    Default A question regarding the use of isopropyl myristate in perfumers alcohol

    I have just come across this:-

    "please note that there are those [authorities] who state: "do not use any variation of isopropyl alcohol, nor any so-called 'perfumery blend' that might contain it; the rapidity of the drying rate is far too high and it can carry a scent that may interfere with your blend. isopropyl myristate is known for causing skin-clogging and blackheads and it is a dermal, eye, and respiratory irritant."

    I found it here:-
    http://home.earthlink.net/~skinesscentuals/Perf.html

    My mistrani perfumers alcohol DOES have this in and I was wondering where this information came from and is it true?

    Can anyone in the know shed any light on this matter?

    Hi mumsy,

    I just looked it up and I found this:


    "isopropyl myristate
    Categories: Emollients, Thickeners/Emulsifiers
    Used in cosmetics as a thickening agent and emollient. Historically, animal testing has shown it causes clogged pores (Source: Archives of Dermatology, June 1986, pages 660–665). Results derived from animal testing were eventually considered unreliable, however, and there is no subsequent research showing this ingredient is any more of a problem for skin than other emollient, waxy, thickening ingredients used in cosmetics."

    Here's the link:

    I hope it's okay to use because I have some isopropyl myristate too...

    This is what the description was on the site i bought the perfumers alcohol from:-

    The 3 main ingredients of perfumers alcohol are:

    1. Ethanol (denatured) - A pharma grade alcohol which is the main carrier for the fragrance oils. This evaporates quickly as it is warmed by skin temperature releasing the fragrances evenly over the surface.

    2. Isopropyl myristate - used in cosmetic and topical medicinal preparations where good absorption through the skin is desired.

    3. Monopropylene glycol - a skin safe cosolvent which allows the fragrance oils to be solubilised in the alcohol carrier. This helps to control the evaporation of the alcohol so that it does not flash off too quickly.


    This description doesn't indicate anything like that.....
    One is at the mercy of the vendor when ignorance is bliss.... I hope it's ok to use too.

    It may be a good idea to summarise the sort of perfumers alcohol everyone uses and finds best. I'm finding mine a little harsh after I've blended a perfume. It blasts the alcohol smell at me instead of the scent, but this could be just I haven't had it mixed for long enough yet.

    How long are you storing your new blends for before they are smelling of perfume and not the alcohol?

    I believe Isopropyl myristate is a naturally-derived synthetic... How do you use it in formulation? In which proportion? Can we replace it by glycerin? Is there a natural substitute of Monopropylene glycol??

    I don't know the answer to that. The perfumers alcohol I buy, already has this in it. I think it must actually be to stop alcoholics drinking it.

    If it is a naturally derived synthetic, then I would rather buy one without it in if that was lawfully possible in England. I want my eventual perfumes to be as natural as I can have them within reason. I don't like the idea that there is anything synthetic in my current blends unless I wish to put it there for a reason.

    Does anyone know if you are allowed to buy undenatured alcohol in the UK? Or know of an undenatured source anywhere?

    My perfumery alcohol is Denatured alcohol and has no isopropyl myristate. I have an additive, bitrex, to make it improper to drink. Bitrex is another name for denatonium benzoate, a "harmless" chemical compound used in household products, denatured alcochol, insect repellents, shampoos and liquid soaps. I don't like to have that but no choice, it's impossible to find organic perfume alcohol, it would cost me over 100$ for a gallon with shipping, taxes and duty...

    Found more info for isopropyl myristate: used as emollient for cosmetics and medicinal formulations (usage Rate: 1-10%), but no clue how much exactly for perfumery. If it's used only for moisturizing properties and not as a stabilizer, then, I think I am going to use vegetable gycerin...

    Default Re: A question regarding the use of isopropyl myristate in perfumers alcohol

    Hi Mumsy, When getting into perfume making, the solvent (i.e. pure ethanol) is of utmost importance, and compared to the essential oils it turns out to be the hardest thing to procure. This is a major issue for DIY perfumery and I think this topic should have it's own thread, and it should be a sticky thread called "Alcohol for perfumery". I hope the editors or managers of Basenotes are reading this and that they can make this happen. If anyone reading this knows how to cause this to happen, please tell the right people.

