Equipment

Ingredients

  • 11 ounces coconut oil
  • 9 ounces olive oil
  • 9 ounces palm oil
  • 2 ounces sweet almond oil
  • 4 ounces castor oil
  • 4 ounces avocado oil
  • 2 ounces mango butter
  • 5.83 ounces lye
  • 10-15 ounces water
  • 3 tablespoons fragrance oil for a strong scent, vary this to your preferences
  • 2 teaspoons sodium lactate optional, for a harder bar
  • colorant or mica optional

Instructions

  • Using a digital scale, measure out the lye and water in separate glass containers.  Combine them by adding the lye to the water.  (Remember: snow floats on the lake.). Stir until the lye dissolves.  The temperature will shoot up.  Place this in a safe place to cool.
  • While the lye solution is cooling, measure out the oils and butters and combine them in a large stainless pot.  Melt them over low heat and heat them up to 130-140 degrees.  Set them aside to cool.
  • After 2 hours, check the temperature of both solutions.  They should be around 110 degrees.  (A range of 100-120 is fine.). If not, allow them to cool longer.
  • Prepare your mold and measure out any fragrance or color you will be adding.  (For best blending of colors, mix some color into a few drops of melted oils.). If using sodium lactate, add it to the lye water at this time.
  • Pour the water and lye solution into the pot with the melted oils.  Blend with a stick blender until thin trace is reached.  The soap batter will noticeable thicken and a trail of soap will sit on top of the liquid rather than immediately sinking in.  (This will take about 1 minute.). Add the color and fragrance and stir by hand.
  • Immediately pour the soap batter into the mold.  Place in a turned off oven or wrap with blankets to insulate the soap.
  • After 24 hours of curing, unmold and cut into bars.  The bars may seem slightly soft but will harden considerably during the curing process. Allow to cure at least 3 weeks in a well-ventilated place.
