To allow this to form Glyoxal, I would use 40 grams of trimer and 60 grams of DW to make a standard 40% wt/wt solution. Then I would let that stand for about 2 days and then I would dilute it to working strength by taking 10 g of the Glyoxal and adding 90 grams of water to make a (10%) 4% wt/wt working solution. I would refrigerate everything after this and only take the working solution out as needed.
