Ended up receiving a package with ten milliliters total. Analyses took place covering the preservative as well. It appears totally transparent though I still haven't sampled any myself. Folks from the group order mentioned applying it without trouble. Another buyer received a portion too but I'm unsure if they have tried theirs already.
I've noticed this option exists now and I'm curious whether others have tried it out already. I've got another version ready but it would be good to have an extra option available if needed.
