Fatty, viscous, low-volatility warmth. Less sharp than aldehydes, less sweet than wax. The specific slickness of a liquid that coats surfaces. Denser than creamy, less structured than waxy.

The Full Story
Oily notes describe a specific textural quality: the fatty, slightly viscous, low-volatility character of lipid-rich materials. This can reference natural vegetal oils, mechanical oils, or the oily qualities of certa in arom a chemicals.
Many raw materials have inherent oily qualities. Orris butter has a distinctly fatty quality. Costus root oil smells of rancid animal fat. Gamm a-decalactone has an oily-creamy quality at higher concentrations.
Oily notes function as textural modifiers in the heart-to-base zone. They add weight, viscosity, and lubricant-like smoothness.
The human nose can distinguish olive oil from canola oil by smell alone, even though both are nearly pure triglycerides. The difference comes from trace volatiles: hexanal and cis-3-hexenol in olive oil produce its green-fruity character.
Extraction & Chemistry
Extraction method: Not a single extractable material. The oily quality comes from various sources: cold-pressed natural oils or the fatty qualities of specific synthetic molecules.

In Perfumery
Textural heart-to-base modifier adding weight and viscous smoothness. Sources include orris butter, costus root, gamma-decalactone at high doses. Must be carefully dosed to avoid rancidity. Adds body to thin compositions.
