The surfactants mentioned above are the "Devil that doesn't exist", and rarely even make it into discussion.

Frequently, Roundup is granted an undeserved pass, based on glyphosate's safety record.   

It's my impression that this conflation has been encouraged by the manufacturer.


The sierra club covers this difference in their glyphosate fact sheet:
