Stability Evaluations of Different Types of Vegetable Oil-based Emulsions

Abstract

inflammatory 5 and antioxidant 6 properties. Therefore, it is suitable to be used in food, pharmaceutical and cosmetic industries. Soybean oil SBO is extracted from Glycine max seeds Fabaceae. It is a popular edible oil used in baking, salad dressing and cooking. It contains high percentage of essential fatty acids, polyunsaturated fatty acids and minor constituents, such as vitamins, isoflavones, tocotrienols and phytosterols. Previous studies showed that it possessed extensive medicinal properties, including antioxidant 7 and anti-microbial, as well as protecting cell membranes from damage and infections 8. In addition, sunflower seed oil SFO contains predominantly polyunsaturated fatty acids and has been widely used as a cooking oil. It is notably rich in vitamin E and contains minor compounds such as phytosterols, polyphenolics, squalene and hydrocarbons. Vitamin E in SFO contributes to its antimicrobial 9, 10 effect. Lastly, safflower oil SAF is a vegetable oil extracted from the seeds of Carthamus tinctorius. It has similar nutritional values with SFO and usually used as salad dressing, cooking oil and cosmetic products. Previous studies indicated that SAF shows anti-fungal 11 and anti-inflammatory 12 properties. Many homemade emulsions are made up of different vegetable oils due to their beneficial properties that have Abstract: The study was aimed at evaluating the effects of vegetable oils on emulsion stability. Palm olein (POo), olive oil (OO), safflower oil (SAF), grape seed oil (GSO), soybean oil (SBO) and sunflower oil (SFO) with different degree of saturation levels were chosen as major ingredient of oil phases. All the emulsions were stored at 4℃, 27℃ and 40℃ for 35 days and subjected to all the stability tests, including temperature variation, centrifuge test, cycle test, pH and slip melting point. The results indicated that POo exhibited the highest stability, followed by SAF, OO, GSO, SFO and SBO. In addition, the results implied that the degree of saturation levels of vegetable oils does give significant effect on emulsion stability based on the centrifuge testing for an approximate 30% usage level of oil. The POo-based emulsion exhibited good emulsion stability throughout the experimental period indicated that POo could be a good carrier oil for various applications in cosmetic industry.

“…Palm olein (POo), olive oil (OO), safflower oil (SAF), grape seed oil (GSO), soybean oil (SBO) and sunflower oil (SFO), which have different saturation levels, are the main oils in the stability evaluation study of various vegetable oil‐based emulsions. As a result, it was confirmed that the saturation level of the vegetable oil had a significant effect on the emulsion stability 30 …”

“…As a result, it was confirmed that the saturation level of the vegetable oil had a significant effect on the emulsion stability. 30 There is a study result that Korean red ginseng hot water extract relieved atopic dermatitis-like inflammatory response by negative regulation of the mitogen-activated protein kinase (MAPK) signaling pathway in vivo.…”

Palm-Pressed Mesocarp Fibre Oil as an Alternative Carrier Oil in Emulsion

“…In this case, the formulation becomes less stable when subjected to centrifugal force. Literature data showed that creaming was observed in vegetable oils including olive, safflower, grape seed, soy bean and sunflower oils-based emulsions that kept at 40 after a 14-day of the experimental period 23 . The data postulates that the stability of PPFObased emulsion is superior to the vegetable oil-based emulsions though the performance of PPFO-based emulsion is a little poor compared to that of PO-based emulsion.…”

“…The emulsions were prepared according to Teh et al 2018 23 . In brief, oil-soluble ingredients, stearic acid 20 g , cetyl alcohol 20 g and glycerol monolaurate 30 g were first added into 300 g of PPFO, then mixed and heated at 70 until fully dissolved.…”

“…Our aim was to evaluate the stability of PPFO in an oil-based formulation attempted as a personal care ingredient. Palm oil and its derivatives are widely used in cosmetic and personal care industries and literature data showed that palm olein-based emulsion exhibited good emulsion stability 23 , therefore palm olein PO was used as a control in this study for comparison purpose.…”
