Orange Lemon Castile Soap

IMG_0865

You can tell the soap hasn’t completely cured yet. The inner part of the soap is still quite moist.

This is my first Castile soap. Castile = pure olive oil soap. I’ve heard that it’s a luxurious and gentle bar of soap, after it cures for 6-8 months. Castile soap recipes are different than regular CP soap recipes. First, you must apply a water discount (Yikes, that means the concentration of lye is much higher – in the neighborhood of 40%). Second, you mix the EO with your base oil before adding lye. Third, the cure time is 3-4 times longer.

This recipe is for five pounds of soap.

Ingredients:

*All measurements are weight measurements, not liquid measurements.

  • 56 oz Olive Oil
  • 17 oz water
  • 7.4 oz lye (Sodium Hydroxide)
  • 1 oz Lemon EO
  • 1.5 oz Orange EO

 

Base Oil Composition:

  • 100% Olive Oil

Directions:

Make sure you follow all the general safety precautions for making soap before you start.

  1. In a heat-safe container, add lye to your water, stir, set aside to cool. Be very careful not to spill, as this is a highly concentrated solution of lye. Keep some white vinegar nearby for an emergency neutralization.
  2. When the lye solution is close to 110F, set up a double boiler. Gently heat the olive oil to about 100F.
  3. Combine the EO and olive oil. Carefully pour the lye water into the oils. Gently stir with a heat safe rod.
  4. Pulse the stick blender in the mixture a few times, and then gently blend until you reach trace.
  5. Pour in the mold, and wait 1-2 days before cutting.
  6. Cure for 6-8 months.
