Rebatching Soap




Introduction: Rebatching Soap

I made this soap yesterday. I made it cold process, so it is now soap, but it is still very moist. If I wanted to use it as is I would cut it into bars and wait 3 or 4 week for them to dry out. However I made this batch to rebatch.

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Unmold the Soap

Gotta love silicone, unmolding is so easy.

Step 2: Cut the Soap Up

I cut the soap into strips about 1" wide.

Step 3: Grind/grate/chop Soap

I love the meat grinder for this, but the object here is to reduce the large pieces of soap into smaller pieces. As I stated in the introduction the soap is still quite moist therefore soft. A cheese grater works, so would a chopper of some type, you could even cut it up into small pieces.

Step 4: Measure Your Batch

I did a 1 pound (454g) batch, and bagged the rest of the soap for another batch.The important thing if you are saving some for later is to preserve the moisture content, hence the sealed bag.

Step 5: Starting the Heating

I used 3/4 of a cup of warm goat's milk and added the pound of soap to it. You could use water here, but I wanted to make goat's milk soap. 1/2 a cup is a good place to start, add more if you need to. To much and it will take longer to dry.

Step 6: Heat and Mix

If you have a temperature programmable crock pot, set it to around the boiling point (+/- 5 degrees) or put it in the oven at the same temp. A double boiler works too. Because there is already a high moisture content in the soap it will break down quite fast.

Step 7: Ready for Any Additions

At this point I added 1/2 tbsp of lavender essential oil. Depending on what you want from the final bars will determine what you add.I have added ground oatmeal, ground corn meal, ground coffee, different essential oils, spices, algae, and the list goes on.

Step 8: Re Mold the Soap

The final step here is to pour it into a mold. In a day or 2 I will unmold it and cut it up and leave it dry for several weeks, then I will have lavender goat's milk soap.

    Ray, I like this instructable. You did a nice job on it. Have you thought of making an instructable for making soap. You mentioned that this rebatch came from some soap you'd made. I would like to learn to make soap and it looks like you're the person I want to learn from.

    An easier way to save small slivers of soap is to save the plastic net bags that garlic or small onions come in. Collect the slivers and place them in the bag. Tie the bag off. This is not beautiful but excellent for kids and adults who need the bit of help removing heavy dirt and grease the plastic netting provides.

    I know you can rebatch cp soap, but does this method work with any store bought soap? Like Camay or dialnor like oil play?or is that not possible?

    Is it possible to use the same process to "recycle" left over soap slivers and hotel soaps?

    Yes you certainly could. Grate them as fine as you can, they will melt better that way.
