How To Make Lotion Soap

When you make melt and pour soap, you can add all kinds of skin loving, moisturizing ingredients to give your bars additional benefits. One of the things you can add to your soap is lotion. Both skin lotions and melt and pour soap base are made from glycerin, so they blend well and make a great batch of soap.

When choosing the lotion you want to add to your soap, unscented white lotion is the best way to go. You can add your own scent and color during the soap making process.

To make lotion soap, you'll need:

  • 1 pound opaque (white) melt and pour soap base
  • 1/4 to 1/3 cup skin lotion
  • Soap dye
  • Fragrance oil or essential oil
  • Rubbing alcohol in a spray bottle
  • Large metal pot
  • Large glass or Pyrex measuring cup
  • Metal spoons
  • Soap molds

Making lotion soap:

  1. Chop the melt and pour soap base into small chunks, and place the chunks in the measuring cup.
  2. Fill the pot about halfway full with water; place on the stove and bring water to a low simmer. Place the measuring cup containing the soap chunks in the water.
  3. Allow the soap to melt, stirring occasionally and gently. Too much or too vigorous stirring will cause air bubbles to form, and you want to avoid these.
  4. When the soap base is almost completely melted, remove the measuring cup from the pot and continue to stir gently until the base is smooth and all lumps have dissolved. Add the lotion and stir to combine.
  5. Add your soap dye, a little bit at a time, until you get your desired shade. Add about half a teaspoon of fragrance oil; stir well and add more if desired.
  6. Prime the molds by spraying a very thin layer of rubbing alcohol inside them. When your soap base has cooled somewhat but is still in a liquid state, pour it into the molds, filling them completely. Spray the tops lightly with rubbing alcohol to prevent air bubbles from forming.
  7. Set your full molds aside for several hours or overnight to harden. When ready, turn the molds over and pop out your lotion bars. Buff any rough edges with the back of a hot metal spoon, or scrape with a vegetable peeler. Your soap is now ready to use!

To store your bars, wrap them tightly with plastic wrap and store in a cool, dry place.

Lotion bars will turn out softer than a regular bar of soap, but they still lather well and leave your skin feeling nice and soft. After use, let your soap air dry in a soap dish to keep it from turning mushy.
