Castile Soap – Olive Oil Recipe

From Castile, or Castilia, a province in Spain, from which it originally came.

A kind of fine, hard, white or mottled soap, made with olive oil and soda. Although this soap is slow to lather, a little work yields an abundance of rich, creamy suds mild enough for the most sensitive skin. Castile soap is so gentle, it’s often used as baby’s first soap.

Ingredients:

Makes 2 lbs. Very Easy.  This is true Castile soap.

  • 24 ozs of Pure 100% Olive Oil
  • 1 oz of beeswax pearls (gives this bar a silky texture)
  • 4 ozs of lye (sodium hydroxide)
  • 10 ozs of distilled water

Follow the basic cold process soap making instructions. Soap temperature 100-120°, a bit hotter should be fine since this is a small batch and will loose heat quickly. Cure for 6 weeks for best results.

Melt the beeswax in the olive oil until temperatures reach approximately 120°.  Add the lye to the water stirring well (follow basic cold process instructions) and add to the oil/beeswax mixture when it cools to 120°.  Stir until trace and pour into mold.

Optional additional additives: Ground dried chamomile 1/4 cup or less and chamomile fragrance oil (2 ozs.) added at trace.
