After successfully tackling the formulation of o/w emulsions...
I'm looking to try my hand at shampoos. The only surfactant I have on hand is sodium lauroyl glutamate in powder form. I would like to start with this then and keep the formulation as eco-friendly and minimalist as possible.
What surfactant blends would perform well with sodium lauroyl glutamate? Would Plantapon LGC Sorb alone be sufficient?
All the shampoo formulations on UL Prospector seem to have a laundry list of surfactants in them. Presumably their purpose is to sell more product. How many surfactants are really necessary for a decently performing shampoo?
