@ireneista do they have a brand name on them?
@ireneista well that makes it a lot harder to say! i encountered a similar kind of “drain safe” gel pack a while back, and after googling the company was able to determine it was basically liquid fertilizer (nitrogen, water, and a thickening agent) so not ideal but also not anything super toxic either
@Satsuma yeah, it was a long shot, hoping somebody would be sufficiently familiar with the things
@Satsuma speaking for ourselves only, we are no longer able to find real information on the web, about subjects we aren't already experts in, and don't already know some authoritative source for, so.... well, this was what's left
@Satsuma no.
