'''Macadamia oil''' (or '''Macadamia nut oil''') is the non-volatile oil expressed from the nut meat of the [[macadamia]] (''Macadamia integrifolia'') tree. Macadamia oil is sometimes used in [[food]] as a frying or salad oil, and in [[cosmetics|cosmetic]] formulations as an [[emollient]] or [[fragrance fixative]].
== Chemical structure ==
Macadamia oil contains approximately 60% [[oleic acid]], 19% [[palmitoleic acid]], 2.8% [[Linoleic acid]] and 1% [[Linolenic acid]]. It also contains 3% [[omega-6]] and 3% [[omega-3]]. Although macadamia is cultivated in many different parts of the world, the oil's fatty acid profile is not greatly influenced by environmental factors. The oil displays chemical properties typical of a vegetable triglyceride oil.
== Physical properties ==
Macadamia oil is liquid at room temperature. The refined oil is clear, lightly amber-colored with a slightly nutty odour.
== Uses in Food ==
Macadamia oil is an excellent frying oil due to its high heat capacity.
Several properties of macadamia oil are particularly important for use as an edible oil:
* It contains up to 85% [[monounsaturated fat]]s,
* has an unrefrigerated [[shelf life]] of one to two years, and
* a [[smoke point]] of 410°F.<ref>{{cite web|url=http://www.macnutoil.com/|title=Mac Nut Oil}}</ref>
== Uses in Cosmetics ==
Macadamia oil's rich, cushiony skinfeel and high oxidative stability make it especially suitable for heavy creams and suncare formulations.<ref>{{cite web|url=http://www.botanical.com/products/learn/oilprofile/macadamia.html|title=Botanical.com Macadamia Nut Oil profile and information}}</ref> Derivatives of Macadamia oil in cosmetics include the light emollient [[Ethyl Macadamiate]] and water soluble [[PEG-16 Macadamia Glycerides]].
Macadamia oil is an excellent botanical replacement for [[mink oil]] in most applications.
Macadamia oil's [[INCI name]] is ''Macadamia Integrifolia Seed Oil''.