    Here are some major topics that should be discussed in this sticky thread (along with my answers which may or may not be correct):

    1. What is perfumer's alcohol? Answer: fundamentally it's just pure 95% ethanol.

    2. Is there a difference between: a. Perfumer's alcohol, b. Grape alcohol, c. Grain alcohol, d. Everclear, etc. Answer: no. Since the ethanol in all of these is a product of a fractional distillation process, it's pure. Trace amounts of impurities may be present, but they likely have little or no effect on the end product, perfume.

    3. What is proof? Is 100 proof alcohol pure ethanol? No. 100 proof means 50% ethanol. In fact 190 proof alcohol is 95% ethanol and that's the one you want.

    4. Why is it 95% and not 100% ethanol? You cannot get pure ethanol due to the physics of the substance. This has to do with vapour pressure of ethanol versus water vapour. Due to equilibrium considerations and the nature of these two fundamental substances of nature (i.e. H2O and CH5OH) ethanol will absorb water from the air until it reaches a balance at 95% ethanol and 5% water. You can get to 100% by using some tricky distillation techniques involving benzene, but it's not worth it.)

    5. How to get 95% Ethanol. This depends very much on what country you live in. Based on a wide reading of Basenotes DIY threads it appears that in some European countries such as Italy and Holland, it's relatively easy to get pure 95% ethanol. You just buy it at the corner store and it's cheap. In other places such as England, Canada and the USA, it's a major project trying to find it legally. A list of countries and the availability of ethanol in each would be handy. For instance, in Canada it's different in each province, but on a national level you can import pure 95% ethanol when you cross the border, as long as you have been outside of the country for 48 hours and it's not more than 1 litre. All along the border in British Columbia there are duty-free shops on the American side of the border that sell "Everclear" or some similar brand of 95% ethanol for about $20/litre. NOTE: Americans cannot buy this product. Only people *leaving* the country can buy it.

    6. Making your own ethanol by fractional distillation. You can buy a still for $400. Or you can make one for considerably less. Ethanol itself is easy to create with yeast and a sugar source. The hard part is separating it perfectly from everything else.

    7. Denaturing agents. Which ones are OK for perfumery and which are not? Here in Canada some denatured ethanol had camphor in it, which is a pain because you can smell it for a few minutes after the ethanol evaporates and this pretty much eliminates this relatively cheap source of ethanol from perfumery. Is Bitrex better?

    8. What about the practice of adding a tiny bit of vanilla or benzoin into a 1 litre bottle of pure 95% ethanol to make it into "Perfumer's Alcohol"? Why is this done and is it of any use?

    Others may have other topics that they'd like to contribute. Again, please make this into a sticky thread at the top of DIY perfumery.

    bshell, that is an excellent overview. There ARE, however, a number of states in the USA that it is completely legal to purchase 190 proof Everclear. But there are also quite a few that the highest percentage that is legal to purchase is the 151 proof of it. You will have to check your local laws to find out.

    Thank you for that. It is interesting that some suppliers do add some tempering essential oils to 'condition' the alcohol. My feeling is that this is just to make it smell more pleasant, but could the alcohol then be classed as 'perfume' and therefore be legal as a result? Would this be the best way to avoid such legislation in a perfectly legal fashion?

    As I said in point 4 above, you CAN get 200 proof or 100% ethanol but the manufacturer has to use a distillation trick involving some other nasty solvent like benzene. The problem is called an azeotrope and you can read about azeotropes on Wikipedia. The way around it is called azeotropic distillation and will result in pure 100% ethanol but at more expense and trouble. And anyway, when exposed to air, the pure ethanol will pull in water from the air till it gets to 95% again. 95% or 190 proof ethanol is all that is needed for perfumery. No need to get 200 proof.

    Hi Mumsy,
    I use a range of sources for alcohol for my perfumes depending on what I'm trying to achieve - for a fully natural product the Mistrani 'Perfumers Alcohol' isn't any use, but otherwise I find it works well in most applications. If you are looking for a source of alcohol for a fully natural product then I'd suggest you have a look here:

    http://www.essentially-me.co.uk/lab_alcohol.php

    You'll notice that they sell two varieties - standard and organic - both contain some essential oils already, so they will have an influence on the scent you are using them with. The organic variety is very expensive because it's free of bitrex and so you have to pay duty on it, just as you would with a drinking alcohol.

    If you are within striking distance of Stroud I'd recommend a visit - besides the fact that they are nice people the courier charges are high on this stuff.

    Hope this helps.

    In the UK you have some hurdles to overcome: first the duty makes it expensive, second the lack of additives means you need a licence to sell it and third (and this is the killer) you also need a licence to buy it. The HMRC rules are rather draconian I'm afraid.

