Transcript:How to Make Cold Process Soap

Hi I'm Jen D'Amore for About.com, and this video is all about how to make cold process soap using a recipe and tips from About.com's candle and soap making site.

Ingredients for the Lye Solution for Cold Process Soap

Let's break this into two parts. Part I is making the lye water. To do this you'll need:
  • safety protection, including goggles, chemical resistant rubber gloves (and cover as much skin as possible)
  • 6.9 oz of lye and a jar to weigh it in
  • 16 oz distilled water
  • a large Pyrex or other heat resistant pitcher with a lid
  • a scale
  • a mixing spoon
  • a large bottle of vinegar, just in case

Make the Lye Solution for the Cold Process Soap

Lye is caustic, and will burn your skin and especially your mucous membranes. Vinegar neutralizes it, so have it on hand in case of spillage. You can also use it to clean any area that may have lye dust.

Work in a well-ventilated area and put on your personal protective gear. First, set the scale to tare the pitcher. Weigh out the water and set aside. Reset your scale to tare the glass jar. Slowly weigh out 6.9 oz of lye, minimizing dust or spillage. Be exact with your measurements.

Slowly add the lye to the water (in that order) in the pitcher and stir. This will heat up to as high as 200 degrees. Cover it and put in a safe place for a few hours to cool to about 100 degrees. You probably want to label it with a warning for anyone that may come in contact with it and keep it out of reach of children or pets.

Ingredients for the Cold Process Soap

When it has cooled, you're ready to make the soap. For this you'll need:
  • the lye solution you just made
  • the safety protection and the scale
  • 40 oz of olive oil
  • a big pot for weighing and mixing
  • 10 oz of coconut oil
  • a heat tolerant container to weigh and heat it in
  • 1.5 to 2.2 oz of fragrance
  • essential oil
  • colorants of your choice and a small container to weigh it
  • a spatula
  • thermometer
  • a stick blender
  • soap molds

Make the Cold Process Soap

Set a tare weight, and weigh the coconut oil. Slowly heat it to melt it to liquid form. Meanwhile, in the big pot weigh the olive oil. When the coconut oil has melted, add it to the olive oil. Use the spatula to get out as much as possible.

Check the temperatures of both the lye water and the liquid oils, make sure they are not higher than 100 degrees. When they're ready, add the lye water to the oils in the pot, and without turning it on use the stick blender just to stir for a bit. Then turn on the stick blender in short bursts until you reach trace.

Trace is the point of no return, it's when the solution has transformed into soap, and if left to sit, the solution will not separate. You'll know trace has been achieved when you drizzle some of the mix over the surface, and see that trails are left behind.

Now is the time to add any fragrance or exfoliants, mix it, and pour into molds.Let it set, release it from the molds, and allow it to cure for a couple of weeks.
