Hydrogenated Hazelnut Oil
What Is It?
Corylus Americana (Hazel) Seed Oil and Corylus Avellana (Hazel) Seed Oil, also called hazelnut oil, are oils obtained from edible hazelnuts. The addition of hydrogen to hazelnut oil results in Hydrogenated Hazelnut Oil. Hazelnut oil may be used in bath products, eye makeup and skin and hair care products.
Why Is It Used?
When used in cosmetics and personal care products, hazelnut oil and Hydrogenated Hazelnut Oil function as skin-conditioning agents – emollient and skin-conditioning agents – occlusive.
The tree Corylus Americana is native to North America, while Corylus avellana is native to Europe. The seeds (or nuts) of both species may be eaten as food. Hazelnuts also called filberts. Hazelnut oil contains 66-85% oleic acid, 7-25% linoleic acid, 4-9% palmitic acid and 1-6% stearic acid.
The safety of Corylus Americana (Hazel) Seed Oil, Corylus Avellana (Hazel) Seed Oil and Hydrogenated Hazelnut Oil has been assessed by the The Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in dermatology, toxicology, pharmacolgy and veterinary medicine. The CIR includes participation by the U.S. Food & Drug Administration and the Consumer Federation of America. (CIR) Expert Panel. The CIR Expert Panel evaluated scientific data and concluded that these ingredients were safe for use in cosmetics and personal care products. Botanical and botanically derived ingredients used in the formulation of cosmetics are generally mild and safe.
Prior to marketing the finished cosmetic product, the safety of each ingredient must be substantiated in accordance with 21 CFR 740.10. Safety substantiation of cosmetic ingredients may include tests for ocular and skin irritation as well as allergenicity, phototoxicity, photoallergenicity and mutagenicity, depending on the application or intended use. There is a considerable body of information about the safety of botanical ingredients and a well-established history of use. These resources are consulted to ensure the safety of these materials as they are used in cosmetics.
CIR Safety Review:
Corylus Americana (Hazel) Seed Oil, Corylus Avellana (Hazel) Seed Oil and Hydrogenated Hazelnut Oil were included in the CIR Expert Panel’s review of plant-derived fatty acids oils. Based on a history of safe use in food, the composition of the oils, and data indicating these ingredients were not dermal irritants or sensitizers, the CIR Expert Panel concluded that plant-derived A natural organic compound that consists of a carboxyl group (oxygen, carbon and hydrogen) attached to a chain of carbon atoms with their associated hydrogen atoms. The chain of carbon atoms may be connected with single bonds, making a ‘saturated’ fat; or it may contain some double bonds, making an ‘unsaturated’ fat. The number of carbon and hydrogen atoms in the chain is what determines the qualities of that particular fatty acid. Animal and vegetable fats are made up of various combinations of fatty acids (in sets of three) connected to a glycerol molecule, making them triglycerides. oils including hazelnut oil and Hydrogenated Hazelnut Oil were safe as used in cosmetic products. Some people are allergic to tree nuts including hazelnuts. Therefore, the FDA Food Allergen Labeling and Consumer Protection Act requires that all food containing hazelnuts be clearly labeled.

More Scientific Information
In naming plants, botanists use a Latin name made up of the genus and species of the plant. For example, under this system the plant, the one species of hazelnut tree is known as Corylus americana Marshall where ” Marshall ” stands for the name of the person who first described the type of plant specimen. Plants are also known by a common name that has been handed down through generations. These common names may vary from country to country. Therefore, Latin names, which are more likely to be recognized in many countries, are frequently used on the label of a product to identify an ingredient made from plants.
