ok, can i get the fatty acids cheaply? old baldy gave me a link to get oleic acid, which is either 4 or 10 dollars a gallon. can i get other fatty acids?
I can't imagine getting reasonably pure oleic acid for 4 to 10 dollars a gallon. I'd have to see some serious evidence for that! Old Baldy, are you out there?
You can buy most any fatty acid you want from a chemical company (assuming you have an account with one), but you'll be shocked at the typical prices of those things. For example, one price I saw for GLA (gamma-linolenic acid, the most potent 5a-reductase inhibitor of them all) was something on the order of $20-$30 a gram, if I recall correctly. Others like LA (linoleic acid, which isn't as potent as GLA) are much more reasonably priced.

revivogen is expensive, and i think it is more diluted and less effective than the fatty put on the head after a shower.
Revivogen is fairly expensive, but it's nowhere NEAR as expensive as what you'd have to pay if you were to buy fatty acids (at least certain ones like GLA) directly from a chemical company. OTOH, if you shop around carefully, you _might_ be able to find a compromise like linoleic acid which is a bit cheaper than Revivogen.
What the makers of Revivogen do is de-esterify natural oils (like flax or borage)
en masse, without making any attempt to further purify the resulting free fatty acids. That saves a TON of money!
The fatty acids don't have to be PURE, they just need to be in their "free" form. So if you were to buy each individual fatty acid found in Revivogen separately from chemical companies and then mix them back into a similar product, it would cost you a LOT more than what Revivogen costs.
BTW, Revivogen is about 40% fatty acid, IIRC. I have no idea what you mean by that part about putting something on your head after a shower.

do you think i could use the fatty acids to make a spironolactone cream?
Maybe, maybe not. The problem is that the more effective fatty acids are the ones that are the more unsaturated. But the highly unsaturated ones are a lot less stable in storage, because they're so prone to oxidation. Revivogen has added antioxidants like BHT and tocopherol. I suppose if you were REALLY careful about adding such antioxidants to your own cream (BHT, NDGA, or whatever), kept it refrigerated, and used it up in a timely fashion, it might be ok.

i wonder if there is a chemical reaction I can use to separate the fatty acids from the glycerol, and not have harmful bi-products.
My understanding is that there are certain enzymes which can stimulate the de-esterification of oils, but I don't know any specifics. Several years ago I communicated by email with an engineer at a chemical company in Norway which de-esterified natural oils, and she told me that they heat large amounts of the oils under pressure, which causes them to de-esterify. They skim-off the glycerol at the top, leaving the fatty acids in their free form below.
Got an old-fashioned "pressure-cooker" in your kitchen? _I_ do! :wink:
