The high content of triglycerides in tallow can be utilized as raw bath soap with the saponification process. Temu ireng extract can be considered as fillers to the soap, because temu ireng extract countains higher total phenolic so that temu ireng can be acted as an antioxidants agent in the soap. The objective of this research was to study the characteristics of bath soap that made from different composition of tallow and extract temu ireng. Soap with A, B, and C formulation met the qualification with the SNI 06-3532-1994 in water content, the amount of fatty acid, and free alkaline, but did not to the amount of unsaponification fat. Soap with A, B, and C formula significantly affected the amount of fatty acids, pH value, unsaponifiable fat,and DPPH scavenging activity. The result of hedonic quality test from A, B, and C formula affected the intensity of color, temu ireng aroma, fatty aroma and foaming power significantly. DPPH scavenging activity had highest activity at 24.01% of C formula soap with antioxidant capacity of 73.47 mg EVC per 100 g and the amount of total phenolic was 17.32 mg GAE per 100 g.