    PS - one thing you might try, if you can manage to work with an alcohol that is only about 80% (the rest being water) then you could buy Balkan Vodka - that's for sale in specialist drinks shops and online in the UK and has no scent or additives. It's around £35-£45 for a standard 70cl bottle though.

    Hello Mumsy

    You can buy undenatured alcohol (ethanol - pure grain alcohol - 200 proof - seriously drinkable stuff!) in the UK but it's messy.

    For many years I have held a permit to purchase and use denatured alcohol; this is fairly easy to obtain (please come back if you need the details).

    However, when I asked about a permit for ethanol, I was told the standards are very strict. You have to demonstrate: (1) your storage facility seriously secure to prevent folks from stealing it to drink and (2) your storage facility is seriously fireproof.

    Since my perfume-making was fairly small volume and only for gifts for family and friends, I decided to stick with denatured alcohol to avoid the hassle. (I tried distilling vodka to remove the water but that was a disaster.)

    Now that I want to work to a higher standard and probably a higher volume, I plan to think again about pure ethanol. To my thinking, the finest perfume should include only two ingredients: oils of the highest quality and the purest carrier available. As far as I'm concerned, you can't find a carrier of any higher purity than ethanol (there are no doubt folks out there who disagree).

    I hope this helps.

    All the best.

    Thank you for that. I suspected as much. To get any such certificate or permit here in Britain, maybe one would have to keep it in an outhouse with iron bars on and get any perfumers to sign for the keys, sign an indemnity clause and get a few million pounds insurance for a public indemnity clause. If it was in the house, no doubt it would render the house insurance invalid too. (I'm going to check that as well...having thought of it).

    I bet France didn't have any such nonsense... maybe it does now though.

    Hello Mumsy

    Well, heck it's not really not that bad. If I remember correctly, and it has been a few years, in the UK you can meet the requirements for the ethanol license with a reasonably secure garden shed: you don't really need iron bars and a concrete bunker. You could probably do it with a fireproof metal locker sited at the bottom of the garden and secured to the ground somehow.

    Again, if I remember correctly, before your license is approved they have to come to your house to inspect your storage facility. This is a bit of a hassle but now that you're getting serious about your hobby, maybe it's worth it.

    The other problem is the cost. In my last posting I talked about 200 proof or 100% ethanol. You can buy 200 proof - I think -but it will cost you maybe £600 a litre, while 195 proof might cost you £200 (or whatever the market is today).

    So I guess it comes down to the question of how serious you are about your hobby (or maybe by now for you it's more than a hobby, perhaps an avocation?). For me, I'm going to stay with my denatured ethanol at maybe £50 a litre for a while yet. When I have created something to rival Chanel #22 for the woman I love, then it will be time to think about pure ethanol.

    Or maybe, and this relates to an earlier post, with the help of somebody studying chemistry at university, you could devise a still at some reasonable cost and create nearly pure ethanol by removing the water from vodka (probably illegal but my lips are sealed. Anyhow, they might not deal with you too harshly when you convince them nobody's drinking it).

    Speaking of Chanel, do you have any idea where I might be able to buy 5ml to 10ml clear glass bottles with ground glass stoppers housed in little boxes with black linings at anything other than obscene prices?

    The information on ethanol is often very confusing and the purpose of this sticky thread is to remove some of that confusion for DIY perfumers.

    To Smellsgreat: Thanks for your contributions to this thread. I think there are errors in both your post on the cost of ethanol in the UK, as well as within your link to the Chemistry department of University College Cork. The numbers appear to be off by at least an order of magnitude. I would be very surprised if alcohol costs £600 or even £50 per litre anywhere on the planet. Here in Canada it's at least 20 times less even if you go the full legal route with permits, etc. On the University of Cork website they talk about the enzyme powered fermentation conversion of sugar into ethanol happening at 250 to 300 degrees C. This is not correct since it would have to be under tremendous pressure and this would destroy the enzyme for sure, and probably the alcohol, too. It's more likely supposed to be 25C - 30C. Also, later on they give the boiling point of ethanol as 780C. In fact it's 78.1C. Then the freezing point is given as -1150C. This is far colder than absolute zero. So the correct number is more likely -115C. Much more reliable websites for information on ethanol are the wikipedia entry: http://en.wikipedia.org/wiki/Ethanol and this one on "Neutral Grain Spirit": http://en.wikipedia.org/wiki/Neutral_grain_spirit

    Another very confusing notion regarding ethanol is "proof". 200 proof should not be used in perfumery because it contains traces of Benzene which is carcinogenic. The most anyone would use is 190proof, which is 95% ethanol, the highest concentration that can be obtained via distillation due to the azeotrope ethanol forms with water. i.e. practically usable ethanol in perfumery must always have 5% water in it. To be exact 4.4% water.

