Abstract
Phase behavior of engkabang fat was determined through the construction of ternary phase diagrams using nonionic surfactants. Several phase regions appeared in the ternary phase diagrams such as isotropic, homogenous, liquid crystal, two phase and three phase regions. The increase of hydrophilic-lipophilic balance (HLB) values of the nonionic surfactants used gave larger isotropic and homogenous region in the ternary phase diagrams. The combination of engkabang fat:Solubilisant Gamma (2:1) in the ternary phases diagram gave an even larger isotropic and homogenous regions as well as the formation of liquid crystal region.
Kurzfassung
Das Phasenverhalten von Engkabang-Nußfett wurde durch die Darstellung ternärer Phasendiagramme mit nichtionischen Tensiden bestimmt. Einige Phasenbereiche erschienen im ternären Phasendiagramm wie isotropische, homogene Flüssigkristalle, Zweiphasen- und Dreiphasenbereiche. Eine Erhöhung der Hydrophil-Lipophil-Balance (HLB) der eingesetzten nichtionischen Tenside ergab größere isotropische und homogene Bereiche im ternären Phasendiagramm. Die Kombination von Engkabang-Nußfett:Solubilisant Gamma (2:1) ergab im ternären Phasendiagramm noch größere isotropische und homogene Bereiche sowie die Bildung eines Flüssigkristallbereiches.
