The beauty of working for a fine perfumer like Penhaligon’s is that my eyes have been opened to the weird and wonderful world of fragrance creation and the amazing ingredients that are used to make perfume, many of which most people have no idea about! So, I have decided to share the origins of the five ingredients which are, in my view, the most astonishing.
Aldehydes
When I first learnt that Aldehydes were a key ingredient in our Elisabethan Rose fragrance I assumed it was a flower – it certainly didn’t occur to me that it might be a synthetic note, produced through the refraction of oil! Although perfumers have been using Aldehydes for over a century, it wasn’t until 1921 when Ernest Beaux created the infamous Chanel No 5 that this ingredient became widely known, and it is now used extensively across the industry on account of the sparkling effect it adds to a scent.
Frankincense
Any mention of gold, frankincense and myrhh will probably make most of us think about wearing a tea-towel on our heads in a nativity play. At that age we probably didn’t appreciate that frankincense was worth more in its weight than gold and was the cornerstone of a major commercial empire. Inscriptions dating to 1500BC in the Deir el Bahri temple in modern day Luxor, describe how Queen Hatsheput personally ordered expeditions to find ‘sweet smelling resin and frankincense’ for the gardens outside the temple. Although frankincense is not as valuable as it once was, it has had a diverse range of uses throughout the years varying from medicine, incense, kohl and of course perfume!
Hyraceum (Africa Stone)
One of our two new Anthology Collection launches later this year (Esprit Du Roi) contains Hyraceum, also known as ‘Africa Stone.’ Hyraceum is the fossilised urine of the Cape Hyrax or Dassie – certainly not an ingredient you would expect to find in a perfume! These animals live in Southern Africa and resemble large guinea pigs! Hyraceum is harvested without disturbing the animals (simply by digging it up!) and produces a complex animalistic scent similar to a heady mix of Musk, Civet, Castoreum and Tobacco. It is a wonderful alternative to synthetic musks and we thank the Dassies for their hard work creating it!
Heliotrope
Heliotrope is the floral gourmand note which adds to the sweetness of our Cornubia fragrance. A purple flower native to Peru, a heliotrope will turn and follow the sun during the course of the day, hence the derivation of its name from the Greek words ‘helios’ and ‘tropos,’ which mean ‘sun’ and ‘turn’ respectively . The Roman poet Ovid attributes the origins of the heliotrope to the story of the nymph Clytie, who was turned into the flower by the gods on account of her unrequited love for the sun god Helios: moved by pity for the girl as she pined fruitlessly for Helios, the gods transformed her into a ‘bloodless plant,’ destined to gaze forever at her love.
Ambergris (Grey Amber)
Ambergris is a highly prized ingredient though it is rarely used in its natural form in modern perfumery. Often mistaken for the fossilised tree resin Amber, Ambergris is formed in the intestine of the sperm whale and although it is not exactly known why this secretion occurs, it is thought to facilitate the digestion of sharp objects such as squid. The secretion can be found floating in the sea or washed up on beaches and, although it does not sound like a particularly appealing substance, once collected it is a valuable commodity. It is primarily used as a fixative in the base of fragrances but imparts a beautifully soft, earthy and slightly antiseptic scent.
So there you have it, the five most unusual ingredients I think exist within perfumery. What are your favourite ingredients and why?








This was a marvellous find. I googled for an image of the flower heliotrope and I found your article. I was looking for a picture of this flower because- my mother often uses the word describing a colour. Then I found out it is a flower (the name of the color ‘heliotrope’ being named after the flower). I just LOVED the word. “Heliotrope’. So bizarre -and deliciously strange a name for a colour. And I found your article. I love the fossilised animal urine- how could you go past that for old-world and mysterious!!(One might expect to find it in a dingy old apothecary’s shop ). AND- Im so pleased that none of these wonderful things is got via doing a creepy cruel thing too any creature. Theres so much of this about-a nd it sucks the beauty out of any created thing for me. I want to find my own piece of Ambergris- and smell it, and keep it!! That word too!! -Ambergris-so lovely, I think of pirates and queens and an old gone world as well. Thrilling-all of it.
Hi Susan, we’re delighted to hear you enjoyed our post on weird ingredients in perfumery. It really is fascinating isn’t it!
I’m curios if you have any suggestions on where to purchase wholesale Hyraceum?
Hi JK, I’ve contacted our Head of Fragrance to find out. As soon as I have an update (should be mid week) I’ll let you know here.
Are you making your own fragrance?

My next visit to the lab will have a purpose – get acquainted to hyraceum!
Let us know how you get on!
Do I have to choose?
I’d say out of those five I’d be most fascinated by Ambergris. I haven’t smelled any of these in their natural state either, except Frankincense. Ambergris sounds like the thing of legend, sea-gold and it rewards its finder with a handsome sum! Heston Blumenthal used in chocolate milkshake and edible perfume – it must taste as good as it smells…
Wow you do learn something new everyday! I never knew that about Heston Blumenthal – how interesting.
I really recommend trying to smell all of these ingredients in their natural state, they’re not at all what you expect. Ambergris is a definite must! A musky yet a subtle and pleasant aroma. Very unusual!
Oh yes do give it a look up on 4OD. The episode might still be kicking about somewhere. And definitely, I’ve I’m ever lucky to come by a lump of Ambergris, I’ll be straight in there.
Actually I was lucky enough to smell a vintage Ahmed Soliman perfume, complete with real grainy musk granules. Never before had I experienced a smell as rich and deep in my life. Beautiful.
I’ll definitely keep an eye out for it and let you know if I find it! Sounds incredibly interesting. Thanks!
