Melt and Pour Soap instructions

One of my children’s teachers asked for my recipes for melt-and-pour soap–I wrote them up and figured I’d post them here too, though there are plenty of places online which have similar versions…

Melt-and-Pour Soap Instructions:


  • Melt and pour soap base (available at craft stores like Michaels or JoAnn’s, or online.  Usually available in 1 or 2 pound blocks.) I like Goat Milk soap bases, they leave the skin very soft…
  • Pure Essential Oils for fragrance. (These are much better than the “fragrance oils” you would buy in the soap department.) Available in healthy-food stores or online. They can be expensive, but some of the best soap ones, like lavender, sweet orange, peppermint, and/or rose geranium, are not too expensive. (Genuine Rose is really expensive; rose geranium is nice but more affordable!) 
  • Optional: soap color dyes, also available wherever you buy the soap.  These make it pretty but don’t add anything to the quality of the soap.
  • Soap molds: you can get “real” molds from the craft store or you can use loaf pans or little round Tupperware containers, or whatever you have.



    1. Cut up soap into about 1 inch pieces and place in a heat safe glass container (I use Pyrex measuring cups) in a pan of gently simmering water. Allow to melt, stirring often.
    2. Add color, a few drops at a time until you like your result.
    3. Add fragrance, also a few drops at a time, and stir well.  Generally about 20 drops per ounce of soap is the most you’d want to use; some oils are stronger than others. (Lavender you can use a lot of; mint and rose geranium, take it easy!)  Stir very very well
    4. Pour into your molds and let sit until hard. (Note: If you want your soap to harden quickly, put the molds into a cold room or refrigerator and pour the hot soap into them there.  It’s very hard to move the molds after you pour without getting wrinkly soap!)
    5. Unmold; if you used a loaf pan, you can then slice the soap into bar-sized pieces.



  • You can make two different color/fragrance combinations and pour them together into the mold; do not stir. They will swirl together. (For a little more swirl, run a knife gently through after pouring.)
  • For “speckled” soap—make a small amount of soap (your secondary color) and unmold, then cut it into pieces about ¼ inch in diameter. Chill till very cold and sprinkle into soap mold. Melt a larger amount of soap in your primary color/scent and pour around the little pieces.
  • For “rainbow” soap—use a loaf pan. (This takes a long time!) Starting with pink/red, make a single batch of soap and pour about ¼ inch deep in your mold; let chill to set thoroughly. Repeat with orange, then yellow, then green, then blue, then purple. Pour each layer on top of the previous layer; when all are hardened, slice into bars.


About Essential Oils:

  • Different oils have different qualities and will affect your skin differently:
    • Lavender is gentle and soothing and fine for children’s skin. (Chamomile too!)
    • Citrus oils are good for oily skin, but they can irritate—orange is the safest citrus oil.
    • Rose geranium is good for mature skin
    • Rosemary is good for acne-prone skin
    • Mint and eucalyptus are invigorating and good for headaches and tired muscles
    • Avoid spice oils! Cinnamon, clove, etc. smell lovely but can cause irritation.
