Ethyl Linalool, also known by the chemical name 3,7-dimethyl-1,6-nonadien-3-ol, is a notable achievement in synthetic perfumery because it does not occur naturally at all. Appearing as a clear, colorless liquid, this material diffuses a fresh floral character blended with a bergamot-like citrus nuance, yet it feels softer and noticeably less sharp-edged than natural linalool. Ethyl Linalool was developed from the desire to overcome linalool’s drawback of evaporating too quickly, leading chemists to modify its structure by adding carbon atoms to increase molecular weight and improve stability. The result is essentially a “slow-evaporating linalool” that plays an important role in supporting floral notes, brightening the top, and extending a lively freshness well into the heart of a composition.
Description
Ethyl Linalool is a captivating odor profile that sits across fresh floral, citrus, and gentle woody facets. It functions from the top through the heart, acting as a modulator and booster for floral notes, helping them feel more harmonious. Its scent is very close to linalool-suggesting rosewood-like tonality, lavender, and bergamot-yet it is gentler and warmer, with reduced woodiness and spiciness. With a fuller body and a subtle smooth, waxy feel, it has a distinctive appeal.
Odor intensity is moderate, but its substantivity is clearly superior to linalool, lasting for hours rather than flashing off quickly. This makes it a smooth “bridge” between the top and heart. It is commonly used to build attractive accords such as rose, lavender, bergamot, or muguet (lily-of-the-valley), enriching the overall profile, rounding off harsh edges, and delivering a more natural, persistent freshness. A popular pairing is with linalool: linalool provides an immediate, vivid lift at the start, while Ethyl Linalool maintains continuous freshness and creates an appealing extended effect. It also blends very well with Coranol or linalyl acetate. Ethyl Linalool is typically used neat at 100% as a convenient liquid, and it dissolves well in alcohol and in oils.
Applications
Ethyl Linalool is widely used in perfumery, especially shining in modern bright florals and fresh fougères, where it brings vibrancy to alluring scents. Beyond fine fragrance, it is also a common choice in cosmetics and personal care products such as shampoos, shower gels, and body creams, thanks to its pleasant odor and a lower irritation tendency compared with some natural essential oils. In soap, Ethyl Linalool stands out for better stability than linalool under alkaline conditions, helping maintain quality over time. As a usage recommendation, IFRA standards do not impose a specific concentration limit provided purity requirements are met; however, peroxide levels should be kept as low as possible and below 20 mmol/L for optimal safety.
From an allergy perspective, Ethyl Linalool is regarded as safer and less irritating than natural linalool. However, like other terpene-derived materials, if stored poorly and exposed to air it can oxidize, potentially forming skin-sensitizing oxidation products. For effective storage, keep it in tightly sealed containers away from light and heat, and consider adding antioxidants such as BHT or tocopherol to maintain quality.
A true “workhorse” in perfumery, Ethyl Linalool appears in thousands of modern fragrance formulas, serving as a foundational component in perfumes with tea, jasmine, and “marine” impressions-such as CK One by Calvin Klein or J’adore by Dior-often as an important part of the floral complex. According to Perfume and Flavor Chemicals Volume 1 and 2 by Steffen Arctander (Monograph No. 1238), Ethyl Linalool has a floral, oily-woody, soft odor with medium retention; its notes are not as “fresh” as linalool’s, but are smoother, waxier, and less volatile. It is used in perfumery as a modifier for linalool, and also as a fixative and blender/modifier in muguet, lilac, lily, tea, and many other fragrance types.
