RE: oderless CA is it safe?
I too have developed a sensitivity to CA so I stay away from it except for very limited applications. That said, although the odorless doesn't seem to present a problem, I suspect the same allergents are present. Case in point, consider carbon monoxide; it's odorless, but deadly. Maybe I'm wrong, but I would recommend playing safe by minimal usage of CA, odorless or otherwise.
Just my 2 cents.
