Geosmin Neat
$25.00 – $900.00
CAS#: 23333-91-7
The odor of Geosmin is best described as the smell of the air after rain falls on dry soil. Both geosmin and another earthy-smelling compound, 2-methylisoborneol (MIB), are produced by soil microbes such as cyanobacteria and actinomycetes. Geosmin has also been identified in the scent produced by the flowers of some species of cactus, perhaps as a clever enticement to pollinators that expect that water might be present.
Humans can smell concentrations as low as 10 parts per trillion of Geosmin in water. The characteristic odor of soil was first investigated by Berthelot in 1891. In 1965 the structure of the responsible compound geosmin was determined by Gerber. It was not until 1981 that the pathways for the biosynthesis of these compounds were determined.

This is one of the most interesting aroma chemicals out there, and everyone should have it. It’s a bit hard to rate this, as it would be like rating rain or dirt on a scale of one to five. Geosmin is what you smell in the air when it rains; that is, it rises from the ground. In trace amounts, that’s what it smells like. When you smell it straight out of the bottle, it smells like dirt. It also smells like beets, and I often taste it in salads.

Geosmin is everything that I imagined it would be…wonderful. I also feel that everyone should have some.

Geosmin is an exceptional material. Many aroma chemicals give you a very abstract blurred image – is it fruit or seed or tree? Anything is possible, just use your imagination. In case of geosmin you’ve got an exact image of wet soil with outstanding naturalness and you can hardly correlate geosmin with something else. Intensively popularized by Brosius (Demeter, CB I Hate Perfume) this one can be used in the high variety in genres when you need the natural effect of soil, forest rain, river water, melting ice and things like this.
This substance is extremely intensive and very easy to overdose. You may think that even the pure material smells not so offensive, but I highly recommend to dilute it to 0,1% or even to 0,01%. Higher quantities can give you an effect of Peppa pig’s muddy puddles, moldy vault, sepulchral dampness and other side effects, otherwise you need a gothic gloomy perfume. So despite this stuff is very costly, its profitable because you need just tiny traces of it.

wonderful very powerful, even in the bottle you can smell this from meters away. damp earth

I’ve always bragged that I can smell when it is about to rain. Then someone told me that it is the rain on soil that I am smelling. I’ve always loved that smell and geosmin is exactly that. Just a whiff will send me “forest bathing,” wherever I happen to be. What a find!

Outstanding, powerful material! I have Geosmin at 1% and while I find even at that strength it’s tenacious and wonderfully soil like, and I’ve used it on its own for an educational resource (by it self it is the star of the show), but at a lower % it can easily get buried in a more agrestic or heavy oakmoss-leaning blend so if you want both, a higher dose (that you’ll get from this) offers a very powerful earthy quality without the heaviness of some other classic ‘earthy’ materials. I agree with Mat that a higher concentration does alter the odour character dramatically (Mat’s muddy puddle nails it!) so be careful. This is a great material for non-standard scent projects such as entertainment/theme park interactions/novel ‘sensory’ display experiences. The higher concentration seems suited to low-throw scent delivery models (but still, be careful with this one).
