Trying to duplicate a trumpet cleaning solution that isn’t available on the market

There is a product called “Herco Spitballs” which are small foam cylinders soaked in solution which are used to clean brass wind instruments like trumpets. The “Spitball” is inserted into one end of the horn and then blown through the entire instrument. The solution runs out long before the spitballs do, but the solution is not available. I’ve written to the manufacturer and haven’t gotten a response. The solution is .5% Amine Polyglycol Condensate, .5% Isopropyl Alcohol, and 99% inert ingredients (probably water). I need to know what Amine Polyglycol Condensate is and where to get it. I don’t need much. 8 ounces would last for years. Can you help me to find some?
