Put on your face mask, making sure it's nice and tight. Weigh the dry powdered surfactants into a separate heatproof bowl.
43 g Sodium Cocoyl Isethionate, 19 g Sodium Lauryl Sulfoacetate
Weigh the BTMS 25 and the cocoa butter into a heatproof container, then melt the butter and BTMS wax in the microwave until completely melted.
4 g BTMS-25, 5 g Cocoa Butter
Whilst the butter is melting, mix the wheat protein, essential oil, and the preservative into the Cocamidopropyl betaine.
4 g Hydrolyzed Wheat Protein, 1 g Orange Essential Oil, 1 g Preservative, 23 g Cocamidopropyl Betaine
Stir the Cocamidopropyl betaine (along with the mixed in protein, essential oil and preservative) into the powdered surfactants until well blended.
Add the melted wax and butter to the rest of the ingredients and mix until you have a good smooth paste and you are satisfied that all the ingredients are fully combined.
Spoon the mixture into the mold pressing it down firmly so that you get it into all the corners of the mold and no air pockets are left. For a nice smooth surface, place a piece of baking parchment/waxed paper on top, and firmly press and stroke across the top of it. Then, pop the mold into the freezer for around 30 minutes until it's hardened enough to remove it from the mold.
The DIY shampoo bar will need a few days, to harden. You can use it straight away, however, I prefer to leave mine for a week. This makes the soap nice and hard so it lasts longer and is less messy when you are using it.
