Project Overview

This easy soap recipe is a great introduction to melt & pour soap. If you’ve never made soap before, try this recipe to see for yourself how easy it is with a melt & pour soap base!

We’ll start by weighing and cutting the soap base, then melting it in the microwave. Green mica and Irish Spring (type) fragrance is added to create that iconic Irish Spring look. Finally, the melted soap is poured into a classic oval soap mold and left to harden. These bars of soap will fit perfectly into any of our rectangular soap boxes for professional-looking packaging.

  4. In a clean 1 oz measuring beaker, weigh out 0.5 oz of fragrance oil. Add the fragrance to the melted soap and stir.
  5. Spritz the soap mold with rubbing alcohol, then pour the melted soap into each cavity.
  6. Immediately after pouring, spritz the top of the soap bars with rubbing alcohol to remove any bubbles.
  7. Let the soap set up for 2 hours (or until hard), then carefully remove the soap from the mold.
  8. Assemble the soap boxes and gently slide a bar of soap into each box. Label accordingly if you plan on selling the soaps.

Note: This recipe calls for a 2.5% fragrance load. If you wish to make a stronger-smelling soap, you can add up to 1 oz of fragrance to achieve a 5% fragrance load.
