Hi Naomi,
I liked your post a lot and find it very help full.
Could you tell me what percentages do you use of CSI and Cocamidopropyl Betaine?
Have you ever use Decyl Glucoside ? or SLSA? I also have those two surfactants.
I bought them to create a bar shampoo that I did for one year but I got tired and I want to make liquid shampoo I just can’t find a recipe with the percentages for these surfactants.
Any help you could give me I would truly appreciate it.
Best, Venus
