

Oil is one of the main components in the production of soap. In this experiment, used cooking oil is being recycled back to be used for the production of soaps. The used cooking oil first need to be treated back in order to reduce its contaminants contains in the oil. The treatment process of the soap that has been used are by adsorption by using activated carbon and through filtration by using filter pump and filtration paper. The activated carbon that is used in this experiment is made of sugarcane bagasse. Based on the results, it can be seen that the colour and the odour or smell of the used cooking is reduced by this treatment process. The objective of this study is to study the efficiency of the used cooking oil to be used for the production of soap and to compare the effectiveness of the treatment process in order to reduce its contaminants. It is later found that oils with the lowest amount of contaminants produced a much quality soap then soap that is produced with the oil with high amount of contaminants. As a conclusion, used cooking oil can be recycled back to be used for the formulation of soap but treatment process is required to produce a higher quality soap.
