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)  

Syndet Solid Shampoo Bar Recipe

This is a basic high-end solid shampoo bar recipe, you can add or change out components to suit your needs.

We have found using our method of mixing and heating the components make a super solid bar that will not fall to bits when used as the majority of the cold pressed bars will.

To get started you will need the following…

A double boiler (a pot inside a pot works well) 2x15L will be ideal. Electronic scales, silicone spatula, measuring cups, food processer.

We have scaled this recipe down so it will make around 4x100g shampoo bars. To make 40 bars just times recipe by 10 and so on.

First off the Sodium Cocoyl Isenthionate will need to be turned into a powder by using the food processer (FACE MASK MUST BE WORN!!!!)

Once that is done put it aside as that will be added to melted oils soon.

Ok now the fun part!!

Get the double boiler up to temperature then add the following…

50g BTMS-25

25g Steric Acid

25g Cetyl Stearyl Alcohol

25g Polawax

5ml Jojoba Oil

1ml Natural Wheatgerm Oil

5ml Argan Oil

10g Refined Cocoa Butter

Once everything is all melted you will need to add the following… (MASK MUST BE WORN FOR THIS)

100g Sodium Cocoyl Isenthionate

100g Sodium Coco Sulfate

Using the spatula mix the dry powders into the liquid oils until completely mixed (Can take about 15mins)

Once its all mixed in well it should look like a creamy consistency and will form a skin fast when it cools.

Now is the time to add your fragrance and colour if you choose to.

For this batch size I would recommend 10ml of fragrance and for colouring just add small amounts to batch until desired colour is achieved.

Next step is to scoop some of the mix out and pour into mould provided, 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 and boom !!! you just made a real syndet shampoo bar!


This Recipe is designed so you can play around with adding extra additives.

You can add an extra 10% oils of your choice to this recipe without effecting the hardness too much. Also 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  and that is perfect for hair.
