OK so in have finished a 5 day test with odorlos powder.
I made a paste and smeared it on a Marlon, plain nylon, rubber, hdpe, red solo cup, PVC, aluminum, brass, bronze, and cpvc. No damage to any container after keeping them in a damp setting. All samples were wet the whole time like you would expect in a plumbing situation with a solution of urea added. (Urea ice melt was used in lieu of me peeing in the buckets.)
When I added bleach, the rubber bulged. Off the shelf jug of Muriatic acid that I did not dilute damaged the nylon and destroyed the solo cup, ate the rubber. It did this whether or not odorlos was used.
Where the issue arose was with toilet bowl cleaner. It softened the rubber and seemed to cause etching on the cpvc and nylon fittings. The addition of odorlos appeared the accelerate the damage, but I believe this was due to heat given off by the reaction between the nitrogen in the odorlos and hydrous compounds in the bowl cleaner.
It is safe to say, and I am sorry that the OP has a plumbing issue, but odorlos was not the culprit.
I am going to look more at the bowl cleaner issues to see what happened.
