- 8 oz (225g) potassium hydroxide (KOH) – A key ingredient for making liquid soap (different from sodium hydroxide used in bar soap).
- 32 oz (950ml) distilled water – Prevents contamination and ensures purity.
- 24 oz (680g) oils (such as coconut oil, olive oil, or castor oil) – Provides moisturizing and cleansing properties.
- 2 oz (60ml) glycerin – Adds moisture to prevent dryness.
- Essential oils (optional) – Adds fragrance and additional benefits.
- 1 tablespoon salt (optional) – Helps thicken the soap.
Equipment Needed:
- Large stainless steel or heat-resistant plastic mixing bowl
- Digital kitchen scale
- Slow cooker or double boiler
- Heat-resistant spatula or spoon
- Stick blender
- Glass measuring cups
- Safety gear (gloves and goggles)
Step-by-Step Instructions
Step 1: Prepare Your Work Area
- Wear protective gloves and goggles to prevent irritation from potassium hydroxide.
- Work in a well-ventilated area or near an open window.
- Gather all ingredients and equipment for a smooth process.
Step 2: Mix the Potassium Hydroxide Solution
- Carefully measure 32 oz (950ml) of distilled water in a heat-resistant container.
- Slowly add the potassium hydroxide (KOH) to the water while stirring. (Never add water to KOH, as it can cause a dangerous reaction.)
- Stir until fully dissolved and set aside to cool slightly.
Step 3: Heat and Mix the Oils
- Measure 24 oz (680g) of your preferred oils (e.g., coconut oil for lather, olive oil for moisture, and castor oil for thickness).
- Heat the oils in a slow cooker or double boiler until fully melted.
- Stir in 2 oz (60ml) of glycerin for added moisture.
Step 4: Combine the Oils and KOH Solution
- Slowly pour the potassium hydroxide solution into the heated oils.
- Use a stick blender to mix until the mixture thickens into a paste-like consistency.
- Cover and cook on low heat for 3-4 hours, stirring every 30 minutes.
Step 5: Dilute the Soap Paste
- After cooking, add 32 oz (950ml) of distilled water to the soap paste.
- Stir gently and let the soap dissolve over the next 8-12 hours.
- If the soap is too thick, add more distilled water (a little at a time) to reach the desired consistency.
Step 6: Add Fragrance and Adjust Thickness
- If desired, add a few drops of essential oils such as lavender, tea tree, or peppermint for fragrance.
- If the soap is too thin, dissolve 1 tablespoon of salt in warm water and add it gradually to thicken.
Step 7: Bottle and Store
- Pour the finished liquid soap into clean bottles using a funnel.
- Store in a cool, dry place and use within 6-12 months.
Tips for a Successful Liquid Soap
- Use distilled water to prevent bacterial growth.
- Allow proper curing time for the soap to reach its full effectiveness.
- Adjust the oil ratio to create a more moisturizing or foamy soap.
- Test pH levels to ensure the soap is skin-friendly (ideal pH: 9-10).
Variations
- Moisturizing Liquid Soap – Add aloe vera gel or shea butter.
- Antibacterial Liquid Soap – Use tea tree or eucalyptus essential oil.
- Citrus Liquid Soap – Add lemon or orange essential oil for a fresh scent.
- Exfoliating Liquid Soap – Mix in finely ground oatmeal or coffee grounds.
