Like many of us i have glycerol piling up behind the shed, don't need gloggs as i get lots of firewood for stove so i had made some liquid soap a while back and though i would try washing some old towels that had been in a bucket with water and a mix of Noah and a little Kohl.
rinsed them first then put them in washing machine with about 30ml of my liquid soap, well the machine quickly filled with suds so i stopped the machine and put on a rinse and hung my nice clean towels.
Tonite i repeated with some work clothes and it took 100ml to get very, very little suds.
I assume that the Noah in the towels is what caused the large amount of suds.
Does anyone have any ideas as to the chemistry of making a liquid soap to use in washing machines
