Like an idyllic sky, this homemade soap is all softness and light!

Have you been dreaming of a cold process soap recipe that’s as soft as a cloud, looks like the sky, and is so light it floats on water? Dream no longer: Coop Coco has created it! After many hours of research and reverie, we’ve finally achieved a soap as inspiring as the heavens. Come join us On Cloud Nine with our new DIY soap!

Rich in solid butters whipped up like a fine Chantilly cream, this soap is softness incarnate—and it’s as good for your skin as it looks. Like a dessert, this homemade soap is made with an electric mixer, which fluffs up the mixture by whipping air into it. That’s what gives this creation its beautiful and unusual buoyancy, leaving it light enough to drift dreamily on the water’s surface.  

Just one word of warning: as with any soap recipe, it’s important not to have your head in the clouds while making it. But you can drift off into daydreams when you’re On Cloud Nine in the tub!

How to make floating soap

Before you begin

  • The advantage of this technique is that there is no need to worry about trace, simply because there isn’t one.
  • What makes this recipe special is that you have to work with both the sodium hydroxide solution and the oil and butter mixture at low temperatures. The oils and butters must have a very specific texture when mixed in order to achieve the whipped effect. If the sodium hydroxide and sodium lactate solution is too hot, it will melt the butters and oils and you won’t be able to achieve the desired texture.
  • You’ll notice that there is no mention of superfatting in the ingredients list or instructions. This is simply because we decided to superfat this soap recipe by reducing the volume of sodium hydroxide. It’s another interesting way to make cold process soap!

Good to know!

  • This soap takes longer to harden (approximately 48 hours) than a traditional cold process soap recipe.
  • Sodium lactate is used so that you can unmold your creation sooner, and to prevent crumbling.
  • To cut your floating soap, use a guitar string, knife, or soap-cutter. For the latter two, remember to dip the utensil in hot water between each cut.

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. Place the Pyrex cup or HDPE pot into the ice water bath. Leave to cool until it reaches 15–20 °C.
  5. In the meantime, weigh the cocoa and shea butters and the coconut oil. Melt on the double boiler.
  6. Weigh the grapeseed and castor oils in a small bowl. Set aside.
  7. Weigh the blue mica in a ramekin. Add a bit of the oil from step 6 and disperse the pigment.
  8. Allow the butters and coconut oil to cool in the fridge or freezer until the mixture has a balm-like texture.
  9. When this texture is reached, beat with the electric mixer until it resembles the texture of whipped cream.
  10. Gradually add the grapeseed and castor oils while mixing with the electric mixer. Continue to mix until the batter is homogeneous.cold process soap recipe
  11. Gradually add the solution of sodium hydroxide and sodium lactate while mixing with the electric mixer.
  12. Pour in the essential oil and mix well, still using the electric mixer.
  13. Continue to mix until the batter reaches the texture of whipped egg whites.DIY whipped soap
  14. Pour half of the soap batter into the mold a bit at a time. Tap the bottom of the mold on your work surface between each pour.
  15. Add the mica to the rest of the soap. Mix with the spatula, then again with the electric mixer. homemade floating soap
  16. Pour the coloured soap batter into the mold a bit at a time. Tap the bottom of the mold on your work surface between each pour. When all the coloured soap is poured in, swirl a spoon in the batter to create the sky pattern.whipped soap recipe
  17. Decorate the top of the soap using the tip of the thermometer.
  18. After 24 to 48 hours, place the soap in the freezer for an hour (this helps prevent crumbling). Unmold, then wait 30 minutes before cutting. Be sure to follow the advice given in the “Good to know” section.
  19. Leave to cure in a cool, dry place for four to six weeks.

    Hello guys!! This recipe is amazing but i’m concerned about the consistency, is it creamy or like a solid soap?

    This sounds pretty exciting! This is the first whipped soap recipe I have found that doesn’t contain palm oil or tallow or lard. Thank you so much. I was just wondering, is it possible and would my soap turn out as great, if I substituted grapeseed oil with some other soft oil say extra virgin olive oil? What would you suggest? Thank you in advance.

      If you change one of the oil, you have to use a calculator, since the proportion of water and caustic soda will most likely change. Also, please note that we never tried to whip soap with a different recipe, we can’t assure you the final result.
      Have a great day!

    Hi, I have tried this.
    I poured it into a mold all excited that it would beautiful creamy goodness. I wanted it to maintain a creamy matte finish so I put it in the freezer overnight. I went to cut it and the soap crumbled and kind of fell apart. The appearance in the cut was rough looking and not smooth. When I went to touch it, the inside even seemed damp and a bit moist to the touch.:( I wish I could post a photo here. Wondering what could have gone wrong. I did not have sodium lactate but read that a bit of table salt will work, I added only 1 tsp even a bit less than that. Does it make a difference of the temperature of the lye water? I made that first and let it sit until I was ready to add it to the fluffy mixture. It really was like clouds and when I dispersed the lye water even then it did not trace quickly but was a beautiful creamy texture. Traced very slowly. I really was excited that it would be awesome. :( I tried a zap test but it just was sour lol then I used one of the cuts and washed my hands with it (almost no bubbles at all, and dried out my hand something awful) but no red irritation to indicate that there was too much lye. I want to try again to make it but would love some tips of where I may have gone wrong. Can you make soap out of any body butter mix? Thank you kindly in advance!!!

      Hello Susan,
      Sodium lactate is used to facilitate the unmolding and to prevent the soap from crumbling. Replacing it with salt doesn’t seem like the right thing to do, we really recommend using sodium lactate.
      Did you follow the recipe? We do not mention a trace in this recipe (as we explain in the “Before you begin” section). This soap recipe is a very special one, especially compared to a classic cold soap recipe. It is really important to follow all the steps and the information given (ingredients, temperatures, etc.) to be able to make this soap.
      Since we weren’t by your side during the making process, it’s difficult for us to know exactly what the problem is, but based on what you’re describing we think the concern is that the recipe wasn’t followed.
      Also note that we strongly advise against using fresh soap (this is not good for the skin, as you saw it) or testing it with the tongue. It’s not safe. We recommend using pH paper to find out if your soap is usable or not.
      If you want a soap that stay “whipped and soap”, you can try this recipe (which is not a cold process soap) :
      Have a nice day!
