pouring castile soap into a glass container

Castile liquid soap recipe

1/2 cup castile soap
1/2 cup boiled and cooled water
1 teaspoon vitamin e oil
15 drops tea tree essential oil
10-15 drops of your chosen essential oil for fragrance (I like lavender or lemon)

Method one directions

  1. Mix your essential oils into your vitamin e oil. This will mix it in and allow the essential oils to blend into the final hand soap.
  2. Mix the vitamin e and essential oils into the castile soap. This is vital to help everything blend smoothly. If you are storing this recipe for more than a few short weeks stop at this point and add the water when you are ready to use your liquid hand soap.
  3. When ready to add the water you want to sterilize the water before you begin. Bring the water to a rolling boil then allow cool, this will prevent melting your hand soap container and pump. Add in your concentrated liquid hand soap mixing well until your soap has blended.
  4. Pour it into a hand soap container.
  5. Give this hand soap a shake if you notice and separation and make a point to use this up quickly. If your hand soap has time to go bad you may not be washing your hands enough.
  6. If you leave and your soap is left for an extended period of time, toss it out and make a fresh batch.
