Studies on boundary lubrication properties of oxidised coconut and soy bean oils

Abstract: Vegetable oils are a potential source of base oils for biodegradable lubricants, with limited oxidative stability. This study focuses on the effect of long-term ageing and the infl uence of oxidation products on the boundary lubrication performance of coconut and soy bean oils, by subjecting them to accelerated ageing in a dark oven at elevated temperature. The samples were collected at regular intervals and analysed for the changes in viscosity, percentage of free fatty acid and peroxide number compared to fr… Show more

“…It can be seen that an increase in kinematic viscosity was observed with usage of the oil in the engine. This is basically because of the oxidation of the oil samples 30) . It was also noticed that the lubricant was contaminated with fuel during use.…”

“…Coconut oil with more than 90% saturated fatty acids is known to be non-toxic to aquatic system. Higher percentage of saturation in coconut oil ensures higher stability to thermal degradation and oxidative degradation of oil [29]. Being highly resistant to oxidative depletion, coconut oil produces least amount of oxides and peroxides, which could otherwise be toxic to living beings.…”

“…Data on the quality of other raw materials used in topical skin-care formulations are available in the literature (Kumar & Krishna, 2015;Mannekote & Kailas, 2009;Thanonkaew et al, 2015). However, the quality may vary widely depending on the manufacturing process.…”
