Q&A quickie: What can you substitute for LSB in a solid shampoo bar (syndet bar)?

I don’t think we can find the surfactant blend called LSB any more – in North America at least – as it’s been altered to have a very short shelf life of 6 months, so what can you do as a replacement? The short answer is that you can use any liquid surfactant suitable for...

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

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 three, increasing mildness by combining surfactants 

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 –...

Q&A: How would you modify a shampoo bar formula to be a “no more tears” product? Part two, reviewing the solid surfactants

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...

Q&A: How would you modify a shampoo bar formula to be a “no more tears” product?

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...
