Foaming Bath Butter (Whipped Soap Base) Recipe

There is a particular kind of pleasure in a lather made well — one that rises up soft and cloud-like in your palm, smells exactly the way you'd hoped, and turns an ordinary shower into something closer to a spa. This is that lather. A whipped blend of gentle cleansers and skin-loving butters comes together into something light enough to float, finished with whatever scent (and shimmer, should you like it) feels most like you. No harsh sulfates. No stripped, tight-feeling skin afterward. Just a rich, foamy cloud of a cleanser, and the quiet satisfaction of having made it yourself.

Instructions

  • Prepare your workspace. Weigh out every ingredient into its proper phase — water phase, oil phase, cool-down phase — before you begin heating anything at all.
  • Combine the water phase. Combine the distilled water, vegetable glycerin, propylene glycol, tetrasodium EDTA, and SCI in a heat-safe container.
  • Combine the water phase. Combine the distilled water, vegetable glycerin, propylene glycol, tetrasodium EDTA, and SCI in a heat-safe container.
  • Begin whipping. Pour the heated water phase into a tall mixing container and give it a light pass with your hand mixer. Some bubbling here is completely normal.

  • Combine. Pour the oil phase into the water phase and mix well. The bubbles will get a little wild, but they shouldn't escape the container. At this stage, the mixture is still quite runny.
  • Add the cool-down phase. Once the mixture has dropped below 110°F (43°C), mix in the Liquid Germall Plus (and fragrance oil, if using) until fully incorporated.
  • Let it cool. Allow the base to cool, stirring occasionally. You'll notice it beginning to thicken as it does.
  • Whip it. Once fully cooled, give it a good whip with your hand mixer until it reaches a light, fluffy, cloud-like texture.
  • Jar it up and let it set. Transfer to your sanitized container. Label with the date made.
