Found this at Autobanter.com All you have to do is google Amor All Bad or Good.
OK, if you want a detailed chemical explanation, here goes.
Soft vinyl plastics (as opposed to things like PVC pipe)
contain a large amount of plasticizers. The one that is
almost universally used is dioctyl phthalate. It is a
relatively high molecular weight, water insoluble, nontoxic
compound. Over the course of time, the plasticizer will
vaporize and leach out of the vinyl causing it to become
stiff and brittle, which is when it cracks.
ArmorAll is an emulsion of dibutyl phthalate in water.
Dibutyl phthalate has a lower molecular weight than the
dioctyl phthalate in the factory soft vinyl. While it will
plump up and soften the plastic (good) the lower molecular
weight means that it is more volatile and more water soluble.
Therefore it will be lost more quickly to the environment
via vaporization and leaching. A nasty side effect is that
it will take the original plasticizer with it as it is lost.
What this means to the end user is that if you start using
ArmorAll you had better continue to do so, or your vinyl
will degrade much faster than if you had done nothing.
