Molecular fragrances are fascinating. Often referred to as ‘your skin but better’ fragrances, they offer people a whole new way to experience scent.

Rather than using more traditional ingredients like natural extracts or essential oils, they are created entirely from synthetic materials.

In almost all cases, molecular fragrances are known for being minimalist and unique, thanks to the way they interact with your skin.

While there is a lot to be said for beautiful and complex fragrances, the minimalist dance on the skin, offering an intimate representation of how you smell naturally – just with a little enhancement.

Without using natural ingredients, molecular fragrances mimic notes like amber, musk and woody scents. They often play with how we perceive smell, often becoming unnoticeable to the wearer, but noticeable to others and at the same time blending with our skins natural chemistry to create a truly personal fragrance.

It sounds a little like magic.

Another thing that you may notice with molecular fragrances is that they rarely have a typical pyramid structure. Instead, they can feel more like they shift over time, sometimes perceptible and other times not.

What are the aroma molecules in molecular fragrances?

Starting with what might be the most well-known one:

Iso E Super

Known for its musky, woody and some consider a velvety note. Renowned for its ability to disappear, because some people can smell it, and others can’t - at all. One of the fragrances that is most well-known for using just this ingredient is Escentic Molecules .

But it was the use of it in that shot it into the stratosphere of popularity.

Ambroxan

Ambroxan is typically used as a replacement for – a substance that is banned in many countries due to animal welfare reasons. Ambergris is a solid grey waxy material that is found from the digestive system of a sperm whale. Amroxan offers a similar ambery-woody note, with a slight nod to the animalistic qualities of ambergris.

Typically, ambroxan helps bring some comfort and warmth to a fragrance, while enhancing its longevity too.

Much like Iso E Super, ambroxan has its quirks. It can cause temporary inability to smell it, called temporary anosmia. One of the most interesting cases of this is people who wear BR540 often. Overexposure to it, can result in being unable to smell it.

Ambroxan can be found in Escentric Molecules , and Juliette Has a Gun, .

Galaxolide

First synthesised in the 1960s by Firmenich, it is now one of the most popular synthetic musks.

While Abroxan is ambery and woody, Galaxolide is sweet, clean and slightly floral – an if you know your molecules, you’ll know this one if often added into fabric softeners and detergents to increase the fresh, clean scent and increase the longevity.

For a true experience of Galaxolide, try out by Monoscent. It is good to note that this one has been reported as a threat to aquatic life since it is not biodegradable.

Cashmeran

Cashmeran is a trademark ingredient from IFF (International Flavours and Fragrances). The name implies much of what you can expect from it. Incredibly versatile it smells slightly spicy, a little bit musky and even powdery.

One of the benefits of using Cashmeran in a fragrance is that it expands and elevates floral notes, when used. You can smell Cashmeran as a standalone in .

What are the characteristics of a molecular fragrance?

Like we said in the opening, molecular fragrances are fascinating. They have a unique ability to interact with your body chemistry, your skin and the environment around you. Making them one of the most personal fragrance types around.

They also work their magic when used in conjunction with other scents.

Rather than evolve in a predictable way, they change based on your skin's temperature, warmer skin can enrich some molecules, making them deeper and woodier. Both your skin oil levels, and pH levels will have an impact on the molecules, sometimes making them more noticeable, other times making them almost disappear.

And the risk factor comes in a little with the fact that molecules like Iso E Super can be completely undetectable to some noses.

Escentric Molecules Molecule 01, Iso E Super is a beautiful example of how versatile these types of fragrances can be. For one person they may smell warm and woody, while for others there might be a barely perceptible waft of ‘clean’. For others it won’t smell of anything at all.

Is there a point to a fragrance that might disappear?

The beauty is in the subtly of them. You might not notice the scent after a while, but others might. Depending on your day, you might find that it changes its profile. And it is that unpredictability that make them fun.

When worn alone they will sit close to the skin, and bloom and project or disappear at will.

The layering potential for molecular scents is incredible too. Using the profiles and understand which work best with florals, and which work best with woody scent. Using a few spritzes of Iso E Super or Ambroxan to boost longevity, or Galaxolide to amplify notes it takes layering to a unique new level.

Can’t wait to experiment? Here is a list of ten molecular fragrances to get you started:

Escentric Molecules, , the Iso E Super powerhouse.

Juliette Has a Gun, , Cetalox and Ambrox, hypoallergenic and ultra-skin-like.

Esentic Molecules, , Ambroxan super hit, adds warmth without it being heavy.

Nomenclature, , using Helvetolide to offer a fresh musk with an almost pear-like twist.

Zarkoperfume,, a proprietary synthetic molecule that ‘shifts over time’ and changes based on body temperature.

D.S & Durga, , Iso E Super, Ambrox and Vetiver Acetate, designed to be layers, works well as a minimalist fragrance.
