Hazelnut Oil
Hazelnut Oil
Hazelnut Oil is a plant-based fixed oil extracted from the kernels of hazelnuts. It is widely used in skincare, cosmetics, massage oils, hair care products and selected food applications. Known for its smooth texture and distinctive fatty acid profile, Hazelnut Oil is a valued ingredient in personal care and specialty oil formulations.
The oil generally contains oleic acid as its predominant fatty acid, along with linoleic acid and other fatty acids. It may also contain naturally occurring minor components, including vitamin E compounds, depending on the source and processing method.
Hazelnut Oil is available in different grades, including food-grade and cosmetic-grade products. Its suitability depends on quality specifications, processing and the intended application.
What Is Hazelnut Oil?
Hazelnut Oil is a fixed vegetable oil obtained from the kernels of hazelnuts, most commonly from Corylus avellana. It can be produced through mechanical pressing, including cold pressing, or other suitable extraction methods.
The oil is used as an ingredient in cosmetic formulations because of its emollient properties and is also used in certain culinary applications when manufactured to the appropriate food-grade standards.

How Is Hazelnut Oil Extracted?
1. Selection of Hazelnuts
Suitable hazelnuts are selected according to quality requirements. The nuts are inspected to identify damaged kernels and remove unwanted materials.
2. Kernel Preparation
The shells are removed to obtain the kernels. Depending on the production process, the kernels may be cleaned and prepared before oil extraction.
3. Oil Extraction
Hazelnut Oil may be obtained through mechanical pressing. Cold pressing is used when the production process is designed to limit external heat during extraction. Other extraction methods may be used for specific commercial grades.
4. Filtration and Refining
After extraction, the oil may be filtered to remove suspended particles. Depending on the intended use, further processing or refining may be carried out to achieve the required colour, odour and consistency.
5. Quality Testing and Packaging
The finished oil is evaluated against relevant quality specifications. Testing may include fatty acid composition, acid value, peroxide value, moisture and other parameters. Suitable packaging helps protect the oil from light, heat and oxygen.
Uses and Applications of Hazelnut Oil
1. Skincare Products
Hazelnut Oil is used in a variety of skincare formulations, including creams, lotions, facial oils and moisturisers. Its emollient properties help condition the skin and contribute to the feel of the finished product.
Common applications include:
- Facial moisturisers
- Body lotions
- Nourishing creams
- Facial oil blends
- Skin-conditioning products
- Specialty cosmetic formulations
The final product should be evaluated for skin compatibility and stability.
2. Facial Oils and Serums
Cosmetic formulators may incorporate Hazelnut Oil into facial oil blends and selected oil-based serums. Its smooth texture can help create formulations designed for comfortable application.
It may be blended with other suitable carrier oils according to the desired texture, stability and product requirements.
3. Massage Oils
Hazelnut Oil can be used as an ingredient in massage oils and body oil blends. Its spreadability and emollient properties make it useful in selected massage formulations.
The oil should be evaluated for oxidation stability, odour and compatibility with other ingredients before commercial use.
4. Hair Care Products
Suitable cosmetic grades of Hazelnut Oil may be incorporated into hair oils, conditioners, hair masks and other hair-conditioning products. It can contribute to the oil phase of a formulation and influence the feel and manageability of hair.
5. Soap and Personal Care Products
Hazelnut Oil may be used in soapmaking and other personal care products. In soap formulations, its fatty acid profile affects the characteristics of the finished soap.
Formulators should test the recipe for hardness, lather, stability and other desired properties before production.
6. Food Industry
Food-grade Hazelnut Oil is used in selected culinary applications, salad dressings and specialty food products. It may have a characteristic nutty aroma and flavour, particularly when produced from roasted hazelnuts.
Its suitability for cooking depends on the specific product, processing method and intended use. The manufacturer’s guidance should be followed.
Important: Hazelnuts are tree nuts and can cause allergic reactions. Food manufacturers should account for applicable allergen labelling and handling requirements.
7. Cosmetic Manufacturing
Hazelnut Oil is a plant-derived emollient that can be used in creams, lotions, body oils and other cosmetic formulations. Manufacturers should select a grade that meets the relevant cosmetic specifications.
8. Specialty Oil Blends
Hazelnut Oil may be combined with other fixed oils, such as almond oil, avocado oil, jojoba oil or grapeseed oil, to develop blends with specific sensory and formulation characteristics.
Compatibility and stability testing are recommended before a blend is introduced into a finished product.
Key Characteristics of Hazelnut Oil
Rich in Oleic Acid
Hazelnut Oil commonly contains a high proportion of oleic acid, a monounsaturated fatty acid. Linoleic acid and other fatty acids are also present. Exact proportions vary according to variety, growing conditions and processing.
Emollient Properties
The oil is used in cosmetics because it can help soften and condition the skin. Its performance depends on the complete formulation rather than the oil alone.
Smooth Texture
Many Hazelnut Oil grades have a smooth texture that makes them suitable for selected facial oils, massage products and personal care formulations.
Naturally Occurring Minor Components
Depending on processing, Hazelnut Oil may contain naturally occurring minor components, including tocopherols. Their levels can vary and should not be assumed without product-specific analysis.
Oxidation Stability
Although its fatty acid profile contains a substantial proportion of monounsaturated fat, Hazelnut Oil can still deteriorate through oxidation. Appropriate packaging and storage help maintain quality.
Important Quality Parameters
Businesses purchasing Hazelnut Oil should review the supplier’s technical documentation and confirm that the product is suitable for the intended application.
Important checks may include:
- Botanical identity and kernel source
- Extraction and refining method
- Fatty acid profile
- Acid value and peroxide value
- Colour, odour and appearance
- Moisture and impurities
- Relevant contaminant testing
- Allergen information for food applications
- Certificate of Analysis (COA)
- Technical Data Sheet (TDS)
- Safety Data Sheet (SDS), where applicable
Food-grade and cosmetic-grade products may have different specifications. Confirm the grade and intended use with the manufacturer before purchasing.
How to Store Hazelnut Oil
Correct storage helps preserve the oil’s quality.
- Store in a tightly sealed, suitable container.
- Protect the oil from direct sunlight.
- Avoid excessive heat.
- Minimise exposure to oxygen after opening.
- Follow the supplier’s recommended storage temperature.
- Observe the stated shelf life and handling instructions.
Food-grade oil may require additional precautions after opening. Always follow the product label and manufacturer’s recommendations.
Safety and Precautions
Hazelnut Oil requires particular care because hazelnuts are a recognised tree-nut allergen. People with hazelnut allergies should not assume that an oil is safe simply because it has been processed or refined. Anyone with a known allergy should seek advice from a qualified healthcare professional and follow product-specific allergen information.
For cosmetic applications, manufacturers should assess skin compatibility and follow applicable cosmetic regulations. Discontinue use if irritation or an adverse reaction occurs.
Only products specifically manufactured and tested for food use should be used in edible applications. Cosmetic or industrial grades should not be consumed.
