I've yet to try this but thought this might be helpful. A simple recipe found online for a mini personal deodorizer that could come in handy sometime! Perhaps even positioning near the pits(with a tight T-shirt?), or skin folds under the breast area. Be careful w/ the charcoal, it could get messy.

"I use a small spoonful of activated charcoal in the round cotton pads 'strategically' placed where the sun don't shine, to absorb gas odor. It works unbelievably well to absorb gaseous odor.

Cut an edge off the pad, like a pita, separate the cotton inside and place a small spoonful inside. ~~Wrap the pad in one layer of a piece of paper towel~~ (to prevent leakage). This is much easier than opening a charcoal capsule, which is a mess to do. I keep about a cupful of this in a small tupperware and store the rest. Do NOT drop it or spill it.

After bariatric bypass surgery, internal charcoal caps do not work anymore. This WORKS."
