New to Zinc Oxide (ZnO). It appears to have hardened one batch and not another. ???
#1. Castile soap: soap was harder than otherwise or at least similar with slightly over 1 tbsp ppo.
#2. Brine soap that usually hardens acceptably well because it's a brine soap and despite having lots of soft oils: soap was softer than otherwise with 24g ZnO.
Is ZnO acidic which can break and consequently soften soap, especially if it is already a little soft? Outside of changing the oils, can working around the excessive softness be a matter of quantity or method or timing of adding the ZnO?
I used apx 1tbsp ppo ZnO. What is the best percentage of ZnO ppo added to soap?
Also happy for any other stories or observations.
