ok so I'm confusing myself here snd being relatively new I'm just going to ask for clarification
adding superfat -
When using a lye calculator (i happen to use Soapee) - I put in the desired super fat (i.e. 3%). Now - the amount for oils that they give include the extra 3% already? So if I wanted to say have Shea butter as my super fat I would include that in my percentages that I input into the calculator?
ok so my tired mom brain is having a hard time articulating so lets skip to an example with numbers.
So for 100g batch 52% stearic acid 48% coconut oil - I input those into the calc and get 52g SA 48g CO and the respective amounts of KOH and water. Now if I add an additional 3% of the oil weight in shea butter (3g for this example) at the end with my glycerin/EO have I now added 6% superfat (because I ticked off the 3% super fat function in the calculator)
I guess what confused me is reading through some people say they reserve X amount of whatever oil for the end after the cook for superfatting and others word it as they add 3% superfat at the end.
:-?
Whatever superfat you set is already included in the lye calculation. In your example, if you change the superfat rate and recalculate, you'll see the water and lye amounts change, though the oils will stay the same. You can add your specific SF by adding the shea to your ingredients at whatever SF you've set, then wait til after your cook to mix it in.
