Natural Liquid Soap from Scratch with Tallow
Directions
- 1Weigh out the ingredients in separate containers: tallow, castor oil, and essential oil in one; water and glycerin in another; and potassium hydroxide in a third. WEAR GLOVES AND EYE PROTECTION when handling potassium hydroxide, as it is caustic.
- 2Slowly add potassium hydroxide to the water and glycerin mixture. Do NOT add water to the potassium hydroxide.
- 3Combine the fats with the potassium hydroxide mixture in an Instant Pot on the slow cooker setting using a stick blender until it reaches trace (it will thicken instantly).
- 4Cover the mixture and stir every couple of hours until it turns into a paste (this will take several hours).
- 5To test if the soap is ready, take a small amount and add it to some hot distilled water; shake well. If the solution is clear and not cloudy, the soap is ready.
- 6Pack portions for long-term storage into glass mason jars.
- 7Dilute the soap with distilled water as needed. Test the diluted soap's pH; it should be around 9.
