salt thickening sulphate-free
I have been experimenting with Innospec's sulphate-free blend, ISELUX SFS. It thickens with salt. My question is very simple. Which of its ingredients are the surfactants that thicken with salt?
Sodium Lauroyl Methyl Isethionate
Sodium Cocoyl Isethionate
Sodium Methyl Oleoyl Taurate
(it also contains CAPB but that's not the one)
