Hey there .

I guess that this question is kinda out of your forum usual topics , but i dont know where else to ask that....

i need to know if water can make any reaction with ethanol .... you see i made a tincture of herbs with ethanol , and when i added disiltised water to that it made my skin burn like hell..... any ideas?

Thanks.

I'd say it was something with the herbs. Water and Ethanol make no reaction, other than a hydration when adding water to high concentration ethanol. Anyone feel free to correct me if they know something I do not.

Perhaps there was a scratch on your skin. Alcohol in cuts would probably burn pretty good. I know isopropyl does. Perhaps you had an allergic reaction to some of the herbs. It's hard to tell without more info. What herbs? What conc. of Ethanol? What the skin surface looked like afterwards? Anything else at all besides EtOH, herb extract and water?

i used this herbs :

green tea , capsicum (mayb this kind of herb..) , balm mint , nettle , thymus

i soaked them all seperatly in ethanol 95%
for 2 weeks , and then i have mixed them together in a seperate glass ,. after that i add the disiltised water (very small amount ) and put that on my skin ... and what i felt was a burning sensation (like after you tan alot) ... there was no redness of the skin and nothing unusual from the out side..
anything you can tell from that?

thanks.

The active ingredient in Capsicum, what causes the burning, is a chemical called "Oleoresin Capsicum" (OC) or just Capsaicin. It is one of, if not the most, irritating naturally-occuring substance. If you let it Capsicum soak in Ethanol for 2 weeks, no doubt much Capsaicin has dissolved in the Ethanol-- and in contact with skin, this would burn! In fact, pure Capsaicin can cause blistering. I would avoid this ingredient in the future for skin products .

Thanks alot for all the answers.

Just 1 more question .

i use the tinctures for a reason..trying to get rid of my body hair,... and i wanted to know if the ethanol tincture penetrates the skin and into the hair follicle , or evaporates when it contacts the skin .. and can penetration enhancers with the ethanol help , like - Dmso , Propylene glycol , Oleic acid
I just need to enter all of the active ingriedients of the herbs into the skin and i read that liquid substences penetrates better the creams and lotions

Ah, but it would make a nice improvised teargas spray if put in an aerosol can..... hmmmm.

And as for the topic: AFAIK, the only way to permanently remove hair involves laser treatment. For a quick temporary solution I would suggest *buying* hair removal cream. One's own skin is not a good lab animal.

thanks

On a related note, were you using pure ethanol or denatured ethanol (i.e. ethanol that has been deliberately contaminated in order to render it unfit for human consumption and so exempting it from liquor taxation)? If it was denatured, what was it denatured with? Some denaturants are pretty nasty and so are unsuitable for use in cosmetics.

My thoughts exactly. Use someone else's skin.

There is another procedure: Insertion of heated needles into the follicles (OUCH).

I must ask, just out of curiosity: When you "tried" laser, was it performed by a pro or did you use some kind of industrial CO2 laser?

To answer your question of CH3CH2OH penetration: I would think that it penetrates <b>if the skin is absolutely dry</b>.

When I use a special kind of deodorant in my armpits, which consists of aluminum chloride hexahydrate dissolved in ethanol, I

1) Wash the skin with a detergent normally used for washing the dishes.
2) Use a hair drier for 10min to completely dehydrate the skin.
3) Apply the fluid, rubbing it in good.
4) Try to ignore the itching for a couple of hours.

This helps absorption, and also limits the itching (which is augmented by water presence).

I think it's also proof that ethanol penetrates, since the deodorant doesn't contain (much) water, only ethanol and the aluminum chloride hexahydrate.

This was probably information that most of you could have done without, but I feel.... contributative... today.

about your question... i went to a pro laser in my country , also tryed with light... and nothing really worked on me.. so i saw articles on the herbs and patents , and said.. well why not to try that , thats my only chance to get rid of the hair

im really glad i entered this forum .

anyone here knows about the herbs ... i mean their effect on the skin and body.

I know that i need to inhibit the 5-lipoxygenase and cyclooxygenase in order to make this work....

so if anyone can tell me about the herbs that i use (in previous post) .. their good and bad effect, i will be really happy

thanks

Yes, the burning sensation definetly comes from the capsaicin, from the capsicum (which is a pepper and not a herb IIRC). Capsaicin specifically stimulates heat receptors, hence a heat sensation. That's why hot foods are called 'hot' as capsaicin really does stimulate heat perception. Alternatively, menthol stimulates cold receptors, thus the cold sensation when you have it in sweets etc.

Do you know what happens when you inhibit 5-lipoxygenase and cyclooxygenase ? what compounds from the herbs are supposed to inhibit them?

Possibly, but I think aluminum chloride is so stable that no free Al is released. I think all antiperspirants contain more or less of the compound. The one I was talking about can only be bought at pharmacies and contains 20% aluminum chloride hexahydrate in ethanol.

Stops all sweating for about 10 DAYS.

when you inhibit 5-lipoxygenase it evantually inhibit the leukotrienes, which inhibits the hair growth ,.... the 5-lipoxygenase and cyclooxygenase presents in the herbs leafs - check out : http://www.ars-grin.gov/duke/

any other comments , advice ... anything about how do you think i can make the spray , water + ethanol , only ethanol ... anything ?

Very possibly. That's my experience with many compounds. Water might act as an absorption agent, i.e. the solid compound becomes a suspension in water, and water transports it into your pores.

Btw, capsicum is, unless I'm completely mistaken, what is used in "pepper spray". I wouldn't use it on my skin. Be careful, OK? A little excess hair is much better than huge skin burns.

Edit: Oh, my 200th post! This calls for a celebration.... where did I stash that beer....

Your method (random plants and chili pepper in ethanol) is going to be pretty tough on your skin, long term, and is probably a pretty inefficient hair-removal method. You'd be much better off consulting a cosmetologist. They've been dealing with these problems for centuries, and have a pretty god idea how to do it effectively and gently.
Then again, I hear fuming nitric acid works great, and doesn't sting too bad. Try that!

Another good one is selenium - it rapidly removes your hair, but sadly not just in the applied area.... you'd look like a chemotherapy victim!
Besides that, it's exceedingly toxic, so don't even think about it!

Hey again everyone ... i really hope you can help me with this new questions...

do you know if there is a diffrence between extraction of herbs in ethanol and extraction in water ( are diffrent plant chemicals go out diffrent with each vehicle? )

do you know of any way to make a transdermal spray effectivly ? i have tinctures made of 40% ethanol and 60% water , and i wanted to know whats the best way to get them past the stratum corneum . i read that spray is the best, i also have propylene glycol and dmso ,.. do you think that can help me deliver the water and alcohol phase into my skin?

thanks.

Do <b>NOT</b> use glycol on your skin!

As for the spray thing, and the extraction, I would go with 95% ethanol.

But I still don't like the idea of you using yourself as a guinea pig in this way. At least try the mixture a few times on a mouse first.
