Cold-Process Soap Making Instructions

Congratulations! You are about to join the world of herbal soap making. Our kits include pre-measured materials for one batch of soap. These instructions, combined with our detailed PDF instructions*, will guide you through the cold-process method of soap making. At first, these instructions may seem a bit overwhelming, so read them first and familiarize yourself with them. When you make the soap, however, you will see how easy and fun this is.

*We do not recommend using this page solely for your soap making instructions. Please use the instructions that come with your soap making kit (or see the soap making instructions in a new window), as they come with more detail and safety and cleaning instructions for handling the lye solution.

Materials Required for Making SoapBefore you start, gather up all the required materials and familiarize yourself with them. You will need a heavy duty rubber spatula, metal whisk, sauce pan or stock pot, 2 gallon white, high density plastic bucket, liquid measuring cup, rubber dish-washing gloves, safety goggles, thermometer, one quart cartons, and a blanket or Styrofoam cooler. If you have a stainless steel stock pot, you can use it for both heating the oils and mixing the soap (you would not need the 2 gallon bucket if you chose this method) Last, for the stirring stage, our instructions discuss stirring by hand. However, we highly recommend using an immersion/stick blender (plastic is fine). You can pick one up at your major retailer for about $12.99. This will speed up the mixing process. It is not required but makes things a lot easier and faster!

Soap Making Kit IngredientsOur soap making kits include all the necessary pre-measured ingredients. These ingredients include: Our base oil blend (sunflower oil, safflower oil, coconut oil, and palm oil), Lye, herbs/botanical additive, and essential oil. The image to the right displays all the ingredients for our Peppermint Soap Making Kit. Other kits will include different herb/botanical additive and essential oil depending on which kit is chosen.

Prepare the Oils

Mix Until Trace
