Hot process soap making is a method where the soap mixture is cooked to speed up the saponification process. Unlike cold process soap, which requires weeks of curing, hot process soap can be used relatively quickly after it’s made. This method is perfect for those who want to see results without a long wait.

Benefits of Hot Process Soap

Immediate Use: You can use the soap within 24 hours, although letting it cure for a week can improve its texture.
Less Mess: The lye is fully reacted during the cooking process, reducing the risk of residual lye in your soap.
Creative Additions: You can easily customize your soap with colors, scents, and additives.

To make your homemade soap, you will need the following ingredients:

20 oz Coconut Oil: Provides excellent lather and moisturizing properties.
10 oz Canola Oil: A great source of fatty acids, it contributes to a balanced soap.
9 oz Distilled Water: Ensures no impurities interfere with the soap-making process.
4.78 oz Pure Lye (Sodium Hydroxide): Essential for saponification, turning oils into soap.
Essential Oils (optional): For fragrance, you can add your favorite essential oils.

Before you start, gather the following equipment:

Crockpot: The main appliance for cooking your soap.
Digital Kitchen Scale: For accurate measurements.
Stick Blender: To mix the soap ingredients efficiently.
Glass or Pyrex Measuring Cups: Avoid metal as it can react with lye.
Soap Mold: You can use silicone molds or line a cardboard box with parchment paper.
Safety Gear: Gloves, goggles, and long sleeves to protect against lye.

Step 1: Prepare Your Workspace

Make sure your workspace is clean and well-ventilated. Wear your safety gear before handling lye.

Step 2: Measure Ingredients

Use a digital kitchen scale to measure the following:

20 oz of coconut oil
10 oz of canola oil
9 oz of distilled water
4.78 oz of lye

Step 3: Melt the Oils

Place the coconut oil in the crockpot and turn it on to low heat. Allow it to melt completely.
Once melted, add the canola oil and mix well.

Step 4: Mix Lye and Water

In a separate glass container, carefully add the lye to the distilled water (never the other way around). Stir until dissolved. Be cautious of the fumes.
Allow the lye solution to cool slightly before proceeding.

Step 5: Combine Lye and Oils

Slowly pour the lye solution into the melted oils while stirring continuously.
Use the stick blender to mix until you reach "trace," where the mixture thickens and holds its shape.

Step 6: Cook the Soap

Cover the crockpot and set it to low. Cook for about 50 minutes, stirring occasionally.
Check for doneness by performing a zap test: touch a small amount to your tongue. If it doesn’t zap, it’s ready.

Step 7: Pour into Molds

Once cooked, pour the soap mixture into your prepared molds.
Smooth the top and allow it to set for 12-24 hours.

Step 8: Cut and Cure

After the soap has hardened, remove it from the molds and cut it into bars.
Let the bars cure for a few days to improve hardness and texture.

Is Canola Oil Good for Soap Making?

Yes, canola oil is an excellent choice for soap making. It is rich in fatty acids and helps create a balanced soap that is moisturizing and gentle on the skin.

Can I Use Other Oils?

Absolutely! You can experiment with different oils. Olive oil, palm oil, and even animal fats can be used in combination with canola and coconut oil for varied properties.

How Long Does Hot Process Soap Last?

When stored properly, hot process soap can last for several months. Keep it in a cool, dry place to extend its shelf life.

Making homemade soap with canola and coconut oil using the hot process method is a fun and fulfilling project. Not only do you get to customize your soap to your liking, but you also create a product that is free from harsh chemicals. With the right ingredients and equipment, you can enjoy the benefits of natural soap that nourishes your skin. Happy soap making!
