Sulfate Free Shampoo Bar

Shampoo bars are sustainable and easy to use. They last long and are also efficient.
This Shampoo bar is Sulfate free and is made of single powder surfactant SCI,
which is milder and suitable for many hair types. It is a conditioning shampoo bar,
which doesn’t make hair dry.

 

Note on ingredients used:

 

 

Surfactants used

SCI: Sodium Cocyl Isethionate (Anionic Surfactant) – SCI is also known as baby
foam, it is gentle and milder surfactant which has good foam and rinsing properties.
Coco Betaine (Amphoteric surfactant) & Decyl glucoside (Non-ionic surfactant) –
These are the secondary surfactants which make shampoo bar more milder and
also help to solubilize SCI.

 

Conditioning ingredients:

BTMS 50- It is the popular hair conditioning ingredient. BTMS makes hair soft and
bouncy.
GHTC (Guar Hydroxypropyltrimonium Chloride)- It is also hair conditioning
ingredient which adds slip, reduces frizz.
Polyquat 7- Adds shine and reduces frizz.

 

Moisturising ingredients:

Hydrolysed Rice Protein-Hydrolysed proteins help hair look healthy. Rice water and
rice protein are widely used in hair products in certain countries.
Glycerine- is the most effective, hydrating and moisturizing ingredient.
Spirulina extract- Strong anti-oxidant which also helps hair look healthy.

 

Other ingredients:

CCTG- is a kind of natural silicone.
Cocoa butter, Stearic acid- adds conditioning properties. Also makes shampoo bar
hard. But the disadvantage in adding oils and butters is that it reduces foam. If you
don’t mind less foam, this would be your go-to shampoo bar.

surfactants are dissolved. ( Do not over heat)

remove the beakers from heat.

and mix it with your hand.(Note: Ingredients would be at higher temperature,
so do not mix with hands. Use gloves or spatula)
5) Add cool down ingredients when it is at room temperature.
