Is there any harm to batching for too long (~10 days)? Still waiting for my synthrapol order and wondering if I should grab a small bottle from the art store

Honestly, 48 hours is all you need. You wont really see much of a difference (if any at all) by batching longer than that.

What I meant was, if I don’t have the opportunity to wash them out in a few days will they be get muddy or ruined?

Ohh ok i gotcha. I thought you meant you were maybe experimenting. In that case, i think youll be fine since you mentioned theyd be closed up. Just make sure theyre sealed well and sitting on a level surface.

The only thing I'd be worried about would be mildew or mold. Not sure how that stuff gets affected by the elevated ph.

You can just wash with dawn and laundry soap if you want. Just be extra thorough with the hand washout (if you have lots of blue its gonna suck) I actually do this all the time, saving my synthropol for the largest loads and sweatshirt material loads. Make sure to do two rinses in the cycle though. You still might get some bleed after that, but I just wash the items with darks the first couple regular washes times and I dont have issues.

I haven't batched that long, but I seriously doubt there will be any issues. Once the fabric dries, the reaction process stops.
For what it's worth, I stopped using synthrapol once I ran out of my bottle. I use blue dawn dish detergent and haven't had any issues. Use that advice at your own risk though.
What if they’re sealed in plastic boxes that keep the humidity in?
As far as I know the procion dyes stop reacting after 48 hours I think I got that off the dharma website but not 100 on that
