Macadamia integrifolia: This tree is native to Australia. Also known as Queensland nut oil, this cold pressed oil is high in palmitoleic acid, a monounsaturated fatty acid that acts as an antioxidant, preventing deterioration of cell membranes. For mature skin it is hydrating and gentle. It is a skin lubricant and is easily absorbed by the skin, sometimes described as a “vanishing oil”. Helpful in cases of sunburn and wound healing. This oil has a long shelf life and good resistance to rancidity. It also has a mild laxative action. Macadamia nut oil contains about 80% monounsaturated fatty acids and a higher percentage of palmitoleic acid than other vegetable oils. Palmitoleic acid does not occur in any other plant oil. SAP value: 195.0. INCI: Macadamia integrifolia (Macadamia nut) seed oil.

At 3%, macadamia oil is the lowest of all culinary oils in polyunsaturated Omega 6 fatty acids (olive oil=8%, canola=23%). Excessive Omega 6 Fatty Acids may have an adverse impact on blood clotting, immune function & inflammation. Monounsaturates tend to lower LDL (bad) cholesterol levels but do not change HDL (good) cholesterol levels. Polyunsaturates lower both. Macadamia oil is 55-67% oleic acid. Oleic acid apparently increases the incorporation of omega-3 fatty acids into cell membranes. This oil is low in saturated fat (approximately 14%, of which roughly 26% is benign Stearic acid). Because of its high smoke point and monounsaturated level, Macadamia oil is least likely to develop the unhealthful trans fatty acids and lipid peroxides when heated. Can be used for stir-fry because of its very high smoke point 410ºF. (Depending on quality and age, olive oil breaks down at less than 325°̊). Macadamia oil has a very long shelf life due to the high natural levels of monounsaturates (that limit the points where oxygen can attack) and antioxidants (that restrict oxidation).
