Abstract
The technology of nanoparticles is a formulating technology of a particle which dispersed on the nanometer size or scale per thousand microns. This study aims to characteruization 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 um, the size of the nanoparticles in liquid soap has achieved 186,2 um. 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 ug/ml, compared with scorbut acid IC50 at 49 ug/ml. Besides, the results of the stability test for liquid soap nanoparticles, consisting pH (4,5-6), viscosity (3928 - 3930 poise), dispersibility (6-7 cm), 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.
