Cold process soap is made by combining oils (and butters) with sodium hydroxide, which creates a reaction called saponification. It’s a straightforward process but there are very important safety considerations which we cover in detail.
The types and amounts of oils and butters need to be carefully chosen to create a bar of soap that has the optimum level of hardness, detergency and foam. In Module 1 you’ll learn in detail about the properties that different carrier oils and butters give to soap and about extra ingredients that can be added, including exfoliants, colorants and fragrance.
Included in Module 1 is an invaluable guide to carrier oil and fatty acid properties for soapmaking. This knowledge is essential if you want to formulate your own soap recipes or adjust existing recipes.
We also provide a guide to what equipment you will need to consider for making cold process soap at home, or for small-scale production. We’ll also help you with where you can buy equipment and the importance of a clean, organized workspace.
Module 1 includes three in-depth lessons to download.
1.1 Introduction to soapmaking
1.2 Theory of saponification
1.3 Mandatory safety information
Our video demonstrations will take you through all the equipment you’ll need and important safety considerations.
Module 2 includes two lessons that will enable you to make a perfect bar of soap!
2.1 Making cold process soap
We take you through each step of the soapmaking process so you are confident to follow this process yourself. There are some very specific steps that apply to soapmaking that don’t apply to other cosmetics, and carrying them out properly is essential for successful soapmaking.
2.2 Basic soap recipes
We provide you with four of our best beginner’s soap recipes so you can make a successful batch of soap on your first attempt!
In soapmaking, recipes that might seem quite ‘basic’ can produce very reliable soaps with a good balance between hardness, detergency, foam and moisturizing/nourishing properties. Many people find a few reliable base recipes (like those we provide in Module 2) and use them exactly as they are. You can also take the base recipes and make a variety of different soaps by including additional ingredients like fragrances, colors and exfoliants.
Our video demonstration will show you step-by-step how to make your own soap safely.
Once you have mastered the recipes provided in Module 2: Making Soap, it’s time to move on to some more advanced soap recipes!
The recipes in Module 3 show how you can modify soap recipes to include exfoliating particles, detoxifying ingredients and colorants.
