Sulfate-Free Conditioning Shampoo

 

This shampoo formulation is prepared using a blend of alkyl glucoside surfactants. These are nonionic surfactants derived from natural sources and have been found to be significantly less irritant to skin or eyes. The formulation avoids the use of common sulfated surfactants such as sodium lauryl sulfate, SLS, or sodium laureth sulfate, SLES, etc. It uses a cationic conditioning polymer.

Preparation Procedure:

 

In a suitable formulation vessel, at room temperature and under steady mixing add item 7 into 1 and mix until all the powder dissolves in about 1 hour. Raise the pH to about 8 -9 and mix for an additional 1 hour. Add items 2, 3, 4 and 5 while mixing. Add item 6 and mix well. Lower the pH to 6.0 and add item 8. Mix for 30 minutes.  Measure pH and viscosity and adjust as needed.

 

This shampoo composition will be clear and with a Brookfield viscosity of about 6,000 to 10,000 mPa·s.  Note that the viscosity of the shampoo can be adjusted by increasing or decreasing the concentration of the thickener, item 7.

All ingredient amounts are given assuming the ingredients were supplied 100% pure. Formulators are advised to measure the total active mass of their ingredients and adjust the composition with water.
