Q&A: Incorporating SCI into a liquid shampoo or body wash?

In yesterday’s post, we reviewed how we might use sodium cocoyl isethionate (SCI) in a liquid product. We found was poorly soluble in water – 0.01% at 25˚C – so we took a look at a few ways we might incorporate SCI into a daily shampoo. Let’s take a look at a few different formulas...
