Finding the right depends has been a challenge. With that said I have found the best fit and ones but I have several packs that do not work.

Have you tried calling local NHs to see if they accept them? Otherwise you can post it on Nextdoor.com and have interested parties privately message or text you.

If you tape the package and the remainder are obviously new, like not taken out of the package new, you can donate them. I see them at thrift stores all the time like this.

I would also look for a local diaper bank, they will have resources for adult incontinence donations.

Would love it if you told those on Forum which products worked well for you and which ones did not work. Sounds like you did your research. This question is often asked here.
As to accepting open packages, do call around. As a former nurse I never worked anywhere where open packages were accepted, but there certainly may be a one on one who would love to receive this. You might check food pantry as I volunteered in one that actually opened and made smaller packages available; they did the same with dog food. Opened packages and divided product. People definitely took both. This was some time ago. I doubt they would do so today.
