I've seen it in tankers, 55 gallon drums, 300-gallon totes, you name it. It's stable at cool temps.Storebought bleach is never over 5%. 80-90% solution is common for industrial use. The 15-17% solution you speak of is common for industrial laundry applications.Most hypo used is 15-17%, as the higher concentrations degrade far too quickly. Even 17% hypo is only good for a few months before is degrades.
I'm not sure you can even buy 80-90% hypo outside of lab scale amounts.
17% is what is used for wastewater treatment, as anything stronger tends to degrade too quickly. It is delivered via tanker truck. What industries use 80%-80% and what the hell is it stored in?
