coco glycerides is a different ingredient from cocamidopropyl betaine. I'm not sure I understand your post lucyprimrose. I don't see glycerides in the first ingredient list.
Juana, I get adding oils to conditioners to make them better. I did this with the cheapy conditioners (V05) as they usually do not have oil in them. I don't think there is anything wrong with doctoring up a product by adding oil for your personal use, but really, I would rather just buy a product that works for my hair.
