I love the in depth way you explain things. Huge perfumery career ahead of you.

Great video Sam. You made me reexamine bicyclononalactone as I thought I hated it. To me it was like C18 without the coconut - the waxy dry part. I've just compared the two and I think you are right about it being between coumarin and C18. I now see the dry herbaceous woody aspect. I think originally I was unhappy with it as I had been aiming for coconut.

Look forward to seeing your coumarin formulas. I recently used it to produce a powdery woody male talc-like accord with ethyl vanillin, sandalore, timbersilk, lyral and ethylene brassylate.

Am learning a lot from your videos. thanks for this information.

Sam! Please make a vid onto liquor notes! I'm assuming you're gonna talk about mellis, honey essence, gamma undecalactone and certain aldehydes. It's an extremely interesting category! Best regards from Mexico

Comprehensive video, loved the structure and topics covered, thanks for sharing! Coumarin usually comes in powder form, do you know why this is and how long can it be 'kept' once diluted with perfumers alcohol?

Greetings Sam, I absolutely love your videos and your passion to share your knowledge. You make the world a better place! Watching the video I got inspired to investigate the chemical compound of different citruses by first downloading chemical analysis of different citrus EO's and then buying those AC's available. Start blending, building, and by that learning more about citrusses. Taking into account that the ratio of AC in EO's vary from different region in addition from year to year I think this might be an interesting project to pursue.

Desde Argentina te leo(con el traductor 😂😂) Fabulodas tus explicaciones

Thank you so much for pointing out which of the IFRA categories to go by. I like to use coumarin in my blends but I never understood which of the IFRA categories to go by so I would always go with the most stringent just to be safe. It seems that I could've used a lot more.

Hello Sam, thank you for all your videos always touch on interesting and useful topics.
most formulas have many components and it is not possible to have them all at hand, I wonder if you will have some list of substitutes because I have not been able to get information about it.
thank you in advance for your help.

I'm a Coumarin junkie! I love Alexandria II, which is full of it. Bycyclo is not my cup of tea, still looking for a good way to use it.

Sam what quantity of maltol shud be used in one kilogram of dpg

[tessselllate]

Funnily enough the specific fern you showed actually does have a scent! It's a hay fern and smells kind of like hay if you crush it up in your hand.

You don't have any obligation to follow IFRAs ridiculous limits. I refuse to let IFRA destroy classical perfumery and I'd have hoped you did too.

[annelorelaisison]

I heard and read that coumarin in perfume is toxic to the liver. Is it true?

[meghayadav]

I am big fan of perfume and big fan of you 😊💫

[Africanre]

I think I’m in love . Do you sell courses ?

Not sure how the IFRA site is supposed to work but on my mobile it doesn't seem to. If you do get any hits on a search term the site will say so but doesn't display them. What am I doing wrong?

[oenkayee]

Hey may i know is that tonka bean makes allergic to several people?

[thiagoribeiropereira]

To avoid problems and work more easily I always use coumarin diluted to 1%.

Hi Sam? Could you give me formula for reed diffuser?
