Evaluation of basic properties of jojoba oil for confirming the suitability for use in cosmetic products

Abstract

Golden liquid wax reserved in the seeds of Simmondsia chinensis (Link) Schneid (common name: Jojoba), the only species of family Simmondsiaceae, has chemical and rheological properties resembling to those of sperm whale oil. The purpose of this study was to evaluate the physicochemical properties of jojoba oil. The basic properties of jojoba oil included rheological properties, surface tension, spread ability, pour point, cloud point, acid value, peroxide value and saponification value. Viscosity of jojoba oil was found to be 5.37 ±0.05 mPas.Sec. Surface tension, spread ability, pour point, cloud point, acid value, peroxide and saponification values were 49.00 ±0.33 m N/m, 7±0.2 mm, 4.2±0.5ºC, 9.7±0.5⁰C, 0.561 mg/g KOH, 0.87 meq/Kg, 84.15 mg / g KOH, respectively. All evaluated properties of jojoba oil confirmed its safety and suitability for further use in cosmetic products.
