Making Rebatched Marble soap with scraps of soap

Ingredients

150 g of water

600 g Soap scraps or CP (Cold Processed) soap made with used oil

400 g MP (Melt and Pour) soap base

Essential oils

Slow cooker

Mold

1. Cut the MP soap base into pieces as small as possible.

2. Cut the CP soap base into medium pieces to make texture in the design of the soap.

3. Put the water, MP soap, and CP soap in the slow cooker.

4. Heat it for 3 hours at high heat.

5. After the 3 hours when the MP soap is completely melted and the CP soap is still in small chunks, mix essential oils into this mixture.

6. Pour the mixture into a silicon mold.

7. If there are extra soap pieces, put them on top of the soap in the mold for decoration.

8. After 2 days when the soap is hard, cut it into bars.

9. Dry these soaps even more for about a month before use.

Why should we recycle used oil anyway?

Proper oil waste disposal is crucial. It is important to save used cooking oil instead of pouring it down the drain. It could potentially clog drains or seriously inhibit plant growth if it gets into nature. So, we make biodegradable soap out of the oil, so it is not wasted and when it does get into nature, the soap does not affect anything.
