What is Macadamia Ternifolia Seed Oil?
Macadamia Ternifolia Seed Oil is a luxurious fixed oil derived from the nuts of the Macadamia ternifolia tree, commonly known as the Bushnut. This tree belongs to the Proteaceae family and is native to Australia. The oil is primarily composed of the glycerides of fatty acids, which include a high concentration of monounsaturated fats, such as oleic acid and palmitoleic acid. These fatty acids are known for their moisturizing and skin-conditioning properties, making the oil a popular ingredient in cosmetic formulations.
The history of Macadamia Ternifolia Seed Oil in cosmetics is relatively recent, although the macadamia nut itself has been a staple in the diets of Indigenous Australians for centuries. The oil began to gain attention in the beauty industry in the late 20th century, as consumers and manufacturers alike started to seek out natural and plant-based ingredients for skincare products. Its unique fatty acid profile, which closely resembles the natural oils found in human skin, made it an attractive option for emollient purposes.
The production of Macadamia Ternifolia Seed Oil involves several steps. First, the nuts are harvested from the macadamia trees and then dried to reduce moisture content. Once dried, the nuts are cracked open to extract the kernels, which are then cold-pressed to obtain the oil. Cold pressing is a mechanical extraction method that does not involve heat or chemical solvents, ensuring that the oil retains its beneficial properties. The resulting oil is then filtered and sometimes refined to remove impurities, making it suitable for use in various cosmetic products.
The Benefits/Uses of Macadamia Ternifolia Seed Oil

Emollient Properties
Macadamia Ternifolia Seed Oil is primarily known for its emollient properties. In simple terms, an emollient is a substance that helps to soften and smooth the skin. When you apply a product containing this oil, it forms a protective layer on the skin’s surface, which helps to lock in moisture. This can be particularly beneficial for those with dry or flaky skin, as it helps to keep the skin hydrated and supple. By maintaining the skin’s moisture balance, it can also contribute to a healthier and more youthful appearance.
