Much like there’s a world of fashion that seems to be divorced from the idea of looking good, there’s a section of the fragrance industry that focuses its efforts not on making you fragrant, but in crafting scents that emulate stuff most people would never want to smell like.

These tend to fall into a couple of camps: artistic concepts, often from rule-bending fashion and fragrance houses like Comme Des Garçons; and recreations of real-world scents you wouldn’t traditionally spritz on for date night, but are akin to perfumers flexing their noses by crafting the scent of a garage or baby powder – not things you can just extract the essence of and bottle.

So while none of the fragrances below will likely slot into your everyday scent rotation, they are impressive. In the same very niche way that watching someone recite pi to hundreds of decimal places is impressive.

Etat Libre d’Orange Sécrétions Magnifiques

French perfumer Etat Libre has a thing for avant-garde scents. Launched by a luxury perfumer bored of working at commercial brands who played it safe, its 30-fragrance stable features such gems as Fat Electrician – a scent inspired by the hazardous life of a young gigolo in 1970’s New York (really) – and Tom of Finland, an ode to the master of homoerotic illustration that features top notes of poppers.

But its most, er, divisive scent is probably Sécrétions Magnifiques, created by nose Antoine Lie. Spray on and you’re hit by a waft of blood, sweat, semen and saliva. It’s a coital quartet for when you want to bring the bedroom to the boardroom.

Blood Concept Red+MA

Antoine Lie’s friends might think he’s slightly obsessed with bodily effluvia, since he also created this emission-inspired scent for Blood Concept.

The niche fragrance house produces scents inspired by blood and named for blood types, and this juice is designed to emulate the first bodily fluids we experience when we enter the world; blood and milk. Which translates to super-metallic notes mixed with a milk accord for something that could probably clear most rooms.
