Here’s a script for you:
“Putting gasoline on a horse’s feet as a hoof hardener is not a good idea because (insert reasoning)”
Volatile hydrocarbons tend to be extremely desiccating - applied to the wall, they tend to cause disassociation of the strands of epithelial cells that comprise the straum medium on its distal periphery (aka, “hoof hairs”); applied to the solar surface, they tend to cause flaking and spalling of the exfoliating sole and insensitive frog, thereby greatly reducing ther protective properties.
Now wasn’t that easy? :winkgrin:
Yes’m. Chem 101 - and more’n 50+ years watching race trainers play at chemistry.
If you can though take a step back and see that for the average person, Venice Turpentine, formaldehyde and Stockholm tar and so on are all basically “nasty chemicals” and there’s no huge distinction between them.
Actually, there’s a difference beyond “huge” between them. Of the chemicals you’ve cited, aldehydes (of which formaldehyde is the most simple form) are the only chemicals you’ve named that form crosslinks between protein chains. NONE of the others do.
You sure wouldn’t eat any of them, and getting most of them on your skin is reason to run to wash it off. So why is it OK to paint formaldehyde on a horse’s feet, a known carcinogen, and not gasoline?
Not being in the least suicidal, I wouldn’t eat any topical: Would any rational person? There’s a vast difference between human skin and the solar surface of the horse’s hoof. In correct proportions, formaldehyde WITHOUT plasticizers is extremely reactive with the protein chains of the exfoliating sole and insensitive frog and initiate crosslinkage between these structures (i.e., form a crude plastic), a reaction that greatly strengthens the morphology of the affected structures and enhances their protective properties without affecting the proximal sensitive structures.
The reaction of aldehydes on protein chains is undesirable on human skin and can cause blindness on the human eye, but it’s extremely effective on the solar surface of a horse’s hoof. (When all else fails, follow label directions.)
Why Venice Turps, very toxic and highly flammable, and not gasoline? Stockholm tar, often laced with carcinogenic creosote?
I’m not much on the efficacy of Venice Turps, but I’ve been around for more’n 50 years and I’ve never seen or heard of a horse having any form of toxic reaction to it. Please cite any evidence you have that suggests the concentration of ingredients in either VT or ST has been ever cited as a topical carcinogen.
Be very suspicious of this post, I invented Durasole and I’m a principal in the company that makes the stuff. We’ve been selling it with a money-back guarantee of satisfaction since 1978. Just between us chickens, it ain’t worth it to try to mix your own stuff. :)[/QUOTE]
Thank you for your response I found your explanation very thorough and interesting!
