Hydrogenated Macadamia Seed Oil
What is Hydrogenated Macadamia Seed Oil?
Hydrogenated Macadamia Seed Oil comes from the seeds of Macadamia integrifolia or related trees, where the natural oil—rich in monounsaturated fatty acids like oleic and palmitoleic—is hydrogenated to add hydrogen atoms to its double bonds. This creates a more saturated, stable fat with a firmer consistency and better resistance to rancidity. In cosmetics, it serves as an emollient and conditioning agent in lotions, creams, and hair care products. It works by spreading evenly over the skin or hair, filling in micro-irregularities to enhance smoothness, lubricity, and barrier function, which helps limit water evaporation. Its sebum-like profile allows non-greasy absorption, while in hair formulations, it minimizes tangles and static by coating cuticles.
