A very simple, very effective handmade soap recipe for the absolute beginner in cold process soaps.

When you are first starting out making cold process soaps it can be a little daunting seeing the huge lists of horribly expensive ingredients you need.

This recipe only uses three base oils all of which are easily available and relatively inexpensive. The soap it produces is hard and lost lasting with a lovely fluffy lather.

You Will Need

  • Digital thermometer.
  • Large stainless steel saucepan
  • Digital scales measuring in grams
  • Hand blender
  • Silicon bread loaf mould.
  • Rubber gloves and goggles.

For The Soap

  • 369g Olive Oil
  • 85g Coconut oil
  • 14g Castor Oil
  • 142g Pure water
  • 62g Caustic soda

To Make The Soap

Put the rubber gloves and goggles on. Pour the caustic soda slowly in to the water stirring with a metal spoon. The mixture will heat up and may boil as the soda reacts with the water. Continue stirring the solution until it becomes transparent. Put to one side to cool down. This solution is called lye.

Weigh the oils in to the large sauce pan and heat gently until the coconut oil has melted.

Use the digital thermometer to measure the temperatures of both the oils and the lye. When both are roughly 90 F (32 C) and within 10 degrees of each other then they are ready to be mixed.

Pour the lye slowly into the pan with the oils using the hand blender, set on the lowest speed, to mix the two. The mixture will quickly become cloudy and will thicken in a matter of minutes. Keep mixing with the hand blender until the soap has thickened and become a pale yellow colour, similar in consistency to very thick custard. This stage in known as trace and if you were going to be adding fragrances or essential oils then this is the time to do it.

Slowly pour the soap into the loaf mould. Set this to one side and leave for four days, during this time the soap will harden. Pop the soap out of the mould and leave for 48 hours. Cut the soap into slices and leave in a cool place to cure for at least 4 weeks. After this curing the soap will be hard and long-lasting with a fluffy lather.

Health And Safety

Always wear the gloves and goggles when dealing with lye. It’s a very strong alkaline solution and will burn your skin and eyes if comes into contact with them.

Always run soap recipes through a lye calculator, before you begin to make sure your soap will not have excess lye in the bar. This would make the soap dangerous to use.

Always use digital scales and measure exactly the amount required.
