Most mild amphoteric surfactant?
Hi, in search of a more ‘mild’ amphoteric surfactant to blend with my nonionic shampoo. Not sure if it exists…but I’m looking through the options.
CAPB - As a person with highly sensitive skin, I’m aware CAPB has potential contaminants ( also potential harm to aquatic life).
Cocomidapropyl Hydroxysultaine - I’ve tried, but I think it’s giving me the itches.
Sodium Cocoamphoacetate - I read may have potentially interfere with the body’s ability to create lymphocites (further research needed)
Coco Betaine - I’ve heard is more irritating that CAPB, but less chemically processed.What are your experiences with Sodium Lauroamphoacetate, Coco Betaine, or potentially other amphoterics?
Perhaps ill just eliminate amphoterics altogether and stick with just nonionic

A very interesting topic. Environmental and toxicological claims aside, from the various charts I saw, Cocomidapropyl Hydroxysultaine is the mildest of the listed. My anecdotal experience confirms it (I haven’t tried coco betaine, isn’t it non-ionic?)
I also tried Sodium Babassuamphoacetate

for me it’s no different to CAPB (tried in the same product with only one ingredient changed, kept the ASM, not a proper test but better than nothing). On the negative side it is orange and it might not be desirable because it will color the product.I also recently noticed Shea Butteramidopropyl Betaine
this https://simply-ingredients.com/collections/all/products/shea-butter-surfactantsounds as an interesting ingredient but haven’t tried yet.

As ngarayeva001 said Hydroxysultaine is the mildest of these but if if you use them alone they will be irritating. Maybe because they cant clean enough
