Instructions:

  • 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
    step 1: combine your dry surfactants in a bowl
  • 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
    Step 2: In a heatproof beaker, combine your wax and butter then melt in the microwave using 30 second bursts
  • 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
    Step 3: In another beaker, combine your liquid surfactant with your essential oil and preservative, stir well
  • Stir the Cocamidopropyl betaine (along with the mixed in protein, essential oil and preservative) into the powdered surfactants until well blended.
    Step 4: Combine your liquid surfactant, essential oil and preservative mixture with your dry surfactants
  • 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.
    Step 5: Add your melted wax and butter, stir well
  • 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.
    Step 6: Using a spatula, press the mixture into your molds
  • 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.
    Step 7: Leave for 30 minutes, then remove from your mold and leave for a further 24 hours to harden
