I had some water lube (used for water injection in performance engines) sent to a lab to be analyzed. I wanted to try to reproduce it. I was told they found this in it: poly (random-ethylenglycol-propyleneglycol) butyl ether (random-PEG-PPG) (~1100 center mass). I'm having a hard time finding anything like this close to that center mass. Is there a simpler term, or way to communicate to someone what I'm trying to find? And where would be the best place to locate and purchase? Any help would be very appreciated. My background is automotive, and I'm struggling locating suppliers. I'm not even 100% sure I can purchase it.
