Is propanol 1-2 diol 178 the same as propylene glycol?
Yes, “propanol 1-2 diol 178” is the same compound as propylene glycol and appears to be a fabricated name used in a manual for a proprietary cleaning system by Kirmuss Audio.
According to the article from Analog Corner magazine [1, p. 22] (emphasis on the footnote):

The Kirmuss Audio KA-RC-1 comes with accessories: 60 mL of an antibacterial/antistatic/antifungal spray; a goat­ hair brush applicator; an optical-quality microfiber cloth; a larger microfiber cloth (decorated with rabbits) to cover the work space; a circular felt mat to support the record during hand cleaning; a combination carbon fiber/parastatic felt brush; and a bottle of stylus cleaner.
All of this costs $870—far less than at least one competing system and only
slightly more than the iSonic machine and its inferior record-spinning mechanism.
Granted, the accessories are not costly, but no matter how you figure it, Kirmuss doesn’t seem to be in this for the money: He’s not looking to lose money, but clearly he’s not trying to make a killing.
From what I’ve witnessed, he’s more concerned with waging a worldwide war against fungus.
The antibacterial/antistatic spray is identified in the manual as a “98-99% distilled water, 1-2% propanol 1-2 diol 178 mix.” That last one is propyl­ene glycol,4 an organic solvent used in, among other things, pharmaceutical preparations and as a food additive.

4 That chemical name seems made-up, and Kirmuss at first disputed that the ingredient was nothing more than propylene glycol, but a subsequent correspondence made it clear.
