At one point in time, A LONG TIME AGO, water soluble fuse oils were in fact relabled surfactants, in fact, a popular one many of us later got to know as Nonoxynol 9, famous for its use as a spermicide.
This ceased when it was replaced by a polymer designed for this use. The new polymer did not foam, gel up, and was much more heat stable.

Water-soluble soldering oils at 5% solution can act similarly! I remember a PCB manufacturer client who had just switched to one, umpteen years ago, for tin-lead plating reflow, and they had a complaint from the local sewage works, about 1 km away. Foam was coming out of an egg-section sewer in an almost rigid extrusion! They sent two men with breathing apparatus up the sewer to find out where the hell it was coming from!
