Has anyone found a good source for non-ionic and/or amphoteric powdered surfactants?
I see tons of powdered options for anionics (and some cationics), but have yet to find anything useful for the other types. I'm trying to create some waterless formulas and would love to have these to round out my surfactant blends. Looking for a sultaine, betaine, or amphoacetate for an amphoteric and a glucoside as a non-ionic, but I'm wide open on suggestions if anyone knows of any other types.
Thanks again everyone!!!
