Description

Walnut Oil is a premium, natural vegetable oil derived from the kernels of walnuts, known for its high content of polyunsaturated fatty acids, particularly linoleic acid and α-linolenic acid. This composition makes it a valuable ingredient for applications requiring a rich source of ω-3 and ω-6 fatty acids. It is sought after by manufacturers in the nutraceutical, cosmetic, and specialty food industries for its nutritional and functional properties.

Application

• Nutraceuticals & Dietary Supplements: As a carrier oil or active ingredient in softgel capsules and liquid formulations for its ω-3 fatty acid content.
• Cosmetics & Personal Care: Used in formulations for skin moisturizers, anti-aging serums, hair conditioners, and massage oils due to its emollient and skin-nourishing properties.
• Specialty Food & Gourmet Oils: Employed as a finishing oil in salads, dressings, and gourmet dishes for its distinctive, nutty flavor and aroma.
• Pharmaceuticals: Serves as an excipient in topical ointments and creams, leveraging its skin-penetration enhancement qualities.
• Aromatherapy & Carrier Oils: Acts as a base or carrier oil for diluting essential oils in therapeutic blends.
• Industrial Applications: Potential use in the manufacture of high-quality soaps, paints, and wood finishes.

Quality Control

Our Walnut Oil is produced and tested to meet stringent quality standards suitable for food, cosmetic, and nutraceutical applications. We ensure compliance with relevant specifications, including those for identity, purity, and absence of contaminants. A comprehensive Certificate of Analysis (COA) detailing parameters such as acid value, peroxide value, fatty acid profile, and heavy metals is provided with each batch to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 15-25°C (59-77°F). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation to maintain freshness and prevent rancidity. Keep away from heat and open flames.
