The only difference is that there is more variability in the length of the carbon chain in the molecule. They will both be equally irritating and are equally natural. I can't think of any reason to prefer one or the other from the consumers point of view, but if you are a formulator you might find that the coco form might give you better stability in an emulsion. When I see sodium coco sulphate on the ingredient list of a product that claims to be in some way natural, green or safe I tend to assume that they are having a laugh at my expense.

Thanks. Do you know anything about Sodium Coco Sulphate - is it a milder version of SLS, or is it just the same thing under a more touchy-feely name? Interesting. Thanks.
