Science

Mechanism of Action

This ingredient functions by two primary mechanisms. As an emollient, it effectively softens and smooths the skin, improving its overall feel. As a surfactant, it acts as an emulsifier, enabling the creation of stable, uniform mixtures of oil and water, which is crucial for cosmetic formulation consistency. The macadamia oil component itself is rich in monounsaturated fatty acids, notably oleic and palmitoleic acids, which closely resemble the skin's natural sebum. This composition allows it to fortify the skin's hydrolipidic film, thereby maintaining hydration and providing nourishment. Furthermore, it contains antioxidants such as phytosterols and tocopherols (Vitamin E) that help safeguard skin cells from damage caused by free radicals. Known for its regenerative, restructuring, and soothing properties, it actively contributes to skin barrier repair.

Stability

As an emulsifying agent, this ingredient significantly enhances the stability of emulsions. Its production involves the transesterification of polyglycerin-6 with macadamia seed oil, a process that requires precise control of reaction conditions to ensure stable and effective esters. The foundational macadamia nut oil should be stored in well-sealed, full containers or under an inert gas, protected from light, in a cool, dry environment.
