    Default ISO E Super as an Intensifier

    I was reading a few days ago about how ISO E Super is used as an intensifier in perfumery. I was made curious because I was trying to learn more about the frag I was wearing that day (a sample of Escentric 01). The following day, before going to work, I layered one spray of Escentric 01 with a couple of sprays of John Varvatos. By the end of the day, I couldn't get home fast enough to shower. I was extremely tired of smelling very strong JV all day. I don't think my co-workers were subjected to it (at least I hope not, and no one showed any reaction when I walked near them). While trying to shower off the fragrance, it just got stronger. I just had to let it wear off overnight.

    Today I again wore JV, this time without Escentric, and it behaved normally. For kicks, after work, I applied some Escentric to my arm, along with some M; Men. M; Men has very poor longevity on me, but when layered with the ISO E, it was a powerhouse, and didn't fade at all over several hours. As I am typing this, I am experiencing sickeningly powerful M; Men.

    I also get a peppery taste in my mouth when wearing frags containing this chemical.

    The moral of this story is to be careful when layering frags containing large amounts of ISO E Super (unless you want some unintended consequences). I suspect that TdH might show some of the same phenomenon. At the very least try your blend at home first.

    Of course, if you use it cleverly, perhaps you could increase the longevity of some of your perfumes that have problems with longevity. It seems to me that it is mainly the wearer whose nose is made more sensitive to certain aromachemicals, and not that there is substantially more sillage (but I may be wrong about this).

    I think you're on to something here. I have a big problem with Ormonde Jayne fragrances, all of them. Somehow they start out beautifully, then 10 minutes later, they amplify, and amplify, until I'm ready for skin grafts! (showers don't help, the stuff clings)
    I had the same problem with a sample of Lancome's Magnifique.
    All of these, I'm told, contain large amounts of Iso E Super in the base. Something about this molecule causes frags to go nuclear, at least to some people's noses. Terre d'Hermes contains it at a tolerable level, I don't mind that one. I think he used a lot in Kelley Caleche, which I can wear on occasion, but it's so strong!
    Perhaps it's good IFRA is trying to regulate Iso E Super....

    Ah, so perhaps I am not crazy ;-)

    I also have some problems with AdP Colonia Intensa, Rive Gauche, and the CdG incense frags. It wouldn't surprise me to hear they have large amounts of Iso E Super. I have not yet seen a problem with Terre d'Hermes.

    Totally agree JonB. Fragrances like TdH, Black Xs, Light Blue for women, Eau Fraiche by versace and the escentrics all smell similar and are powerhouses on me because of their large doses of Iso E Super. I wore Escentric 01 once and had to scrub it off cuz it was INSANE. It was too chemically, and although I only used a drop, it had the sillage of 4 sprays of Black Xs. So I think Iso e Super definitely is an intensifier - I have hunch though that it depends on your own skin chemistry.

    ps. I can taste it too!

    There's no doubt that the CdG incense series fragrances (and GdG 2 Man) contain Iso E Super®, as does Rive Gauche Pour Homme, as does AdP Colonia Intensa. Jean Claude Ellena, co-perfumer with Bertrand Duchaufour of AdP Colonia Intensa, uses Iso E Super® liberally in many of his creations, including Terre d'Hermès (in which it makes up 50%* of the formulation!!) and Poivre Samarkande (in which it makes up 70%* of the formulation!!!!) (*source: 1000fragrances.blogspot.com, "Rumors: End of Minimalism?" post). Other recent fragrances overdosed with Iso E Super® are Juicy Couture's Dirty English (2008) and Tauer Perfumes Incense Extrême (2008),

