What is "Macadamia Ternifolia Seed Oil" and what is its utility?

Known by its INCI (International Nomenclature of Cosmetic Ingredients) name Macadamia Ternifolia Seed Oil, this ingredient is also commonly referred to as macadamia nut oil. Of plant origin, it is compatible with organic skincare products.

As its name suggests, macadamia nut oil is extracted from macadamia nuts. These are the fruit of the macadamia tree, which originates from Australia, but is now found in the South Pacific region and South Africa. This evergreen tree is primarily cultivated for its nut-like fruits, which are similar to chestnuts.

Macadamia nut oil is obtained through cold pressing, meaning it is processed under a temperature of 60% or less. This mechanical process is carried out without the use of solvents. In fact, the whole shells are dried and then crushed. They are placed in cloth bags before being cold-pressed with the aim of obtaining crude oil. No refining treatment is necessary.

Unlike other vegetable oils, macadamia nut oil stands out due to its high content of palmitoleic acid, an ingredient primarily found in animal fats. As a result, macadamia nut oil can easily replace mink oil derived from the subcutaneous fat of minks. In the field of cosmetology, macadamia nut oil is among the ingredients chosen for creating massage oils. Indeed, it is easy to spread and readily penetrates the skin.

Macadamia nut oil is incorporated into emollient skincare products. It contributes to the softening and relaxation of skin tissues, which reduces dryness and dehydration. Moreover, this ingredient is also used to formulate moisturizing treatments. It softens the skin surface and promotes cellular regeneration, particularly in dry, chapped, and/or sensitive skin. When combined with other ingredients, macadamia ternifloria seed oil also acts as a skin conditioning agent.

Rich in unsaturated fatty acids, macadamia nut oil contributes to the elasticity and suppleness of the skin. Due to its nourishing properties, this ingredient softens and soothes the skin. As it penetrates the skin layers quite quickly, it leaves no greasy film upon application. Macadamia nut oil contains a high concentration of oleic acid and palmitoleic acid , which facilitate skin healing. Therefore, it is recommended for sensitive, acne-prone, or damaged skin.

Skincare products containing macadamia oil are also used to diminish stretch marks or cracks on the skin. Due to its strengths, this ingredient is included in the formulation of night face creams, eye contour serums, moisturizing oils for the body and face, lip balms, or hair oils.
