Cashmeran

What it is

A single synthetic molecule, trademarked and introduced in the 1970s, describing a material rather than any plant.

What it smells like

Warm and musky with a powdery, slightly woody feel, closer to a texture than to a smell. It is used to make a base feel soft and enveloping, and it is in a great many modern fragrances without ever being the note you notice.

Where it sits

Which layer of the pyramid it is listed in, across every fragrance here that carries it. A base note is one you smell for hours; a top note is usually gone within the first.

What it turns up with

How much more often than the catalogue average. 1.0x would be chance, so these are the things that genuinely travel with it rather than the things that are simply common.

When it is worn

Against the average fragrance here. The line marks that average, so a bar past it means this is worn in that season or setting more than most.
