This study is motivated by the improper disposal of Waste Cooking Oil (WCO), affecting the aquatic ecosystem. Recycle to make a product like soap is one of the approaches to solve this issue. Soap productions consist of three processes which are filtration WCO, saponification, and solidifying process. Solidifying process is indeed taking a lot of time. Therefore, this study aims to develop a soap waste cooking oil based (SWOB) with beeswax
and palm wax to speed up the solidification process. An improvement is observed at 65% for the hardening process compared to SWOB without adding palm wax and beeswax. A combination of WCO, beeswax, and palm wax, A combination of WCO, beeswax, and palm wax, is an excellent choice to be used in the superb choice for soaps making as they are an environmentally safe organic material.
