Coco betaine vs cocobetaine
Hi all.
I hope someone with a chemistry background can help me with this, as I don’t have chemistry background.I understand that cocamidopropyl betaine is not the same as coco betaine. Although many (including some suppliers marketed it as the same thing).
My question, is cocobetaine (one word) the same as cocamidopropyl betaine? All the while I consider coco betaine is also cocobetaine. And it’s hard to find a reliable source for this particular issue.
Thanks

Coco betaine and cocobetaine are the same whereas cocamidopropyl betaine is not. Both are amphoteric surfactants, the former betaine with one of the methyl groups substituted for a mixture of short carbon chains derived from coconut oil (likely mainly decyl and dodecyl) whereas CAPB is betaine with an aminopropyl chain instead which in turn is bound to fatty acids from coconut oil by amid bonds. CAPB should, according to empirical theory, be milder.See graphical illustration for chemical structures HERE. -

It’s stated other name for Cocamidopropyl betaine is also cocobetaine.
I argued that it is not correct but according to another person whom I asked, she said
” this is again incorrectly decoded. Cocobetaine is not the same like INCI: COCO BETAINE. This is actually a very unlucky thing, but CapB in the daily language (other names) is called cocobetaine. In other languages the mixup is less likely, see Kokosbetain (=cocobetaine) vs coco betaine. I agree, this was a very unfortunate choice, but what they put there is correct. It was not the INCI COCO BETAINE mentioned. I would conclude that the book needs attention to details. “Hence, my confusion.
