Safety Information

The safety of Corylus Americana (Hazel) Seed Oil, Corylus Avellana (Hazel) Seed Oil and Hydrogenated Hazelnut Oil has been assessed by the Cosmetic Ingredient Review (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.

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.
