Hi. I tried buying wax solution to no avail (without ordering from the US). I would like to avoid solvents so I did a 5 minute google "research". It turned out borax can emulsify beeswax. Since I have no impulse control whatsoever I made some emulsion.
I'm gonna test it in my machine later. A bit thicker than water, like cream.
What I did was:
-one part bees wax
-one part 10% (by weight) borax solution. I used tap water, probably better with distilled.
Heat both, until the wax has melted in a water bath. Recipe said to 70 degrees centigrade (no idea what that is in freedom units™️) but my wax melted at 78 degrees. In a third likewise heated container mix the two under vigorous stirring. Keep stirring until 40 degrees centigrade.
Obviously it's an emulsion, just gotta test if it's good as a wax.
Please try and see if it works for you.
