I want to elaborate a small batch of goats milk soap. The oils are Olive Oil (35%), Palm Olein (40%) and Coconut Oil (25%). Goats Milk (38% of weight of total oils). NaOH weight according to a soap calculator for the oils.
The sugested process call for freezing the goats milk soap then add the NaOH in order to make the lye solution. Then add it to the oils mix at around 30°C.
I recently was advised to add half the milk for making the lye solution, then mix the rest of the milk directly to the oils. Others prefer to add the rest after trace so that half of milk's fat won't react with the NaOH.
Considering the number of operations, it is easier for me to make the lye solution with the whole milk, however, I want my soap to get the best possible from the milk's properties for skin. In your opinion, does this change in the process make a better quality soap for skin?
I apologize in advance for my English, this is not my first language.
