I am finding that soapee.com calculator rather confusing, so many options.
Why would I not adjust for water in oils?
I do not understand which to use, 25% lye concentration or water percentage
Why does it not allow a total batch weight input, only total oil weight?
Superfat after cook or not iI cannot find any reason for before or after cook anywhere
Fragrance oil is in little 10ml bottles, so I have no idea what weight, although I suppose I can somehow try to wiegh fragrance oils, but that seems very cumbersome.
Totally confused and a little overwhelmed by that site.
I'll try to quickly break down a couple things for you. I know it can be confusing at first.
Step 1 - Solid or liquid soap? Pretty self-explanatory. Solid soap, as you're just using NaOH to make hard bars.
Step 2 - Recipe units. There's some personal preference in here. I like to use grams because they're the smallest unit of measurement and thus, a little more accurate. As for "adjusting oil weight to include water..." - personal preference. Some people like to go by just their oil weight, or do the calculations themselves. In your case, I'd tick the box and set "Oils total" to 2lbs (or other unit of measurement you prefer).
Step 3 - This can be confusing. I prefer to use "Lye Concentration". It's easiest to think of it in percentage terms that add up to 100. So if you're using 25% lye, you fill the rest of your 100% with water - so 75% water. 25% Lye Concentration is considered high water. The highest concentration you can achieve is a 50/50 solution (50% lye / 50% water). Any higher, and the lye won't fully dissolve. People use different lye concentrations based on personal preference and different recipes. A Lye Concentration of 25-30% is good for a newbie making a balanced recipe or doing hot process. You can ignore the "Water Discount" box.
Step 4 - Superfat. 5% is standard. Ticking the "Superfat after cook" box will add a little row to your final table telling you, in grams/oz/lbs, how much oil to add after the cook for your superfat.
Step 5 - Fragrance. Most sellers will put the maximum usage rate (in percentage) on the website description, so you can use that as a guide. Even if you go by percentage here, it will give you a lbs/oz/gram value in your final chart below.
Step 6 - Pick your oils, click the little plus button and more boxes will appear. Don't worry about the "Selected Oil Properties" - that's just a reference point for you. You will want to fill in your "Recipe Oils" box with the percentages of the oils in your recipe. 40 Palm / 40 OO / 20 CO (if that's what you wanna go with).
Once your oils add up to 100%, your recipe will appear below. It'll give you the gram/oz/lbs for everything that will go into your pot.
