500 PPM was the standard that was tested for the first EPA registered HOCL product. On the labels it typically shows as 460 PPM even though it is produced at 500 PPM.
Typically the higher the PPM the less stable the HOCL product, so there is an issue of shelf life.
When you have a site generated HOCL that should not be a problem because it will usually be used the same day it is made.

This is still vague.
"there is an issue with the shelf life".
That would be true in the US & in the UK.
Why does UK manufacture the product at a higher PPM, if this makes the product "less unstable"?
Does this mean that 600 PPM product is inferior to 500 PPM product, since the former would be "less stable"?
How long is the shelf life of either product? 30 days? Does the product merely deteriorate by 100 PPM in 30 days, and still is good for general disinfecting .... just 90% effective instead of 100% effective?
The company could do a better job of providing clarity on this, IMO.
