Product Description
Premium Oil Plant Raw Materials – Palmitoleic Acid (Omega-7) and Polyphenols for Cardiovascular Health and Skincare
Product Description
For cardiovascular health and high-end skincare products, formulators need natural oil raw materials with excellent fatty acid composition and good stability. Macadamia nuts, rich in oleic acid, palmitoleic acid (omega-7), and polyphenols, are versatile ingredients suitable for both oral health supplements and topical skincare.
Macadamia Extract is characterized by palmitoleic acid (omega-7) and polyphenolic components, derived from the seeds of Macadamia integrifolia of the Proteaceae family. It is produced into standardized concentrated powder through cold pressing and refining processes, with polyphenol content ranging from 10% to 20%. Its fatty acid composition is mainly oleic acid, rich in palmitoleic acid, easily absorbed, non-greasy, and a high-quality oil ingredient for cardiovascular health and premium skincare formulations.
Macadamia nuts are important raw materials for high-end edible nuts and skincare oils, with the cultivation industry developing rapidly in Yunnan, China. The global market demand is broad.

Plant Material Introduction
The raw material is the dried seeds of the Macadamia integrifolia, a plant of the Proteaceae family. Mainly produced in Queensland, Australia, Hawaii, as well as Yunnan and Guangxi in China. Macadamia nuts are rich in unsaturated fatty acids.
Core Benefits
The following summary of benefits is based on published scientific research and traditional applications; specific benefits should be evaluated in combination with product form and dosage.
Macadamia nut extract has a substantial research basis in cardiovascular health and skin care. Its richness in monounsaturated fatty acids (oleic acid, approximately 55%-75%) has been shown in related studies to support the maintenance of healthy blood lipid levels; its characteristic fatty acid palmitoleic acid (omega-7) has also been studied in relation to skin barrier function and liver health. In terms of skin care, macadamia nut oil is easily absorbed and highly moisturizing.
In vitro studies show it can enhance skin hydration and reduce transepidermal water loss (TEWL); its plant sterols exert anti-inflammatory activity by inhibiting the expression of inflammatory factors. The above results are mainly based on in vitro and clinical literature, and practical application requires comprehensive evaluation considering the formulation and dosage.
