Syndet Solid Shampoo Bar Recipe

Syndet Shampoo bars are amazing! Not only do they help reduce the plastic in the world by not requiring a plastic bottle as apposed to liquid shampoo (one 100g bar = three regular bottles of shampoo) try your hand at making some of your own using our recipe below. 



  • Double boiler (a pot inside a pot works well, two x15 litres is ideal).
  • Electronic scales
  • Silicone spatula
  • Measuring cups
  • Food processor
  • Mould


First off the Sodium Cocoyl Isenthionate will need to be turned into a powder by using the food processor (face mask must be worn). Once that is done put it aside as that will be added to melted oils soon.

Get the double boiler up to temperature then add the BTMS-25, Steric Acid, Cetyl Stearyl Alcohol, Polawax, Jojoba Oil, Natural Wheatgerm Oil, Argan Oil, Refined Cocoa Butter. Once everything is all melted you will need to add the Sodium Cocoyl Isenthionate and Sodium Coco Sulfate (mask must be worn for this).

Using the spatula mix, the dry powders into the liquid oils until completely mixed. This Can take about 15 minutes. Once its all mixed in well it should resemble a creamy consistency and will form a skin when it cools.

Once your ingredients are melted, add 10ml of fragrance or essential oil and colour (add small amounts of colour until desired colour is achieved).

Scoop some of the mix out and pour into your mould, it may try setting on you before you get it to the mould so have your spatula ready to help scrape out and flatten the bar in the mould. Once cooled (about 20mins) simply eject it out of the mould.


Our basic high-end solid shampoo bar recipe allows you can add or change out components to suit your needs.

We have scaled this recipe down so it will make around four 100g shampoo bars. To make 40 bars just multiply the recipe by 10.

The PH can be adjusted to suit using citric acid or potassium hydroxide but the finished bar should already have a PH Balance of 5.5 -6.5 which is perfect for hair.