    Since it was first introduced in 1972, Iso E Super® has become a major aromatic chemical in many aesthetically and commercially successful fragrances. An instance of the former is Shiseido's legendary Féminité du Bois (Iso E Super® at 43%) created by Pierre Bourdon and Christopher Sheldrake and overseen by Serge Lutens. Iso E Super® can also be found in some other of Serge Lutens' fragrances under Lutens’ own name. It is one of only four aromachemical ingredients that make up 80% of the formula for Sophia Grosjman’s 1990 reworking of Lancôme’s original Trésor. Other women’s fragrances in which Iso E Super® features prominently are YSL’s Paris, Chanel’s Coco, Chopard’s Casmir, Calvin Klein’s Eternity, and Givenchy’s Amarige and, more recently, as noted above, Dolce & Gabbana’s Light Blue. Some men’s fragrances that feature Iso E Super® are Dior’s Dune Pour Homme, YSL M7, many of the Armani men's fragrances, CdG 3, Celine Fever Pour Homme, to name a few. Quite simply, it's in many classic designer fragrances of the last 36 year and in a large number of niche fragrances; Cashmere for Men by Cristiano Fissore is one that comes immediately to mind. I am sure others could name a lot more if hard pressed. It's certainly in Dior Homme Cologne, and I am pretty sure it's used in Dior Homme EDT and Dior Homme Intense.

    My apologies to those who like to imagine that niche fragrances necessarily contain higher amounts of "pure essences" and less aromachemicals. The startling percentages of Iso E Super found in fragrances like Poivre Samarkande (70%) and Tauer's Incense Extreme, not to mention a large number of the fragrances in the Serge Lutens line, should really get people thinking about the facile, unproductive dichotomy between niche and designer, something I've been arguing for a long time now. See the_good_life's post below (post #49) for a list of fragrances that contain high percentages of Iso E Super.

    Is it listed as one of the ingredients on the fragrance box if it's used in such high amounts? If so, is there a chemical synonym for Iso E Super? I don't remember seeing "Iso E Super" listed as a specific ingredient.

    Thank you for the excellent thread and posts. This is a fascinating topic.

    I have some trouble with Iso E Super--mostly I get headaches if the quantity is very high. I think Kenzo Amour also has a very large amount, but I am able to wear it if I don't apply heavily. And I am pretty sure that Hermes Vetiver Tonka has a huge dose of it, because I got a splitting headache when I wore it. Same with Terre d'Hermes. I was wondering about the OJ line--I tried a couple and they seem to have that tendency for me also.

    There is another chemical that smells like ammonia to me, and I can't figure out what that might be. When others mentioned AdP Colonia Intensa and Dirty English, I really perked up...but I think it is not the Iso E Super, otherwise a huge number of fragrances would smell like ammonia. I am starting to think it might be ambroxan. However, it seems to mostly happen when I smell fougeres, so I am wondering if there is a synthetic "fern" chemical that is the culprit.

    Help, scentemental!

    I would like to help Asha, but I have never got an "ammonia" like smell from anything I've smelled. More than likely, it might be an idiosyncratic way you are reacting to something in the fragrances you mention. If you suspect Ambroxan, why not sample Escentric Molecules Molecule 01 and Escentric 02, both of which feature Ambroxan front stage.

    Heya Scentemental,

    I am curious what other chemicals behave like ISO E Super, chemicals that are too large to be constantly detected. Specifically, are there any that smell more like laundry detergent? I'm curious as to what L'Antimatiere is made of - as I'm sure it is made of these "too large to smell constantly" chemicals (is there a specific name for chemicals of that size?) - but it doesn't have the woody, cedary characteristic of ISO E Super, but smells more like a fabric softener with a definite dose of (I presume synthetic) ambergris. Are there any ambergris aromachemicals that are too large to smell constantly? Whatever is in this stuff it's ridiculously strong to this nose. Its fuzzy musk drydown lasted over 76 hours and throughout 3 showers.

    Btw, I find it *really* fascinating how you are exposing niche frags for what (many of them) are. I've smelled a fair number of niche and many designer frags, and I really don't detect a significant quality difference between most niche and the best designer frags*. Of course, there are a number of overly 'synthetic' and rough designer frags out there and the niche brands worst tend not to be as bad as the designer's worst, but there really is not a significant quality difference in most cases.

