Sulphate free shampoo with sodium lauroyl sarcosinate
SHAMPOO FORMULATION with Sodium Lauroyl Sarcosinate
ABOUT THE INGREDIENTS:
This is a Sulphate free shampoo with natural surfactants.
It is a clear shampoo; you can add colour or use a fragrance with transparent colour for more clear (similar to water) shampoo.
• Sodium Lauroyl Sarcosinate: Anionic surfactant which is mild and has good foaming properties.
• Coco glucoside: Non-ionic surfactant which increases the mildness of the shampoo. Decyl glucoside can be used but the foam will differ.
• Coco Betaine: Amphoteric surfactant which boosts foam and also helps in increasing viscosity.
Conditioning ingredients:
• Glycerine(optional) is a humectant which adds moisture to the hair.
• Polyquat 7: It is a cationic conditioning agent which reduces frizz and increases shine.
• Hydrolysed proteins (Hyd. Rice Protein, Hyd. Wheat Protein): Hydrolysed proteins help in repairing damaged hair. Other hydrolysed proteins like oat protein, milk protein can be added.
• Olivem 300: It increases foaming in a shampoo and also adds emollient properties.
Other ingredients:
• Sodium gluconate is a natural chelating agent which stabilises the formulation and also prevents foam reduction when hard water is used. EDTA can also be added.
• Polysorbate 80: To solubilise fragrance oil in shampoo. It helps in making clear shampoos when oils need to be incorporated in water based formulations.
• Salt: natural thickening agent. To make a more thick shampoo, gums like xanthan gum or polymers like carbomer can be used.
• Sandalwood fragrance oil for a nicer scent. Fragrance oil can be any but the ratio between F.O and Polysorbate 80 varies with fragrance oil. It needs to be tested before incorporating to shampoo directly otherwise shampoo will be cloudy or milky.
• Lactic acid: to reduce the pH to 5.5. Citric acid is a good alternative
• Euxyl k712: Preservative for a longer shelf life.
