Hot Process Soap Making

When I started formulating recipes for the natural beauty workshop, I only had a solid soap method under my belt. While I still love making cold soap, I was so excited to try something new. Over the past few months I have been experimenting with soap making hot process and it was a Boom!

From beginner to beginner, here are some observations from my own experience with hot processes:

Never leave your hot process soap alone during cooking. As the recipe moves through the cooking phases, the soap can actually grow and expand. It often has to be stirred. If you don’t keep it in mind, the soap can actually overflow the jar-which creates a volcano of raw soap!

I was surprised how long my hot soap stayed soft. Even though I used stearic acid in my recipe, which usually gives a harder bar, it took me up to a week for my soap to be completely cured.

My finished bars were much smoother than expected! I’ve always heard of hot soap that looks “rustic”, but my bars looked rather sophisticated. The top wasn’t as smooth as my cold treatment soaps, but I doubtful they could be quite altered using parchment or plastic wrap.

Air inclusions can be frustrating. After a few batches, I started perfecting my technique to avoid these hot traps, but I still find the occasional hole in my soap here and there.I found that it helps to distribute the soap evenly in the shape by pressing all the corners and then stomping it well. I used a spatula to get into the Corners and also tried the good old elbow grease (just hit the mold on the table to release the air pockets). I would like to hear more tips on how to remove air inclusions in hot soap.

Each batch of hot soap behaved differently-even if the same recipe was used! This part really surprised me. Even using the same recipe, I noticed differences in the phases that the soap went through and how long those phases lasted.
Hot soap making process is so much fun! All the staff would get together when I did batch by batch. Each time, we were amazed by the phases that the soap went through.

I can’t wait to make more hot soaps. Stay tuned for the Hot Process Soap Recipes Soon! In the meantime, we’d love to hear all of our HP soap experts share their tips and tricks. Share Your top Tips in the Comments below.
