## Ingredients

- 1000 grams Avocado Oil
- 210 grams Potassium Hydroxide 90%
- 250 grams Distilled Water
- 250 grams Glycerin
- 30 grams Peppermint Essential Oil
- Water to reconstitute

## Instructions

1. Weigh out 1000 grams of avocado oil into a glass measuring cup.
2. Pour the avocado oil into an Instant Pot set to the slow cooker setting on medium.
3. Place another glass measuring cup on the digital scale and zero it out.
4. Weigh out 210 grams of potassium hydroxide into the glass measuring cup.
5. Weigh out 250 grams of distilled water into a separate glass measuring cup.
6. Weigh out 250 grams of glycerin into the same measuring cup as the distilled water and stir.
7. Weigh out 30 grams of peppermint essential oil into a small beaker.
8. Add the peppermint essential oil to the oil in the Instant Pot.
9. Carefully add the potassium hydroxide to the water and glycerin mixture, stirring with a glass stirring rod until dissolved. Do not add water to potassium hydroxide.
10. Use an infrared thermometer to check the temperature of the potassium hydroxide solution. It should be below 175°F (79°C).
11. Check the temperature of the oil in the Instant Pot. It should be between 160-175°F (71-79°C).
12. Gradually pour the potassium hydroxide solution into the oil in the Instant Pot while continuously mixing with an immersion blender.
13. Continue blending until the mixture reaches a thick, trace-like consistency (about 7 minutes), resembling a thick applesauce.
14. Cover the Instant Pot and cook the soap paste on the slow cooker setting, stirring every half hour, until it becomes translucent and gel-like. This took about 4 hours.
15. To test for readiness, add some warm distilled water to a small jar.
16. Add a small amount of the soap paste to the jar with water, close the lid, and shake well.
17. If the solution in the jar is clear, the soap paste is ready.
18. Add water to the Instant Pot with the soap paste to dilute it, filling it up.
19. Stir the diluted soap, cover the Instant Pot, and leave it on low overnight to dissolve completely.
20. The next morning, check the pH of the dissolved soap using a universal indicator paper; it should be around 9.
21. Pour the liquid castile soap from the Instant Pot into glass jugs for storage.
22. For hand soap, fill a hand soap dispenser about a quarter full with the concentrated liquid castile soap.
23. Top off the hand soap dispenser with tap water and shake to mix.

## Equipment

- Immersion blender
- Silicone spatula
- Infrared thermometer
- Small glass jar with lid
- PH test strips
- Glass jugs
- Funnel
- Hand soap dispenser

## Tips

- When mixing water with potassium hydroxide, always add the potassium hydroxide to the water, not the other way around.
- Always wear gloves and eye protection when working with potassium hydroxide, as it can burn your skin.
- Ensure the potassium hydroxide solution and the oil are both between 160-175°F (71-79°C) before mixing them.
- An immersion blender helps to quickly emulsify the mixture; otherwise, you can mix by hand, which will take longer.
- To test if the soap paste is ready, dissolve a small amount in warm distilled water; if the solution is clear, it's done.
- The final pH of the dissolved soap should be around 9.
- The concentrated soap paste can be stored for at least a couple of years in a glass container.
- When diluting for use, tap water can be used, but it might make the soap cloudy.
