Demystifying the Duo: Hazel Seed Oil vs. Hazelnut Oil
For anyone navigating the world of natural ingredients, the variety of names for a single product can be confusing. When it comes to the oil derived from the fruit of the hazel tree, the terms “hazel seed oil” and “hazelnut oil” are often used interchangeably. So, is hazel seed oil hazelnut oil? The definitive answer is yes. Both names refer to the same nourishing and versatile product extracted from the seeds of the hazel tree, Corylus avellana. This article will explore the botanical origins, shared properties, and diverse applications of this single, beneficial oil.
The Botanical Identity: Corylus avellana
The oil in question is obtained from the edible nut of the hazel tree, which is botanically known as Corylus avellana. This species is native to Europe and western Asia and is a member of the birch family. The “seed” in “hazel seed oil” is simply the nut itself. The process involves harvesting, cleaning, and drying the nuts before they are subjected to mechanical pressing, often through cold-pressing to preserve their nutrients. The resulting oil is a light, non-greasy liquid that ranges from light yellow to amber-yellow in color and carries a delicate, nutty aroma.
Why the Two Names?
The use of different names primarily comes down to marketing and context. In the cosmetics industry, the scientific or International Nomenclature of Cosmetic Ingredients (INCI) name is Corylus Avellana Seed Oil. Therefore, manufacturers may use "hazel seed oil" to reflect this formal designation. In culinary contexts and everyday language, the more common and familiar term "hazelnut oil" is typically used. Regardless of the name, the product and its beneficial properties remain identical.
