Hazelnut is a fragrance oil derived from the nuts of the hazel tree, commonly used in perfumery for its rich, nutty, and slightly sweet aroma. It is often employed in gourmand compositions, where it adds depth and warmth, complementing other sweet notes like vanilla and chocolate. Hazelnut can also be found in more complex blends, where it enhances the overall character of the fragrance, providing a creamy texture that can soften sharper notes. In terms of safety and regulatory considerations, hazelnut oil may be subject to allergen labeling requirements, as it can be a potential allergen for individuals with nut sensitivities. While specific IFRA restrictions may vary, it is advisable for formulators to be aware of the potential for allergic reactions and to use hazelnut oil judiciously in cosmetic formulations. — AI-generated summary, 2026-09-02.
