Abstract

ABSTRACTMoringa oleifera oil with comparable caprylic triglyceride to Lexol® 865 and higher oleic acid was prepared into microemulsions. A system comprising natural and synthetic oils (Omix), surfactant (Tween 80 and Span 80; Smix), and water was microemulsion prepared by a visual grading. Twelve microemulsions with diameter of 83.75–286.76 nm, pH of 6.75–8.23, and viscosity of 280.00–517.20 mPa•s were produced. Their antioxidant were 0.926–2.921 μg Trolox/mg. Microemulsions with Omix:Smix mass ratio of 2:8 and 5:5 that had Omix of 2:1 and 1:1 were stable following a 4 months stability evaluation at 25°C and 45ºC. Microemulsions containing moringa oil produced by a practical low-energy method exhibited good viscosity with an acceptable pH and antioxidant activity were therefore applicable for further applications.
