A vocabulary for aromatic materials
Essential oil, absolute and extract describe ways of obtaining or preparing aromatic material. They are useful words to know when a perfume house discusses its palette. ISO 9235 is a vocabulary standard for aromatic natural raw materials. Its existence also makes a useful point: “natural” does not mean that nothing has been processed.
A material's source and its preparation are separate parts of its identity. To understand a particular perfume, a name such as rose or citrus is only the beginning of the inquiry.
Distillation and extraction
In steam distillation, aromatic plant material is exposed to steam and the resulting vapor is cooled. The recovered aromatic oil and water can then separate. Solvent extraction provides another route: it can produce a concrete, from which an absolute is prepared through further processing. Fragonard's manufacturing guide describes these techniques and the older practice of enfleurage, in which fat captures the scent of flowers.
These are examples from perfumery in general. They explain the vocabulary of materials rather than prescribe one extraction method for every ingredient or disclose an Oilboros formula.
From material to composition
A perfumer works with relationships. A material that feels sharp alone may bring clarity to a softer composition. Another may give a bright passage enough weight to stay interesting. Describing those effects is often more useful than imagining each listed note as a separate layer.
Oilboros uses natural aromatic materials and makes perfume by hand in small, limited batches. The work of the house is expressed in the house story: recognizing a material's character and finding where to guide and where to yield.
Reading the language on a perfume page
A scent note describes what a perfume brings to mind. “Powdery” describes an impression, not a declaration that powder was added. “Gourmand” suggests an edible quality, without identifying a food ingredient. “Earth” can describe a character rather than a literal ingredient.
That is why a note list and an ingredient list serve different purposes. For Dill, the heart is dill, accompanied by citrus and earth in the scent description. For Oilboros No. 18, palo santo is the heart, with gourmand, powder and citrus facets. Those descriptions help you choose what to sample; they are not full formulas.
Let the material meet your own experience
You do not need to identify every material to understand a perfume. Begin with the impression it gives you: fresh or warm, soft or vivid, familiar or difficult to place. Then return to the description and notice whether it has helped you recognize something.
Try one composition at a time and give it room to develop. The aim is to find a perfume you enjoy living with, rather than pass a test of ingredient recognition.
