These formulas for cold process soaps that I have done, are vegetable olive soaps because I have used olive oil as soft oil in most formulas. I use olive oil pomace type (English), orujo (Spanish), sansa (Italian), and here in Brazil I think is called refined olive kernel oil. The pomace type oilev oil is extracted from the last stage of olive oil and is typically used with solvent extraction, which is then distilled and eliminated. It is an edible oil, used in industrial kitchen and have low commercial value. Purists may even dislike this type of olive oil but is the same that is used in the manufacture of the famous and secular Marseille soap, whose oil pomace, in most cases, comes from Crete and Malta. IMHO, I think overkill and wasteful use of extra virgin olive oil to make handmade soap. The pomace serves very well for this but in Brazil is still an expensive oil.

If for cost reasons you want to exchange the olive I recommend sunflower oil, which can be changed without any change in the formula, both have almost the same SV. Of course, emollient and moisturizing properties of olive is better.

In goat milk soap the liquid used for lye solution itself is the goat’s milk in place of water. Can be used fresh pasteurized milk, hard to find, or powdered milk or long life. In all cases, special care is needed to prepare the milk with lye. If you normally  there will be a very intense reaction and ammonia release and the the soap will be a very dark brown. It must be semi-frozen milk and keep adding little lye and stir. The temperature can not rise above 30°C. Sometimes it is necessary to use ice for the temperature did not rise much.

The soap olive100  is made solely with olive oil. It has excellent properties inherent to olive, extra hydration. You can only make a cold process soap with olive 100% if you use beeswax for a good lasting. Do not ask me why, because I do not know, but it gives a good hard soap and drying with normal three weeks. I found this in the Sun Feather, reading the composition of olive them.

Cold process soaps formulas

These formulas are originally an Excel spreadsheet as well practice. Once the composition of oils and soap is calculated on a calculator (see here) the quantities of lye and water, you fill the lot size that you want to do, and the spreadsheet calculates the amounts of each component. If you have data of raw material costs, you can have the cost of each bar (you choose the size of the bars), as well as a cost analysis of each component. If you want, you can download the Java program that I made to make the pricing: Price. In the download page I put a spreadsheets available to download which can serve as a template if you want to use: Template
