Fragrance: definition and use in perfumery

Definition

A fragrance is a perceptible scented composition, used in perfumery to describe both the finished product applied to the skin and the raw aromatic concentrate created by the perfumer. In everyday language, fragrance and parfum are often synonymous. In professional vocabulary, fragrance more precisely denotes the scented concentrate, since the word parfum also refers to a specific type of finished product — the extrait de parfum.

In professional vocabulary, this word is often preferred to "parfum" to describe the scented concentrate, since the latter term also covers a particular type of finished product — the Extrait de Parfum — with a high concentration level. Fragrance, on the other hand, does not presuppose any specific concentration and can be found equally in an eau de toilette, a shower gel, a candle or a household product.

Etymology and origin

The English word fragrance, widely adopted into French within the cosmetics and fragranced-products sector, comes from the Latin fragrantia, derived from the verb fragrare, meaning "to give off a pleasant scent". This Latin root also gave rise to the French word "fragrant", a literary adjective describing something that gives off a sweet parfum. The use of the term fragrance in French developed alongside the internationalisation of the fragrance industry, notably under the influence of European regulatory nomenclature and the standards of the IFRA (International Fragrance Association), the body that governs the use of odour molecules worldwide.

Historically, the earliest fragrances were exclusively of natural origin — resins, woods, flowers, spices — and served ritual or medicinal purposes long before becoming personal adornments. The notion of fragrance as we understand it today truly took shape with the rise of organic chemistry in the 19th century, which enabled the synthesis of odour molecules and considerably broadened the perfumer's palette.

In practice

In the process of creating a parfum, fragrance refers to the scented concentrate developed by the perfumer — also called a "nose" — from a blend of natural and synthetic raw materials. This concentrate is then diluted in a solvent, usually ethyl alcohol, at varying proportions depending on the desired type of finished product. The higher the fragrance level in the final formula, the more intense and long-lasting the parfum will be on the skin.

On the labels of cosmetic products sold in Europe, the term fragrance — or its Latin equivalent parfum — appears in the INCI (International Nomenclature of Cosmetic Ingredients) list to indicate the presence of a scented blend whose exact composition is protected as a trade secret. This single entry may nevertheless bring together several hundred distinct molecules, which can make label reading complicated for consumers who are sensitive or allergic to certain components.

Examples

A floral fragrance will typically be built on materials such as rose absolute, neroli or orange blossom, to which synthetic molecules are added to enhance their naturalness or longevity. A woody fragrance, meanwhile, will draw on ingredients such as Virginia cedar, sandalwood or molecules like Iso E Super, widely used for its velvety texture and woody-amber resonance. These examples show that fragrance is never a single isolated note, but always an olfactory architecture conceived as a whole.

In the personal care or household products sector, fragrance also serves a functional and marketing purpose: it masks the scent of chemical formulas while creating a distinctive sensory signature for the brand. A laundry detergent may thus contain a fragrance specially designed to withstand rinsing and linger on fabrics, with technical constraints very different from those of a luxury parfum.

Key takeaways

Fragrance is the generic term used to describe any scented composition, whether a raw concentrate used in formulation or a finished product intended for the skin. Its scope extends well beyond fine perfumery to encompass all industries that incorporate odour molecules into their formulas. Understanding this distinction helps in reading labels, technical descriptions and the vocabulary used by industry professionals.

Bearing in mind that fragrance and parfum are not always synonymous is essential for navigating the olfactory world with precision. The former refers to the material or composition in its overall functional sense, the latter to a finished product with its own codes of concentration and use. This nuance, though subtle, underpins the entire professional language of perfumery.
