Macadamia Integrifolia Seed Oil
What is Macadamia Integrifolia Seed Oil?
Macadamia integrifolia seed oil is derived from the kernels of the macadamia nut tree, originally from Australia and now cultivated in various regions. This lightweight, non-greasy oil is obtained through cold-pressing the seeds, yielding a composition dominated by monounsaturated fatty acids such as oleic and palmitoleic acids, along with smaller amounts of stearic and linoleic acids. In cosmetics, it serves primarily as an emollient and skin-conditioning agent in formulations like moisturizers, facial oils, and hair care products. It works by spreading evenly on the skin to create an occlusive barrier that reduces transepidermal water loss while allowing the skin to breathe. The oil's similarity to human sebum promotes quick absorption, enhancing skin suppleness. Additionally, its tocopherol content contributes to stability against oxidation, supporting product integrity and skin protection from free radicals.
