Q&A: Can non-ionic surfactants contain electrolytes? Can we use non-ionic surfactants with something that can’t tolerate electrolytes, like Aristoflex AVC?

by

In the monthly Q&A, Melinda asked, Hey Susan and everyone! Can non-ionic surfactants contain electrolytes? I ask because I am curious if we can use a high ASM of non-ionic surfactants with thickeners that can only handle a certain amount of electrolytes. For example could something like Aristoflex AVC that can’t handle electrolytes at all be...

Q&A: How would you modify a shampoo bar formula to be a “no more tears” product? Part five, testing and alter the final pH

by

Welcome to part five of this series on how we might create a “no more tears” kind of shampoo bar using various anionic, non-ionic, and amphoteric surfactants. In part one, we reviewed the surfactants that Alexander noted she has in her workshop – sodium cocoyl isethionate (SCI), foaming apple surfactant, decyl glucoside, and Cocamidopropyl Betaine –...
