Hi I am trying to make a Liquid version of Oil based soap having TFM around 25-30%, when i make the batch it’s in liquid form but as it cool down it gets harder (not as a soap bar but kind of paste). what should i do to keep it in liquid form.
I am using Castor oil, palm Oil (15% of total oil Part), rice bran oil(again 15%), koh, sodium silicate, sodium xylene sulphonate, sles, non ionic surfactant, peg 400, fragrance and colour.
