Walnut oil (Juglans regia): Very unsaturated, walnut oil presents good moisturizing, anti-aging, regenerative, emollient and toning properties. This oil is obtained from walnut kernels by cold expression and subsequent refining. Walnuts are unique among nuts because the essential fat they contain is primarily polyunsaturated (the source of omega-3 fatty acids.). Walnuts contain a host of other important vitamins and minerals. Walnut oil is a clear, grease less, penetrating oil, that is a rich source of fatty acids essential to maintaining the skin's cellular integrity. Walnut oil is not a cooking oil; high heat destroys its delicate flavor. Where it does shine is as an ingredient in a salad dressing or a fresh pasta sauce. It can be used in any cosmetic product as an active principal or as a carrier in the oily phase, without any proportion limit. Shelf life if refrigerated: at least 6 months. SAP: 189-198 INCI: Walnut (Juglans regia) oil.
