Petroleum

Note Profile

Abstract

About

Petroleum is a concept note, not an extract. No fine-fragrance house distils crude oil, so what perfumery calls petroleum is an accord built to stand for it. The one trade description found leads with two words that fight each other: sweet and industrial. The sweetness is the chemical kind, an alkane sweetness with no sugar behind it, so it sits on sweet_vanillic only because this vocabulary has nowhere else to put a sweet claim. The core of the note is mineral, the oily-metallic reading rather than the chalky one. Everything here rests on one trade page and one chemistry article, which is why the confidence is 0.30 and the spreads are wide.

Scent Profile

Mineral leads and is the oily-metallic kind, the same reading as motor-oil rather than the chalky wet-stone kind. Sweet_vanillic is the note's other half and is the hardest number in this file: both sources lead on the word sweet, but neither means dessert, so read it as the sweetness of a clean alkane and not as vanilla. Smoky carries the acrid edge, which has no facet of its own in this vocabulary. Dry_woody is Fragrantica's own subcategory word and is the only support it has. Sulphurous is the sour-crude end of the material, where hydrogen sulphide turns the same oil rotten. Amber_resinous and a small leather sit underneath as the tarry, rubbery company the note keeps, and both are borrowed from the cluster rather than stated of petroleum itself.

Origin

Crude oil and its lighter fractions. Premiere Peau's glossary states plainly that petroleum 'functions as a concept or fantasy note in modern fragrance compositions. Not derived from a single natural extraction; the impression is built from multiple materials.' The smell it describes comes from 'a complex mixture of alkanes, cycloalkanes, and aromatic compounds that the nose perceives as simultaneously sweet and industrial'. Wikipedia's article on sweet crude oil supplies the only chemical anchor for the sweet/sour split: 'The term sweet originates from the fact that a low level of sulfur provides the oil with a relatively sweet taste and pleasant smell, compared to sulfurous oil.' High-sulphur crude carries hydrogen sulphide and reads rotten instead. That single variable moves the note further than any other, and no source says which end of it perfumery is imitating.

Usage in Perfumery

Premiere Peau places it in 'conceptual and anti-perfume compositions alongside gasoline, rubber, and asphalt to explore industrial olfaction'. Fragrantica files it under 'Natural and synthetic, popular and weird' with the subcategory 'woody, rich, metallic'. Attestation is thin and one-sided: 5 Fragrantica placements and none on Parfumo. Treat it as a signature effect for a whole composition rather than a material a perfumer doses against others.
