What is sodium hypochlorite pentahydrate (SHC5) ?

Although the existence of “sodium hypochlorite pentahydrate” has been known for a long time, only aqueous solution of about 12 wt% has been industrially available.
Nippon Light Metal Company has succeeded in producing sodium hypochlorite pentahydrate in industrial scale for the first time in the world and launched a new product in 2013, under the name of "SHC5" which is abbreviated name of Sodium HypoChlorite Penta(5)hydrate.
