The Characterization and Testing Liquid Soap Nanoparticles of Tamarillo Extract as Antioxidants

This study aims to characterization and produce the liquid soap preparation from nanoparticles of ‘terong belanda’ extract which is very good for the antioxidants. The extraction method used here is maceration using of methanol solvent. Meanwhile, the making of technology of ‘terong belanda’ extract nanoparticles used biopolymer-based nanoparticle method. It was formulated as a liquid soap. The result of particle size analysis is extract nanoparticle for about 183,4 µm, the size of the nanoparticles in liquid soap has achieved 186.2 µm. Moreover, the result of antioxidants activity test which was conducted by the free radical scavenger method of DPPH obtained IC50 nanoparticle liquid soap preparation of 47 mg/ml, compared with scorbut acid IC50 at 49 mg/ml. Water content liquid soap nanoparticles tamarillo extract is 7,4% Besides, the results of the stability test for liquid soap nanoparticles, consisting pH 8.3- 8.6, viscosity (3928–3930 poise), Foam stability power test is 85.87 and 89%, stated there is no consistency changing of each formula. From organoleptic test, it resulted a light yellow from ‘terong belanda’ color, a characteristic soap odor and a physical condition with thick / semi-solid consistency. The last, it could be concluded from the nanoparticles liquid soap testing; there is no changing of nanoparticles size. However, it resulted a strong antioxidant power and the stability of the preparation meets the SNI requirements.
