How to Make Sea-Salt Soap

Things You'll Need

  • 2 lbs. goat’s milk melt-and-pour soap base
  • Microwave-safe bowl
  • Silicone spatula
  • Spray bottle of rubbing alcohol
  • Coarse sea salt
  • 1 tbsp. fine sea salt
  • 1 tbsp. beeswax
  • Blue soap-safe dye
  • Yellow soap-safe dye
  • Ocean Mist-scented fragrance oil
  • 2-lb. soap mold

Sea salt has excellent exfoliating properties and is used in body scrubs and other bath products. Sea-salt soap is easy to make, requiring only your favorite melt-and-pour base and ingredients from your local grocer. Dyes and fragrances enhance the presentation; you can find these items at craft stores and online retailers, like Brambleberry.

Cut your soap base into small, even chunks and put them in the microwave-safe bowl. The smaller and more even the chunks, the more evenly they will melt. Cover the bowl with plastic wrap and microwave the soap until melted. Heat the soap in one-minute increments, stirring often.

Mix the beeswax into the soap until it melts. Mix the soap gently, to avoid forming bubbles. If bubbles do form, spray the surface with rubbing alcohol.

Mix one-half ounce of Ocean Mist fragrance to the melted soap. Spray the surface of the soap with alcohol if bubbles form.

Mix 15 drops of blue dye and five drops of yellow dye into the soap. The soap should be an aquamarine color; you may need to adjust the dye ratio to get the desired color. Stir the soap and spray the surface with alcohol, if needed.

Add one-half cup coarse sea salt and one tbsp. fine sea salt to the soap and stir lightly. Do not over-stir; you want the coarse salt to remain intact. Spray the surface of the soap if needed.

Sprinkle a layer of coarse salt into the bottom of the soap mold. Then pour the soap on top of the salt. Put the mold in a safe place and allow it to cool and harden. (It should take about 24 hours.)

Remove the finished bar from the mold and trim any excess with a small knife. Store the soap in plastic wrap or wax paper. To use the soap, cut the amount you need with a chef’s knife or soap cutter.


  • This soap is scented with Ocean Mist fragrance, in keeping with an aquatic theme, but any fragrance will do.


  • Melt-and-pour soap can get very hot, so handle with care. Only use soap-safe dyes when coloring soap. Other dyes may irritate or stain the skin.
