Nevertheless, if you’ve never tried making soap before, we don’t recommend that you start with this recipe! To succeed with it, you must have already mastered trace. What’s more, this decorative soap requires a lot of patience… But we promise, it’s worth it!

With this DIY soap, you’ll finally discover what’s hiding at the end of the rainbow!

How to make homemade soap?

Before you begin

  • Sodium lactate will solidify the soap more quickly, but it also accelerates trace. We use it here so that the soap can be unmolded more quickly (in 24 to 48 hours).
  • In this cold process soap recipe, we will be working with a light trace only, in order to create nice straight, even layers. It is thus important to use the immersion blender in a moderate way so as not to accelerate the reaction.

Ingredientshow to make soap

Oil mixture/blend

Sodium hydroxide solution


Essential oil mixture

Colourants for each coloured layer


Steps to follow

  1. Prepare and disinfect your equipment and workspace
  2. Take the necessary precautions for handling sodium hydroxide safely
  3. Prepare the sodium hydroxide solution: measure the water and sodium hydroxide separately; pour the sodium hydroxide into the water, contained in a Pyrex measuring cup or HDPE pot; mix together and leave to cool.
  4. In the first ramekin, weigh the essential oils with a pipette and mix together.cold process soap recipe
  5. In the six other ramekins, weigh the colourants using the spoons. Be sure to use a different spoon for each colourant or to clean your spoon well between measuring each colourant so as not to combine the pigments.making soap
  6. Weigh the mango butter for the superfatting in a small bowl and melt on the double boiler.
  7. Weigh the coconut oil and stearic acid in the large stainless steel bowl and melt on the double boiler. Once melted, remove from heat and add the oils (olive, castor, sweet almond, and sunflower).
  8. In each measuring funnel pitcher, disperse each colourant into 250 g of the oil mixture obtained in step 6.
  9. Mix the colourants into the oils well with the silicone spatula. Next, to avoid any clumps forming, disperse the colourants with the immersion blender. Remember to clean the blender between each colour so as not to mix them.
  10. In the second Pyrex measuring cup or HDPE pot, weigh 110 g of the sodium hydroxide solution for the first colour (purple).
  11. When the oil mixture and sodium hydroxide solution have both cooled to a temperature of 26–29°C, add the 110 g of the sodium hydroxide solution to the 250 g of purple oil mixture. Stir with the spatula to combine.homemade soap recipe
  12. When the sodium hydroxide and oil mixture is homogeneous, mix with the immersion blender in little 5-to-10-second bursts until it reaches light trace. You must be patient for this step!
  13. When the soap batter has reached light trace, add 7 g (8.5 ml) of the essential oil mixture and 7 g of the superfatting oil to the batter with the pipette. Mix well with the silicone spatula. When the consistency of the mixture is homogeneous, mix again with the immersion blender in 5-to-10-second bursts while regularly checking the trace.DIY soap
  14. When the trace is light and the consistency is still liquid, it’s time to pour the soap batter into the mold. This way, each layer will be perfectly straight and you’ll achieve the intended pattern.
  15. Wait until the layer has hardened. To check its hardness, lightly touch the soap later with your finger, while still wearing your protective gloves, of course! The soap should not stick to your finger.
  16. Once the layer has hardened, repeat steps 9–14 for each colour. For a successful rainbow pattern, the next layers should be poured in the following order: blue, green, yellow, orange, and lastly red.
  17. Remember to clean the immersion blender between each colour so as not to mix them.
  18. Cover the soap for 24–48 hours.
  19. Wear gloves to unmold the soap. Cut and leave soaps in a cool, dry place for 4–6 weeks to cure. Now you can enjoy your homemade soap!
