Shampoo syndet bars from scratch

Gentle Solid Shampoo Bars: Yields 2 x 80g bars

There has been some talk about solid shampoo bars having high PH which is not particularly good for hair.  A nice, PH balanced shampoo will keep your hair and scalp in good condition.  It is all about the chosen surfactants.

We will keep updating and adding great information for changing up the formula for an enhanced finished product.

Benefits of our Solid Shampoo (Syndet)

  • Ease of travel
  • Gentle and silky
  • Easy to make
  • Low PH

The word “syndet” is derived from “synthetic” combined with “detergent”. Technically it refers to the binding that occurs between different detergents, also called surfactants. These detergents, which have an affinity for oils and repel water, surround dirt with small structures that are then removed by water.

Gentle Solid Shampoo Bar Recipe Yield approx 300 grams 

1st Heated phase

1 1/2 tsp 1.7% Cocamidopropyl betaine (heat separately and add the panthenol powder if using it) Surfactant.   Can be substituted with Foaming Apple for a more mild ingredient
5.5 TB SCI 37.7% Sodium Cocoyl Isethionate gentle surfactant (crush up in a baggie if not using a powdered form.  Melting is preferred to pressing your surfactant. 
2nd Heated Phase
1 3/4 tsp 3.4% Kokum butter. (if using volume and not % melt to measure)  Moisturizer & conditioner
1 3/4 tsp 3.4% BTMS 25 Conditioning emulsifier 
1  tsp 1.9% Cetyl Alcohol emollient, emulsifier. Can be substituted with Brassica Alcohol for a palm free ingredient

3/4 tsp 1.5% protein of choice (Hydrolyzed Silk or Baobab Protein)  improves elasticity, resiliency, and restore the moisture balance for smoother and softer hair.

1/4 cup plus 2 tsp 33.28% Lathanol SLSA, Sodium lauryl Sulfocete. Surfactant powder for foam. 

Cool-down phase 

2 TB 13.7% alpha-olefin sulfonate or Caprylyl/Capryl Glucoside due to the low ph in these mild surfactants  

Optional

1/2 tsp 1.14% Panthenol powder  Humectant that helps give body & shine and detangling properties to hair. It can cause curly hair to frizz, however.  If you omit this, add this % to the SCI or SLSA (add to 1 heated phase.  Be careful to not let it burn)

1/2 tsp .57% scent  (more can be added depending on your choice of scent)

Optional: Water-soluble dye or micas for color. Manganese Violet is known to brighten grey hair and reduce the brassiness in blonde.

 Directions:

Melt your 1st heated phase over the stove at medium heat.  At the same time in a separate vessel heat, your 2nd heated phase by totally melting the kokum butter then add remainder of the 2nd heated phase and continue to heat until melted. We recommend melting the entire formula to achieve nice hard bars that do not all apart half way during use.  Combine both heated phases mix well and remove from the heat.  If you find the 1st heated phase needs more moisture, multiply the Cocamidopropyl betaine by up to 3 times.  It may take your final bar longer to harden.

Mix in your cool down phase.  If adding colour, this is the time.  

Allow to cool to 80 Degrees Celsius or less and mix in the Optiphen Plus, and scent, colour (judge this and use sparingly) if using and combine.

Press tightly into your mold and allow to firm up. (Not a smooth batter so beware) Place in the freezer for a couple of hours. Pop them out of the mold and let them sit for 24 to 48 hours to dry out further.  No need to cure or cover.  Can be used after 48 hours.  Lather the bar in your hands at first, add to your wet hair and then use the bar directly on your hair for more lather.

Water friendly ingredients such as clays, plant extracts and starches can make the bars too crumbly, keep their usage low.
