Can you believe it’s re-batch? A tutorial



it is not often that I have a bad batch of soap. In fact I have only had 4 in 5 years. 3 Of them have been in the last 2 months. So with these “bad” batches I decided to make rebatch. I love the consistency of this batch and the unmelted flecks in it.

This is what the soap looked like before I made it into re-batch. Really pretty! But alas when I cut it is was crumbly and hard, a sure sign that something had gone wrong. So it got grated and remade.


  • Grated Scraps:           1177.5    gr   
  • Water:                         28.6    gr   
  • BaseOil:    Castor       18.2    gr   
  • FO:    FO of choice     37.0    ml  


  • Prepare your mould ahead of time.
  • Take the grated soap and place it in a microwave jug or heavy duty plastic bucket. It’s going to get very hot.
  • Take all your wet ingredients, except the Fragrance oil and pour that over the grated soap.
  • Place the jug/bucket in the microwave and microwave the mixture on 50% strength for 5 minutes.
  • Take it out and see if it has started to melt. If not do another 2 minutes on 50%. This is not an exact science and all microwaves are different so you will have to eyeball it.
  • Place back in the microwave on high for 1 minute. You should have a melted mass of soap. If it is not all melted then keep going in 30 second bursts until it is all melted. You are looking for Apple sauce like mixture. Unfortunately no picture is available.
  • You may need to add more water if it is really thick. Don’t add too much though as your soap will be very soft and you will have to wait for the water to evaporate from the soap.
  • Once the mixture has cooled slightly add your fragrance oil and mix really well. Pour into your mould and leave for a few hours or over night.
  • Once it has cooled down and set  you can cut the soap and if it is hard enough

  1. Thank you for sharing about the whole process! I think that your rebatch look just as gorgeous as your original idea. :)

  2. Thanks for the tutorial. Rebatch looks amazing. Happy to see you survived grating over a kilo of soap.

  3. Great Save!

    Do you have any idea why your rate of failed batches kicked up? Using a new technique or a new ingredient, fragrance or source?

  4. I never knew you could make rebatch in the microwave!! I sure gonna try this!
    How long after making your CP it's ready to be rebatched?
