room temperature soap making

I was researching a new soaping technique when I came across using the room temperature soap making method was the best method to achieve the look for the technique.

What room temperature soap making method?

Well I would not describe as a different method, it is a variant to the cold process soap making method. This being said, I find it takes a lot of juggling and labor out of the cold process method.

Before going any further let me tell you that I am not in a specific camp...some soap makers swear by hot process soap making, certain melt and pourers cannot understand why anyone in their right mind would handle lye and start from scratch and then there are the hard core cold process or nothing soap makers.

I dabble and I am still testing all the methods and have not really defined to one technique. I do love cold process and the products that are accessible with this method.

But I must admit that juggling ice bathes and heat can be trying when I am working on a larger recipe.

room temperature soap making instructions

Remember you need to wear a pair of goggles and gloves when you handle lye. NEVER pour water into lye – ALWAYS pour lye into water.

It is best to have all you soap making equipment and ingredients ready.

Your workspace should be covered.

Mold(s) are prepared and set out.

Print out a copy of the your recipe for a quick reference.

  1. Measure and set aside your essential oils or fragrances and any additives you will be adding to your homemade lye soap recipe.
  2. Weigh out your hard oils and butters place in a container.
  3. Weigh out your soft (liquid) oils and place in a container.
  4. Weigh out your lye (sodium hydroxide) and your distilled water. Place the lye-water solution in a roasting pan or in the sink. This way if it bubbles over it will not burn holes through your kitchen countertop.
  5. Dissolve the lye (sodium hydroxide) into the water LYE into WATER. Make sure that you do this in a well ventilated room or even outside. Take your time to make sure that it is completely dissolve.
  6. When the lye-water solution is clear slowly pour it into the hard oil and butters.
  7. Stir gently with a whisk. The solution is very hot and will burn so take your time. Continue whisking gently until the hard oils and butter have melted.
  8. Stir in your soft oils then begin with the hand blender.
  9. Use a stick hand blender to mix the soap solution. You should be still wearing your goggles and gloves. Be careful not to splash. Continue to mix until you’re the mixture reaches trace (this means that the mixture has thickened enough that when you drizzle some on the top of the mixture, it leaves a trail (trace) on top).
  10.  Add your additives and scents (essential oils - fragrance). Blend all these together for a few seconds with a spatula or hand blender.
  11.  our the soap mixture into mold(s). Cover mold(s) with plastic wrap and cover/wrap these with towels for insulation.
  12.  Let the soap set for 24 to 48 hours or so before taking it out of the mold(s). Unmold and cut the soap into bar. Sometimes I put my molded soap in the freezer a few minutes to make it easier to unmold.
  13.  Place the soap bars on a covered rack to dry out and cure for a minimum of 3 to 4 weeks before using them. 
  14. Enjoy your handmade soap.
