Soap Making 101 – Making Cold Process Soap

Have you ever wanted to make your own “personalized” soap using your favorite herbs? We’ve just discovered a great tutorial!

There are a few methods of making soap and this one is called “cold process” – meaning, obviously, that no heat is required.

It’s important to note that soap making is not the easiest DIY recipe out there. I would call it somewhat ‘advanced’ – not because you need some esoteric herbal knowledge, but because you need to be able to measure ingredients very accurately (using a digital scale), and because you will need to be diligent and impeccable with safe practices owing to the materials you will be handling. There’s some actual chemistry going on when soap is made so you will need to be “scientific” about it.



The tutorial is really well put together and includes the essential safety tips. This part is very important because soap making requires the use of Lye, which is a caustic ingredient. So, this tutorial is not advised for kids – also you will need safety goggles and rubber gloves because you really don’t want to get it in your eyes or on your skin. You will also need to use a well-ventilated area as fumes are given off – and it is advisable to have a set of utensils that are dedicated to this purpose, so that they don’t get used for anything else.

One of the great benefits of making your own soap is that you can use your favorite essential oils and skin oils. The tutorial gives you first the “plain” recipe, and then leads you on to how to make the custom blends.

    Love the idea of making my own soap.

    Very simple and easy to follow tutorial. I like the idea of a ‘cold process’ for soap making. First I’ll be making soap with rendered hog lard (about 30 lbs pre rendered weight). Maybe my next batch will be cold process. Just waiting on cooler weather to start the rendering process. Thanks for sharing your tutorial.

    Have been seeking a site to make natural soaps for the body and soul.

    This is not really making soap from scratch like our grand parents and great grandparents on the farms did though. What I have seen is that most people who make soap really think they are doing something the old fashioned way. Boiling pig’s fat and lye for days in an out side fire. No one know’s how to do that any more.

    You will need to heat the oils to 90-125°, same temperature as the lye/water solution. Some heat is involved in cold process soap making.

    What is lye? That sounds like something I don’t want in my soap. Is there an alternative?

    Lye is a substance used in the manufacture of most soaps. It is caustic but during the saponification process it is converted to a non-caustic substance. The only way it would be dangerous is if incorrectly handled during preparation, or if the measurements were performed incorrectly. Making your own soap requires adherence to safety procedures. If you are not comfortable with this, don’t do the recipe. There are “melt and pour” soaps which may not contain lye and you can look these up.

    All soap contains lye. U can’t make it without it. Melt and pour is already premade. U just melt it and pour with your additions without the need of having to handle lye.

    Harvelyn, I remember making soap that way with my Grandma, standing outside with a huge iron pot over a fire. Clean us it did but it wasn’t necessarily good for the skin. :)

    The easiest way I have found to render lard is to put the fat on the crock pot. Don’t add water or anything. Put the lid on and walk away for 6 hours.

    I’ve made lye soap many times in my cast iron pot in the yard using hog lard and lye. Yes, please be careful measuring and pouring the lye. Making soap is very rewarding, and if made correctly, can be very healthy and safe for your skin. My soaps are a 7.0 ph balance, perfect for skin. Not everyone has a cast iron pot that makes a double batch (about 30 bars), so you can make cold process soap in the kitchen. Again, please be careful will the lye. If you want to add essential oils and herbs to your soap, you need to make the cold process soap, because the hot process in the yard evaporates the oils. They should be added at the end right before you pour into the molds.
