Liquid Soap

Making liquid soap from a bar is a simple life hack that takes substantially less time and uses fewer tools and ingredients than you think.

You can stretch a single bar of soap into a few bottles of liquid suds using a quick DIY process. Making liquid soap from a bar is a simple life hack that takes substantially less time and whilst ‘liquid soaps’ may be harder to find in the supermarkets there are plenty of bar soaps in stores. All it takes is around 10 minutes of prep time, a few supplies, and you’re ready to make your first batch.

Thank you to one of my Thermomix customers for sending me this recipe from the wonderful Petra of The Road to Loving my Thermomix.


  • 120g soap bar, cubed
  • 1200g of water


  1. Blitz soap bar on speed 5, slowly working up to speed 8 until fine.
  2. Melt at 80 degrees, speed 2 for 2 minutes or until melted. Some people find they need to increase the temp and speed slightly. If its not melting increase to 90 degrees, speed 3. Add a little of the water to help the process.
  3. Continue to mix at 80 degrees, speed 2 whilst pouring water slowly in to the bowl through the hole in the lid.
  4. Continue to mix for 2 mins or until nice and smooth.
  5. It will look like milky water. Don’t panic like I did. I almost threw it out thinking I put too much water in.
  6. Pour into a big bowl.
  7. Now leave it for the day.
  8. As time goes on it thickens. Just keep giving it a stir every hour or so. Its not essential to stir hourly, just regularly.
  9. I bottled mine after approximately 12 hours. Keep any extra in a bottle in a cool dark spot until needed.
  10. If you find it’s too thick just pop it back into the TM Bowl and blitz on speed 8 for 30-60 secs. That will smooth it out again.
  11. Thin with a little water if needed

However, the recipes here are things I do with my own Thermomix.  I also have multiple Thermomixes and TM bowls, so I can safely use separate bowls for making these without any cross-contamination. I also clean the bowls thoroughly with soap, then vinegar, and finally run it through the dishwasher to ensure that it is thoroughly clean before making a food recipe in my bowl. If in any doubt, don’t make them.