    *(MPG is a definite exception here as their higher use of naturals is quite evident. Creed too, although to a lesser degree.)

    How weird--I just smelled Escentric Molecule 01 the other day, and I thought "nondescript woody that disappears almost instantly". It vanished completely from the smelling strip after an hour.

    So does this suggest that it is a compound that in not intense in itself, but has a dramatic effect when added to other things? Like the monosodium glutamate of fragrance!

    Perhaps not. The impression I got from the strip did not make me want to put it on my skin. But I'll try it.

    There are some very interesting questions here SculptureOfSoul. I don't have time to put together a response right now that would do justice to such questions, but I will post a detailed response when I get some time.

    I am happy to hear you find the demystification of niche fascinating. It's amazing how much resistance and personal animosity those of us interested in such demystification have encountered over the years. It took me and some others two years of relentless posting just to get Creed heads to feel even remotely self-conscious about sounding like Creed advertising copy every time they said something about Creed. I think with the inevitable proliferation of knowledge and information out there and with people like yourself who have experience with essential oils and absolutes a lot of the uniformed shibboleths about niche fragrances will mercifully fade away. At least, I hope so; although, I won't hold my breath. I see the proliferation of many blogs and blog reviews these days as free advertising for both designer and especially niche fragrances. Very little of it is well-informed or even illuminating on anything but the most superficial level. Again, to me, at least, it sounds like advertising copy for the respective designer and niche houses. I think Chandler Burr's excellent book The Perfect Scent unflinchingly exposes just how little veracity there really is in fragrance company advertising and "information releases" these days or, in fact, how little there has been since the beginnings of the industry.

    E-01 works much better on skin, and then not just sampled but fully worn, then it does on paper.


    Scentimental - I love having you on this board. Your knowledge is very helpful.

    Is it possible that Iso E Super reacts differently on different skin? I happen to enjoy E-01 (I'm in the minority, I know), and I love Poivre Samarcade, but I don't get the 'intensifying' effect described by other people. In fact, with Poivre, my main complaint is that it's not strong enough and needs better longevity. I don't have those problems with E-01, but I'd just credited that to perhaps the concentration of the non-Iso E Super components.

    Any insight into the reaction between this aromachemical and skin would be appreciated.

    I personally love E01, but if I wear it, I can't apply any other fragrance for at least 24 hours afterwards. I think the issue is not with peoples skin, it's with the sensitivity of a persons nose to the intensifying effect. At least this is my sense of it.

    Haven't had the pleasure of sniffing a Profumum or SIP yet, although I'm *sure* the SIP's smell quite natural as they are all natural .

    And I don't mean to imply that I think Creed or MPG utilize naturals in truly significant quantities. My guess is < 20%. I think with MPG they are just formulated to be rougher and smell more "natural" - but their longevity and strength (especially longevity of certain naturally fleeting notes) expose their synthetic nature.

    I hate the stuff. It drives me nuts how it is in almost everything released these days. It is just like MSG - once I noticed it in food it really started to irritate. It is the partly the feeling of being hoodwinked into thinking something much more complex is going on. It is the main reason that T d'H smelled blah to me.

    Thanks to scentemental for a detailed exposure of this aromachemicals use - I was aware of its higher than normal use in TdH and many Lutens fragrances but the Poivre Samarcande statistic was a shocker. Scentemental, any ideas how liberally its used in Guerlain Homme

    Help, scentemental!
    Asha, I'm so glad that you were willing to share your personal experience with headaches from Iso E Super®. I have a friend - a fragrance lover - who cannot stand certain perfumes which give her - exactly as you describe - a splitting headache. She is not a migraine sufferer, nor does she get headaches from other environmental causes. She says that she can sometimes tell if a perfume will give her a headache by the smell alone, but usually she tests this emipirically by a few whiffs. She did not get perfume headaches as a child or young adult, but she finds that modern perfumes give her headaches more often than not. She has gravitated toward fragrant oils and away from alcohol-based perfumes for this reason.

