by

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...
