Hello Everyone!

Here's a recipe for a basic shampoo bar using Sodium Cocoyl Isethionate (SCI) and Cocamidopropyl Betaine (Coco Betaine).

Ingredients (Percentages):

1. Sodium Cocoyl Isethionate (SCI) - 50%

2. Cocamidopropyl Betaine (Coco Betaine) - 20%

3. Coconut Oil - 10%

4. Olive Oil - 10%

5. Shea Butter - 5%

6. Essential Oil (Optional, for fragrance) - 5%


1. Heat-resistant mixing bowl

2. Double boiler or microwave for melting oils

3. Soap molds or silicone molds

4. Spatula or spoon for mixing

5. Digital scale for measuring ingredients

6. Protective gloves and goggles (optional but recommended)


1. Prepare Your Work Area: Ensure your work area is clean and free from any contaminants. Put on your protective gear if you're using any.

2. Measure Ingredients: Using a digital scale, measure out the required amounts of SCI, Coco Betaine, coconut oil, olive oil, and shea butter. Place them in a heat-resistant mixing bowl.

3. Melt Oils: Melt the coconut oil, olive oil, and shea butter together using a double boiler or microwave. Heat them gently until fully melted and combined.

4. Mix Ingredients: Once the oils are melted, add the SCI and Coco Betaine to the bowl. Mix everything thoroughly using a spatula or spoon. Ensure that the SCI and Coco Betaine are evenly distributed throughout the mixture.

5. Add Essential Oil (Optional): If you want to add fragrance to your shampoo bar, now is the time to add essential oils. Stir in the essential oil until it's evenly distributed throughout the mixture.

6. Pour into Molds: Carefully pour the mixture into your soap molds or silicone molds. Tap the molds gently on the counter to release any air bubbles and ensure the mixture settles evenly.

7. Let It Set: Allow the shampoo bars to cool and harden at room temperature for at least 24 hours. You can speed up the process by placing them in the refrigerator.

8. Remove from Molds: Once fully hardened, carefully remove the shampoo bars from the molds. If they're stuck, you can gently push on the back of the mold or flex the mold to release them.

9. Let Them Cure: To improve the longevity and performance of your shampoo bars, allow them to cure for an additional week in a cool, dry place before using them. This allows excess moisture to evaporate and the bars to harden further.

10. Enjoy Your Shampoo Bars: Once cured, your shampoo bars are ready to use! Simply wet your hair, rub the bar between your hands to create a lather, then massage the lather into your hair and scalp. Rinse thoroughly with water.

Feel free to adjust the recipe to suit your preferences, such as adding different oils or adjusting the fragrance level. Always remember to perform a patch test before using any new skincare or haircare product, especially if you have sensitive skin or allergies.
