Macadamia Nut oil is pressed from the nuts of the Macadamia Integrifolia tree, an evergreen that grows in Hawaii. It is an effective soap making oil that is good for all skin types, especially those with dry or mature skin.
- often used in products for facial or baby care.
- the unrefined oil is amber in color with a slightly sweet nutty odor.
- often used to treat scars, sunburns, skin irritations and small wounds.
- is slightly thicker than most carrier oils but is easily absorbed into the skin.
- contains anti-oxidents, omega-3 and omega 6 fatty acids.
- protects the skin in a similar way the human sebum does.
- acts as an effective emollient.
- has a shelf life of 6 - 12 months if refrigerated.
- produces a stable, conditioning lather is soap.
As with most exotic soap making oils, it is a little more expensive. Use a small percentage in the base oils or to superfat just before trace.

How to Cook With Macadamia Nut Oil
By Carole Vansickle
Macadamia nut oil is growing in popularity each day. This oil tastes very similar to other oils, but is far healthier than other alternatives. It is low in saturated fats, and is particularly common in "Mediterranean" diets, which are designed to be good for the heart. If you want to start using macadamia nut oil in place of vegetable or other oils, you will not make very many changes to your cooking routine.
Instruction:-
1. Start frying when the oil shimmers. Macadamia nut oil, unlike the also popular and heart-healthy olive oil, can be used hot or cold. If you are going to fry in this oil, heat the oil in the skillet until it develops a gold shimmer on the top of the oil. This lets you know that the oil is hot and ready to use to cook.
2. Spread macadamia nut oil across toasted bread to replace butter. Macadamia nut oil has many of the same taste qualities as butter. As a result, it can be used on toast or as a dip whenever you are serving bread items.
3. Use two-thirds of the measurement when replacing butter with macadamia nut oil. In many cases, you'll only need half the amount of macadamia nut oil in place of butter. However, this is not a firm measurement, so adjust the amount slightly up or down depending on the recipe. Macadamia nut oil "coats" much better than butter, so particularly when sauteing and frying, you can use half or even less of the oil than you would if you were cooking with butter.
4. Use macadamia nut oil to bake cakes that call for "liquid" fats. This means the recipe should, if possible, require melted butter or another oil rather than softened butter or shortening. You can use macadamia nut oil in place of these "solids," but the measurements are going to require a little testing to get the texture right. Start with the two-thirds mentioned above and work from there.
Notes : Macadamia nut oil is high in omega-3 fatty acids, which are good for the heart and the memory.

Oil Extraction from Nut
Many oil-bearing seeds and nuts are broken up by grinding, flaking, or rolling, then subjected to mechanical pressing to liberate the oil. The modern continuous screw press exerts pressures as high as 30,000 pounds per square inch. In modern press extraction, oilseeds or nuts are cleaned, and the shells or hulls removed; the kernels or meats are ground to a coarse meal that is pressed with or without preliminary heating. Cold-pressed oil, also called cold-drawn, or virgin, oil, is purer and has a better flavour than oil expressed with the aid of heat. After pressing the meals made from oily seeds or nuts, the remaining cake contains about 5 to 15 percent oil. Most of the oil present in these residues, and in meals made from seeds and nuts that naturally contain little oil, can be removed by extraction with volatile solvents, especially petroleum benzin (also known as petroleum ether, commercial hexane, or heptane). The solvent is percolated through the meal, dissolving the oil, which is finally recovered from the solution by evaporating the solvent. The solvent is also recovered and used over again.

Some Background of Macadamia Nut Oil - Part 1
1. As referred from Wikipedia, 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 cosmetic formulations as an emollient or fragrance fixative.
2. The following picture is the Macademia intergrifolia (buds).
3. The composition of Macadamia Nut Oil shall as the following chart:-
3. It is also informed in Wikipedia that Macadamia oil contains approximately 60% oleic acid, 19% palmitoleic acid, 1-3% Linoleic acid and 1-2% Linolenic acid. Some varieties contain roughly equal omega-6 and 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. It is also very stable due to its low polyunsaturated fat content.
4. Macadamia Nut Oil in it refined condition is is clear, lightly amber-colored with a slightly nutty odour. It is possible to refine it to complete transparency, but the faint odour of macadamia nuts remains.
