• 100 g of sodium coco sulfate (SCS)
• 60 g of sodium cocoyl isethionate (SCI)
• 20 g of water
• 8 g of citric acid
• 12 g of washing soda (sodium carbonate)
• 250 ml wide-mouth Mason jar (or any shallow jar)
• dish scrubber, dish brush or loofah

WARNING: SCS and SCI are irritating to the respiratory tract and mucous membranes in powder form. Handle them gently to avoid making the powder “fly”. For extra protection, wear a dust mask (N95). Once the recipe has dried, the dish soap cake is completely safe. No need to wash dishes in your chemist's gear, come on! Hahaha. ;)

1. Measure the SCS and SCI, and pour them into a small saucepan.

2. Add the water and place the saucepan on the burner over very low heat (minimum).

3. Gently stir with a spoon, crushing the crystals, until you get a soft, pliable paste. As they heat up, the ingredients will be easier to mix. Note that surfactants soften but don't completely dissolve in water.

4. Remove the saucepan from the heat.

5. Add the citric acid and washing soda. Mix well until smooth.

6. Using a spoon, fill the Mason jar.

7. Press down well, again with the spoon or your hands (careful if the mixture is still very hot) to pack the cake into a compact block.

8. Let dry and harden for a few hours. You can press it a few times with your hands to compact it as much as possible.

Option 1

If you're the type to give your dishes a shower, wet your brush or sponge (we love the loofah for this!) and rub the surface of your cake until your sponge or brush is soaked with lather. Then wet your dishes and rub your brush or sponge on them to clean them.

Option 2

If you're more the type to give your dishes a bath, when you fill your sink, let a thin stream of water run over your cake for a few seconds. The water will activate the product and make it foam. Result? Lovely soapy water. Wash dishes as usual!

Happy dishwashing!