    Here are the structures of (1) Iso E Super®, (2) Δ9-THC, and (3) Incensole acetate (the latter is a neuroactive/psychoactive terpenoid found in frankincense). Although not all that similar in their specific structures, my point is simply this - it's not unbelievable that a bicyclic terpenoid of roughly similar size and structure would have a minor side effect such as headaches in some part of the population.



    The ammonia smell could be an amine, or (as scentemental suggests) an idiosyncratic perception of something which could be an amine or not. I recall the chemical Martima® ("wet dog smell") being discussed on the note identification thread. That is an example of an amine. Indole and skatole are more well-known amines in the fragrance world. Since amines are generally strong aroma substances, but (at least in my opinion) typically unpleasant, they make good suspects in this case. Martima® is described as fresh air, ozonic, and marine - presumably in small amounts where it doesn't reek of wet dog hair. I can't tell if there is any Martima® in Dirty English, but it wouldn't surprise me.

    I did look at "fern" chemicals - picking on oakmoss as a likely source since it seemed like the most complex component of fougères. These chemicals appear to be mostly phenolics (which are not amines). If these are the culprit, it could be that you perceive them a bit differently (more like amines or ammonia).

    Interesting thread, people. I was particularly struck by the prevalence of Iso E Super® in so many places and in such large amounts. Thanks for that info, scentemental.

    Thanks so much Redneck! I really hope to get to the bottom of this someday.

    I have been keeping a list of fragrances that smell like ammonia to me:

    Juicy Couture Dirty English
    Caron Pour un Homme
    Acqua di Parma Colonia Intensa
    Bois 1920 1920 Extreme
    Nasamotto China White (drydown)
    Parfum d'Empire Iskander
    Serge Lutens Gris Clair
    Montale Red Oud
    Perfumes Raffy Mogul
    Guerlain Vetiver (new formula...drydown)

    Dirty English and AdP Colonia Intensa are extreme offenders. I wonder if I am hyperosmic to something, such that I smell ammonia rather than what most people typically smell. Could be an overdose of IsoE, but as I said, I have other frags with IsoE and they are fine if worn with caution. I noticed my Tide laundry detergent does it also (when the clothes are wet), so it must be something synthetic.

    For what it's worth, I am in agreement with your friend. When a fragrance smells like chemical cocktail, it is rather unpleasant. Add a headache to that, and you have a fragrance that is more of a nose assault.

    EDIT: PS, natural oakmoss is a bit irritating, but does not smell like ammonia. I smelled synthetic oakmoss in the note identification project, and did not get any ammonia.

    EDIT: PS, natural oakmoss is a bit irritating, but does not smell like ammonia. I smelled synthetic oakmoss in the note identification project, and did not get any ammonia.
    That's awesome, Asha! Nothing like a crib to break the code! (I sometimes jokingly call it "differential aromanalysis" ) With that list of fragrances, it should be possible to isolate the offending note and possibly what produced it. I have Mogul and Dirty English samples, and plans to sniff several of the others. I'll get cracking on it.

    The Tide may be a hint, or it could be a red herring - some olfactory chaff. When researching wet dog smell earlier, it was clear that it's a complex natural accord, which bears striking resemblance to the odor of Martima® (or vice versa), but is unrelated. Martima® also smells like wet cardboard, damp ground, and a bunch of other wet-n-stinky things. Wet clothes was one of the things that Indie Guy likened it to. But before thinking that it must be Martima®, I should mention that perfumes are often added to cleaning products to remove the scent of amines, so adding wet clothes smell to Tide would probably be a rather self-defeating exercise!

    Wow, thank you so much for taking and interest, Redneck!

    I did read in The Guide that there is an aromachemical that can smell like urine to a small percentage of women. I have not been able to find that passage again, but I will keep looking.

