Can you suggest a low voc/odor caulk for around vent returns?

15 years ago

I'd like to seal the gap between drywall and the metal vent boxes in my 2nd floor ceiling. Any suggestions on a caulk that is low voc and low odor? Dap recommended their Dynaflex 230, but the tube is covered with inhalation warnings...dizziness, birth defect, cancer. This is going in a child's room, so i'd like something that doeasn't off-gass for long. I tried a really simple latex once and it took over a week to really cure and stop smelling. Any recommendations?