  25. #25

    Default Re: A question regarding the use of isopropyl myristate in perfumers alcohol

    Hello Bshell

    One problem solved and one to go:

    The -1150C and the 780C should read -115C and 78C; the "0" in each figure should have been a superscripted "degree" sign for which the formatting apparently was lost when the article was posted.

    The £600 I was quoting from memory was the cost of seriously pure ethanol with the remaining 5% water removed (we don't really need a carrier that pure so why worry? A little water may be good for you, anyhow). The last denatured ethanol I bought was several years ago and I don't remember exactly what I paid for it. I shall check current prices here in the UK and post a reply tomorrow.

    Sorry for the confusion.

    Hello Mumsy & Bshell

    As promised, here is an update from the UK.

    Mumsy, you can obtain a permit to purchase up to five Litres of Denatured Ethanol B from HM Customs & Excise. When I obtained my permit about ten years ago it was free; there may be a fee now.

    Ethanol B is pure Ethanol (95%) to which is added 0.1% Tert-Butyl Alcohol to make it undrinkable. I haven't been able to find any references about how Tert-Butyl Alcohol at 0.1% will affect your perfume (I should think not at this low concentration).

    You can buy it here in the UK from Phoenix Natural Products Ltd by phone quoting your Customs & Excise Authorization Number. The price quoted to me today was £4.45/L with some carriage added.

    @Bshell: Sorry for the confusion over the pricing; memory is the first to go.

    I hope this helps perfumers here in the UK and clears up any confusion.

    It would be nice to hear from anybody with knowledge of how this denaturing agent might affect a perfume blend.

    Hi everyone. Been lurking here for a while, but I thought I should share this. I recently came across some 95% Vodka that I imagine would be great for making tinctures / perfume. Still pretty expensive, but it's a UK source and seems to be the only easy way to get pure un-denatured alcohol without going to Italy or somewhere. Apparently it's popular in Poland for making fruit flavoured Vodkas and the like. Here's the link:

    Renegade: Thanks! That's a great source, but insanely expensive.

    Smellsgreat: £4.45/L is about 10 times less than the price of Spyritus Vodka at the Whisky Exchange as referenced by Renegade. Unfortunately Tert-Butyl Alcohol has a camphor smell: http://www.thegoodscentscompany.com/data/rw1047291.html. This makes it questionable for perfumery, unless of course you want that hit of camphor in your perfume. Personally, I find that when using that stuff, the camphor smell evaporates pretty fast, but it's going to be there as part of the first impression of the perfume. I find it's gone in a few minutes though.

    Recently, I found a source here in town (Vancouver) called Golden Bough Botanicals where you can get denatured Ethanol (they use Bitrex in ~30ppm quantities) and it does not smell at all. Cost is about CA$8/L which is the cheapest I have seen. They have a minimum order of $75, though. But you can buy all sorts of essential oils, bottles and other things there as well, such as fragrance-free shampoo and hand-cream bases, etc, so it's easy to spend $75.

    Thanks to everyone contributing to this thread. Finding good quality perfumer's alcohol is essential and yet one of the great unexpected difficulties of a beginning DIY perfumer. This thread should help a lot of people.

    One quick thing that no one else mentioned. Isopropyl myristate isn't a "variation of isopropyl alcohol" any more than water is a "variation of hydrogen" or a "variation of oxygen". It's a molecule that happens to have an isopropyl group attached to it. It's, systematically, an isoproyl group and a myristate group attached by an ester bond. Isopropyl alcohol is an isopropyl group with an -OH group attached to it. (Or you could say a propane molecule with an -OH group attached to its middle carbon.) The presence of a specific group in a molecule doesn't necessarily convey upon it the suite of properties of another arbitrary compound also containing that group.

    Default Re: A question regarding the use of isopropyl myristate in perfumers alcohol

    Sehrgut: that's a really good point. Maybe you could expand on what the Myristate group is, and what it does, and why we would want it or not want it in our mix. It seems that isopropyl myristate is added as an emulsifier. Is that your understanding?