    EDIT: I still have Whisperingleaves' single note swap package, so I can smell some individual synthetics. It has IsoE and Ambroxan to start...

    Is it true that Versace Eau Fraiche has a large does of Iso-E Super ?
    Cause Eau Fraiche smelled literally like nothing on me.
    And normally I can pick apart scents, synthetic or natural, very well.

    The timing of this thread was perfect. I had a meeting with the lady I mentioned this morning, and casually suggested she sniff a fragrance of mine (TdH) to see what happened. [It was a blind study, but not double-blind. ] She got the headache in under 15 seconds. It cleared 25 minutes later. I noted several subconscious behaviors during that time, (motions, facial expressions, difficulty reading and concentrating, etc.) indicative of a headache.

    She also told me that there is a fragrance which does NOT give her one. Estée Lauder Cinnabar.

    Interesting point, Dullah. I will try out Versace Eau Fraiche today - perhaps I'm as much of an "olfactory MSG" lover as I am of the other one.

    Dullah: I'm 99% sure Eau Fraiche has a large quantity of Iso E super. It would be nice to get some confirmation from a chemist or perfumer on this though. This isn't a bad thing - it's actually what makes it so enjoyable... As long as the Iso E Super doesn't give you a headache. TdH is amazing for me, until a few hours in, when I get annoyed and feel like I'm in a chemical cloud - so I don't wear it.

    I have been keeping a list of fragrances that smell like ammonia to me:

    Juicy Couture Dirty English
    Caron Pour un Homme
    Acqua di Parma Colonia Intensa
    Bois 1920 1920 Extreme
    Nasamotto China White (drydown)
    Parfum d'Empire Iskander
    Serge Lutens Gris Clair
    Montale Red Oud
    Perfumes Raffy Mogul
    Guerlain Vetiver (new formula...drydown)

    Dirty English and AdP Colonia Intensa are extreme offenders. I wonder if I am hyperosmic to something, such that I smell ammonia rather than what most people typically smell. Could be an overdose of IsoE, but as I said, I have other frags with IsoE and they are fine if worn with caution. I noticed my Tide laundry detergent does it also (when the clothes are wet), so it must be something synthetic.

    Asha, I faintly remember reading a post where you mentioned a cinnamon floor cleaner smell in (I think) some L'artisan Parfumeur fragrances.. Well I get this too, and it's really weird because L'artisan boasts a high percentage of raw natural materials. Does anyone else get this too? Have you figured out what chemical accounts for that off-putting smell?

    I don't know but I don't smell much if anything natural in Timbuktu. I don't think L'Artisan universally uses a high level of naturals.

    L'aventurier...I don't know what the cinnamon floor cleaner chemical is. I have noticed it in quite a few L'Artisan's and Diptyques. One I tried recently was Tea for Two. It starts great, but then dries down to that floor wax smell. That note is more nauseating than anything else, although it can give me a headache too.

    Cinnamon wax fragrances:
    L'Artisan Tea for Two
    L'Artisan Safran Troublant
    Lancome Cuir
    Lancome Magnifique
    Estee Lauder Sensuous
    Guerlain AA Figue Iris
    Kenzo Amour Indian Holi

    While I'm at it, here are fragrances that have a hairspray note:
    Estee Lauder Private Collection Amber Ylang Ylang
    Balmain Ambre Gris
    Coty Wild Musk (modern formulation)

    This morning I put some diluted Ambroxan and IsoE on cotton pads to smell them. Got a headache (no surprise), but neither smelled like ammonia on the cotton. I did not try them on skin.

    Far more interesting thread I ever read in BaseNotes.

    Excuse me for posting an off topic question, but reading so many interesting comments by fellow Bnoters, I would feel guilty if I would skip this chance: is there any technical book / reading material or whatever on a guide on aromachemicals and natural ingredientes and their use in the cosmetic industry?

    Should you think I should post this question in the Industry section, please do tell me that I will folow suit. And excuses in advance to the moderators.
