Re: Re-distilled Ethanol

[Guest guest]

Hi - will be really interested in answers to this. I have some

'perfumers ethanol' from GoNative -

I don't understand exactly how their denaturing process works either -

although it sounds different from what you have.

They wouldn't be allowed to sell it unless it was denatured.

Perfumers alcohol is ALWAYs denatured. The only way you can buy straight

ethanol is by getting an alcohol license yourself, then you can buy

directly from chemical suppliers.

If you are just starting, it's probably best to just buy denatured

perfumers alcohol to experiment with!

They don't actually say anything about what it is denatured with, merely

how it is originally produced.

Yes I thought it must be de-natured.

I think I will have to call them again and dig a bit deeper, don't think the

receptionist person who answers the phone knows that much about it in all

honesty..

If it's de-natured with a natural essence/ingredient, would that make it ok for

natural perfumery? Or only if it's not de-natured?

I think I will use it anyway, as it would be too difficult to acquire pure

ethanol at this stage. I usually make solids or jojoba based perfumes but would

definitely like to try some made with alcohol as I haven't done this before.

Obviously I want to make natural perfumes though.

Would I not be able to call it a natural perfume if I use this?

Oh, and I forgot to ask, what does re-distilled actually mean? I mean I know

what distillation is, but what does it do to the ethanol?

Is all de-natured ethanol re-distilled?

Good Morning ,

When such cases that concern perfumery science reveals itself and is been

misconstrued, I feel obligated to comment. Ethanol as you may already know is

invaluable in perfumery. Having the numerous properties as a agent that

disperses absolutes and EOs coupled with its great polarity makes it even more

indispensable. The production and sales of ethanol is graded by its strength;

its ability to dissolve compounds in solution.

Denatured alcohol/ethanol is indeed re-distlled alcohol provided its processes

are carried out in the lab under standard conditions. Depending on your choice

of strength each could be re-distilled to obtain even a better strength as seen

in the ethanol absolute which is 99%.the entire concept is to remove the most

possible water from it. I remember my experience with my associate professor

before graduation when he would tell me to prepare a solution with the best

alcohol possible. Because of my inexperience most times I end up wasting the

little he gives me to work with until he told me when in his absence if ever

need of a better alcohol, I should re-distill the one at my disposal.

Although I haven't tried doing this myself because absolute alcohol is readily

available here in Nigeria but in theory its true and such is in practise.

I suggest you inquire of the sales person the actual grade offcourse that will

be most useful for you in your blends.

Oloruntoba,

Thank you for all the details.

I enjoyed all of the threads regarding Redistilled Ethanol.

Ethanol can be made from corn, also known as corn liqueur. It is booz. The first

distillation yeilds about 43% (in booz it is referred to as 86proof) alcohol

with the balance being water. When it is redistilled more water is removed and

the concentration of alcohol increases. The richer or higher the concentration

of alcohol the better it will dissolve essential oil, concretes and absolutes.

Here below is what I found on the subject of denatured alcohol.

I hope this helps.

 Denatured alcohol

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Denatured alcohol is ethanol that has additives to make it poisonous or

unpalatable, and thus, undrinkable. In some cases it is also dyed.

Denatured alcohol is used as a solvent and as fuel for spirit burners and

camping stoves. It is also known as methylated spirits, especially in Australia

and New Zealand. Because of the diversity of industrial uses for denatured

alcohol, hundreds of additives and denaturing methods have been used.

Traditionally, the main additive is 10% methanol, giving rise to the term

'methylated spirit'. Other typical additives include isopropyl alcohol, acetone,

methyl ethyl ketone, methyl isobutyl ketone, and denatonium.[1]

Denaturing alcohol does not chemically alter the ethanol molecule. Rather, the

ethanol is mixed with other chemicals to form an undrinkable mixture.

Different additives are used to make it difficult to use distillation or other

simple processes to reverse the denaturation. Methanol is commonly used both

because of its boiling point being close to that of ethanol and because it is

toxic. In many countries, it is also required that denatured alcohol be dyed

blue or purple with an aniline dye.

The tax-exempt status for denatured alcohol dates from the mid-19th century.
