Walnut oil

Walnut oil (CAS 8024-09-7) is a cold-pressed or refined vegetable oil derived from Juglans regia kernels, valued across food, cosmetic, and industrial markets. Its high polyunsaturated fatty acid profile makes it a premium ingredient in both edible and technical formulations.

In food manufacturing, walnut oil is used as a finishing oil, salad dressing base, and flavor ingredient in premium culinary products where its distinct nutty character is a selling point. Personal care formulators incorporate it into facial serums and body lotions.

It is also used in hair conditioners as a skin-conditioning and moisturizing agent. In coatings, its drying oil properties make it suitable for artist-grade oil paints, wood finishes, and varnishes where film-forming performance is required.

Adhesive and sealant manufacturers may use it as a plasticizing or lubricating component in specialty formulations. Walnut oil is supplied as a clear to pale yellow liquid in drum, IBC, and bulk tanker quantities for industrial use.

Food-grade and cosmetic-grade specifications are the most commercially common, with cold-pressed variants commanding a premium in both markets. These grades ensure the oil meets necessary safety and performance benchmarks for consumers.

Refined grades are available for applications where neutral odor and extended shelf stability are priorities. This versatility allows the oil to be utilized in a wide range of manufacturing processes across various global sectors.
