About MACADAMIA INTEGRIFOLIA SEED OIL

Macadamia nut oil — uniquely rich in palmitoleic acid, which closely mimics skin's own sebum. Excellent for dry and mature skin. Non-irritating.

Detailed Analysis

Macadamia Integrifolia Seed Oil (CAS 438545-25-6) is cold-pressed from macadamia nuts and is distinguished by its high palmitoleic acid content (15-25%), an omega-7 fatty acid that decreases in human sebum with age. Also contains oleic acid (55-67%) and phytosterols. Its fatty acid profile closely mimics human skin lipids, making it exceptionally well-absorbed. Non-comedogenic (rating 2) and suitable for sensitive skin. Provides antioxidant protection via squalene and tocopherols.
