Nature seems to think PVA might not be a good thing? 🤷♂️ Doing an internet search gives mixed results, as well as what kinds like some astroturfing from the industry that manufactures pods. Wikipedia says it’s the same thing as wood glue just as you mentioned, and has been used in bookbinding for a long while. Is that good or bad, I dunno. People used to put lead in paint and arsenic in wallpaper too. I don’t know enough about it to make a judgment call.
all those dissolvable pods are made out of Polyvinyl Acetate, the same thing that elementary school glue is made out of.
Powder just gives a better wash because its ability to 1) fill the cup with more and 2) have some dispensed in the initial rinse cycle.
