Pine Tar - Calculating Lye Solution in Soapmaker 3.0

[Zonda]

Hi, I haven't been using the Soapmaker app for very long and have decided to try my hand had making Pine Tar soap. I can see on SoapCalc that Pine Tar is listed, so that it will account for it when calculating the lye solution, but how do I do that in Soapmaker? I'm stuck on how to create the recipe if Pine Tar is not an "oil" and if I list is as an "Additive" it isn't accounted for in the LS calcs. Any assistance would be appreciated.

I don't use the Soapmaker app, but I understand it can be modified and customized a fair bit. Can't you add fats to this app if they're not already built in? If so, add pine tar as a new fat and set its saponification value to 0.043 for NaOH and 0.060 for KOH.

If not, a work-around would be to hand-calculate the lye requirement for the pine tar and add that to the NaOH weight calculated by Soapmaker for the rest of your fats.

NaOH for PT = (Weight of pine tar) X 0.043

KOH for PT = (Weight of pine tar) X 0.060

If you use ounces for the weight of pine tar, the answer is in ounces. If you use grams, the answer is in grams.

Thank you very much for your answer. I've worked out how to add it as a base oil and have entered the figures you've provided.
