Dear gaagn,

Shampoo solution is a better emulsifying agent for the reason being:

The most common ingredient in shampoos is also the most common detergent in use in other products, a class of surfactants known as straight-chain alkyl benzene sulfonates. An example is Ammonium lauryl sulphate, or its sodium relative, or the slightly larger related molecule ammonium lauryl ether sulfate, sometimes abbreviated as ammonium laureth sulfate.

These detergents work best in water that has little calcium and magnesium, as these elements bind to the detergent and make an insoluble scum. So tetra sodium EDTA is used to sequester the calcium and magnesium from the detergent, while keeping them soluble, so they rinse away without scum.

All the best.
