As you know from my About page, I have a very annoying and chronic skin condition on my arm. Like many of you, I also have Rosacea. Anyway, I made a 100% Extra Virgin Olive Oil soap about 1-2 months ago and I just love it on my skin. I use this soap for my face as well. It is very mild and gentle. It took a while to get used to as Olive Oil Soap does not make large soapy bubbles, but rather has a creamy, low lather. I now enjoy this characteristic of Castile Soap. I do like to add a little essential oil (not much), just enough to take away the olive oil scent. I usually use Lavender essential oil and my Lemon Tea Tree infused olive oil. However, for this soap, I chose to use Lemon Essential Oil and a little Cinnamon Bark Essential Oil.
I bought my first large moulds last week. Each mould holds around 2.5 kilos. I thought that I would make some more Castile soap using Extra Virgin Olive Oil scented with Lemon Essential Oil and a touch of Cinnamon Bark Essential Oil. What I didn't take into account was the small size of my crock-pot! This recipe makes around 3 kilos of soap....So remember....large batch of soap needs a large capacity crock-pot! I felt like I was battling with a gloopy monster that wanted to crawl out of the pot and over my kitchen bench.
My Experiment with a large Batch of soap in a small crock-pot!
Equipment You will need:
- A large 4 litre capacity crock-pot!! Very important! or cut down the quantities by half and run it through a Lye calculator.
- Jug for water
- container for measuring out your Lye
- Digital scale
- Gloves, Goggles or glasses, Long sleeves and legs and feet covered
- Wooden spoon
- long handled stainless steel spoon
- 2 moulds (molds). One 2 kg mould and one 1 kg mould
- hand held blender
- Grease proof paper or Baking paper to line your mould
- 2000 grams Extra Virgin Olive Oil
- 660 grams of Water
- 257 grams of Lye (Sodium Hydroxide) at 4% Lye Reduction
- 28 grams of Lemon Essential Oil
- Cinnamon Bark Essential Oil - to your personal preference
- Measure out the Olive Oil and pour into your crock-pot. I suggest you measure out 1000 grams at a time. I say this as my scales tend to get a little temperamental if I try to go over the 1000 gram limit.
- Have your crock-pot on low and gently warm your oils
- Carefully measure out your quantity of Lye and pour into your quantity of water. Mix thoroughly until the lye water is clear and all the lye is dissolved.
- Let it cool down so that the lye water and Oils are roughly the same temperature. With Hot Process soap making, keeping the Lye solution cool is not so much of an issue as with cold process.
- Gently stir into your oils and mix until well combined.
8. Allow the soap mixture to cook on low. Do not go too far away from your cooking soap or it could grow out of the pot and cause a dreadful mess!
Below are some pictures of the trace at light trace and a heavier trace.
11. Between the 60-70 minutes cooking time, the soap is beginning to enter the gel phase. At last!
13. At 80 minutes into the cook the oil and soap began to separate and it became very difficult to keep it contained in my small pot. At this stage I turned off the heat for 10 minutes and relaxed with a cup of tea!
Mould the soap. I had enough soap for 2 moulds. Remember that Cinnamon has a strong scent so you don't need much. It can also be irritating on the skin if used in large concentrations...so less is more!!
