Ingredients

32.5 g Sodium cocoyl isethionate (SCI) in powder form

11 g cocamidropopyl betaine

3 g cocoa butter

1 g jojoba oil or coconut oil

0.75 g kaolin clay

0.5 g bentonite clay

1 g essential oil

0.25 g eco preservative

1. It is recommended to use a mask when handling SCI as it can be irritating if you breath it in. First, we will weight the SCI powder.

2. Add the remaining ingredients, except the cocoa butter.

3. Melt the cocoa butter at low heat in a water bath. Once melted, add it to your mixture and mix well.

4. Add the preservative and essential oils once it is cooled down.

5. Add the shampoo mixture into a clean mould or make the shape with your hands.

6. Let it harden in the freezer for an hour and, after that, it is ready to be used!
