Macadamia oil is sometimes used in food as a frying or salad oil, and in cosmetic formulations as an emollient or fragrance fixative. The is a pale yellow almost colorless refined vegetable oil that is light, non-greasy and easy absorbed into the skin and hair shaft. It has a slight nutty flavor and one of the highest sources of essential fatty acids.

Macadamia nut oil has calcium, iron, magnesium, phosphorous, sodium, and even copper. For fatty acids it contains palmitic, stearic, palmitoleic, oleic and linoleic with palmitoleic and oleic having higher concentrations.

Macadamia oil is used in cosmetics and skin care because it is nutritive, reconstructive, and hydrating. Squalene is a naturally occurring antioxidant in Macadamia oil that helps to reduce the oxidative stress on our skin and scalp by preventing loss of moisture. The fatty acid content is the real winner for skin and hair. Those fatty acids help to add shine, strengthen, and nourish the hair follicles, which in turn fight off hair loss and brittle strands.
