Thanks for all of the helpful info. I think I have really hijaked this thread
. So sorry IanT.
Anyway, how do you know what percentages that you want? So...say you are ready to soap--how do you know that you want 20% of this oil and 15% of that oil, etc? Those are the numbers I am talking about. I don't know what percentage of oils that I need to make soap. I know that I have read somewhere that with such and such soap to get, for example, lather...the range is 14-42. So would I just pick a percentage somewhere within that? Sorry. I'm just not getting this and I want so much to understand it so that I get it right. I really appreciate your time and efforts in helping me to understand this.
SoapCalc may be hard to understand, unless you've done some other research first — like either reading a few soapmaking "bibles" and visiting a few sites (like Miller's and Mortar and Pestle).
When I decided I was going to learn to make soap, AND eventually sell it, I grabbed a few books, and read them, from cover to cover. THEN, I started to search online. When I would look at recipes, I began to see a "pattern" with oil percentages/amts. Meaning, Olive Oil, Coconut Oil, and Palm Oil were the three most common oils I found in soap recipes. They also made up the largest "percentage" of the soap recipe. Other oils, like Sunflower, Castor, Sweet Almond, made up the smallest percentage of the recipe.
I wanted to know why. So, I continued to research, to find out what percentage of oils should be "hard" and what percentage should be "soft" (on average). Of course, the percentages together have to total 100%. I discovered, for instance, that too high percentages of certain oils will make soap too soft, or make it go rancid quickly.
THEN I started to play with SoapCalc, because I had some basic knowledge of oil properties AND I knew the more common formulations to help me get ideas. If you play with SoapCalc, and just start entering percentages of oils, and click "compute recipe", it'll tell you if your percentage total is more than, or less than 100%. It'll tell you to add or subtract oil amts/percentages to get to 100%.
You can NOT just "figure out" SoapCalc, if you've not done the preliminary research. It won't make sense, and even if it does, you won't be able to formulate a decent bar of soap. You don't start with SoapCalc. I didn't even mess with it, until I'd read and researched books and the internet.
Plug a few recipes you've found into SoapCalc — and look at the numbers. Now, some of them will surprise you — in good and bad ways. But what you'll learn is that SoapCalc is a guide. It's not going to instantly make someone a good soapmaker. I'm experimenting with different oils, to learn how they work in a recipe, to change the outcome of the finished bar of soap. I will never know it all.
Search this forum. There is so MUCH info.
Hope that helps...
