What is rebatching soap?
If you've come this far in your soap-making journey, you may already know what rebatching soap means. In a nutshell, rebatching involves the following:
- Taking a cold-processed (100% homemade) soap or pre-made soap base
- Shredding or cutting it up
- Melting it down to re-create it into something new.
There are some who would have you believe that this technique should only be used to save scraps from the cold-process soap making process or to add light fragrances or additives that won't stand up to the lye used to make soap from scratch. While those are both true and valid reasons, I think there is a beauty to rebatching soap, as it creates a very rustic, country-looking soap. Let's make it!
What You'll Need
- Pre-Made Rebatch Base. I use Stephenson's Rebatch base, which can be purchased from Bulk Apothecary or from the Chemistry Store. You could also buy a block of cold processed soap from someone that makes it.
- Hand Shredder/Salad Shooter.
- Crockpot/Double Broiler. For this guide, I will be using a crockpot.
- Stirrer. This can be something like a spatula or long-handled spoon.
- Soap Mold. I prefer the loaf-style soap molds, but you could also use a tray mold. Whatever you choose, keep in mind that you need to be able to get your soap into the mold quickly. Because rebatched soap doesn't become a complete liquid, it's hard to pour into a very detailed design. Other ideas for molds are muffin pans or square brownie pans. You get the idea.
- Additives. This could be the fragrance oil (FO) or essential oil (EO) of your choice. You can also add botanicals, oils, or butters (such as shea, cocoa, or mango).
- 2 lbs Stephenson's Rebatch Base
- 8 oz distilled water
- 1 oz French Vanilla and Amber fragrance oil
- 1 tbsp cocoa powder
1. Cut up the Base
2. Shred the Base
3. Add the Shredded Base to the Crockpot
5. Continue Waiting
6. Add Fragrance and Stir
7. Add Cocoa Powder for Color
8. Scoop and Pour the Base Into the Mold
9. Wait for It to Set
10. Remove It From the Mold
11. Cut the Soap
Enjoy the Soap!
You could use your soap immediately after creating it, but you may find it a little soft (almost spongy with a gentle squeeze). This is because there is still extra moisture (water) in the bar. If you use it like this, the bar will not last as long. For a harder, longer-lasting bar, place your soaps on a drying rack and allow it to dry. The longer you wait, the harder they will be. You'll know they're ready when they will feel as hard as a store-bought soap!
Now you know the basic steps that can be applied to making any rebatch recipe! Thank you for reading. I hope you found this informative. If you have any questions, please feel free to ask me.

I loved your tutorial on rebatch. Very easy to follow and loved your photos too. I have a bunch of Olay soap slivers that I will be rebatching. May throw in some other soaps such as castile. I also plan on using beer instead of water. In another post, the lady said that the beer gave it lathering properties, which I want in my medium hard water. Thanx again!
