Welcome to part three 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 –...

Welcome back to this series on creating a “no more tears” solid shampoo bar! 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 – looking at their pH and potential irritation to our eyes. We need another...

In this month’s Q&A, Alexandra asked, I have two kids neither of whom are great at keeping shampoo suds out of their eyes. How would you modify a shampoo bar formula to make it a no-tears one? I currently have SCI powder, decyl glucoside, cocamidopropyl betaine, and foaming apple surfactant in my stash, but I’m happy...
