Is there an easy formula to decide the pounds of soap a recipe will make?

I believe it's based on the total weight of your oils.

I believe that to be true ... the weight of your oils. I just received my 4 lb logs and I made 2 batches and made the total of oils and water to equal just over 4 pounds and guess who didn't have full molds. Duhhh, the light came on. Wish I'd found this forum first. Oh well. I'm on a live and learn project today ... new home, new oven, new molds, new recipe ... WOW !! I live dangerously don't I ?? LOL

It depends on your recipe. For instance, if you want to make a 3lb recipe and you have a recipe like this (this is just off the top of my head so I have no idea what the numbers would be or the properties the bar will have. It is just for illustrative purposes):

40% olive oil
15% coconut oil
15 canola oil
15% palm oil
15% palm kernel oil

You would figure your recipe this way:

3lbs converted to ounces is 48 oz. You then take the 48 oz and multiply each percentage amount, changing the percentage to a decimal, with the 48 oz.

Example
40% olive oil would be .40 x 48 = 19.2
15% coconut oil .15 x 48= 7.2
15 canola oil .15x 48= 7.2
15% palm oil .15x.48= 7.2
15% palm kernel oil .15x48= 7.2
Total 64 oz.

You would do the same calculations for any size recipe. Just convert the weight of the recipe to oz and multiple, change the percentages to decimals and multiply the decimal amounts with the total weight of the oils and butters. I hope that made sense.

Now if your mold holds 4lbs, you will also have to account for the lye/water solution. But this is how you can figure out and resize any recipe.

My head hurts from all the math!! STOP you are killin me

It really isn't that much math or that hard. Trust me, if I can figure it out, anybody can figure it out.

Who woulda thunk soaping was math & chemistry :roll: ?

Yea, What CP Soaper Said LMAO!

She has it down good.. I just use my Soapmaker software.
