Re: The other side of the coin, Vulcanel

Thanks for writing, I agree with most of what you said, and recant my statement that suppositories are worthless, since they could be melted and refined to recover their active ingredients (scrap value), or even taken orally, if one wanted to and could intestinally handle the vehicle, usually cocoa butter. Just from my personal opinion, which by definition is neither right nor wrong as it is just an opinion, EDTA suppositories are worthless. It is unclear that they can do anything different than the oral route can do, and given that they are on par in expense with commercial drugs, when in fact their active ingredient is dirt cheap, the cost justifiability is highly questionable.

Cichanowski's website contains a lot of good info, I mean, alot. But it also contains some mis-information too, for example: EDTA is not an anionic surfactant.
A surfactant, by definition, contains a hydrophobic portion and a hydrophyllic portion, and each surfactant has a unique critical micelle concentration associated with it. Ethylene dinitrilo tetraacetic acid does not contain a hydrophobe, and is hence not possessed of surfactant properties. Claiming it has having anionic surfactant properties is wrong, since it is obviously a hexadentate ligand and as such incapable of forming micelles.

A prudent chemist would not attempt in general to use EDTA acid, salts, or complexes to modify zeta potential. In the presence of metallic cations, it wouldn't work well at all. I would not eat anionic surfactants either, but if some wish to try, may I suggest Ivory soap for its C12 content, or Dove for its sodium cocoylisethionate content.

Blood is an aqueous colloid. Altering its properties is accomplished largely the same as for other colloidal suspensions. Makers of instruments for measuring zeta potential usually publish short primers on the principles involved. Search the internet for zeta potential meters and you will probably find such a primer quickly.
