Physicochemical characteristics and thermal stability of Jordanian jojoba oil

  • Published:
Journal of the American Oil Chemists' Society

Abstract

Viscosity, flash point, refractive index, viscosity index, specific gravity, aniline point, foam testing, color stability, ash content, water content, saponification value, iodine value, and other properties were investigated for Jordanian jojoba oil. Results showed that jojoba oil has low ash and water contents and high flash point and viscosity index. Viscosity and specific gravity changed only slightly with temperatures. As an additive, jojoba oil improved the viscosity index of lubricants from 100 to 130. When subjected to heating and cooling from 40 to 200°C, the chemical structure, kinematic viscosity, and refractive index remained almost constant. Thus, jojoba oil was highly stable in this temperature range.
