Goat milk soap May 20, 2016 09:00
I wasn't quite sure about the goat milk soap. People seem to do it in different ways: some dissolve sodium hydroxide in frozen goat milk (because the sugars in milk raise the temperature of the lye solution). Others add milk powder at trace. I have reservations about mixing sodium hydroxide with milk: how do we know whether the product of the reaction between the two still contains the beneficial properties of goat milk? Eventually I decided to add goat milk at trace.

All was going well. I achieved a medium thick trace, at which point I added goat milk and clay. And then... after a brief period of blending, the soap butter seemed to be getting thinner, instead of thicker! I blended for a little longer, but the trace was still not thickening. At that point I added calendula flowers and poured the soap into the mould, suspecting that what I've created was not soap at all and somehow milk and clay must have separated fatty acids from the lye....
When after about half an hour I checked on the soap however, it was thickening nicely. It looked really pretty and delicious: white like the milk it had been made with. I cut it and stamped it and I cannot wait to try it!
