Additional information

According to Regulation (EC) No. 1907/2006, Annex IX, Column 2, simulation testing on biodegradation in water and sediment is not necessary if the substance is readily biodegradable. Since phosphoric acid, potassium salt (2:3), dihydrate is inorganic, the biodegradation concept (decomposition of organic molecules into smaller ones and eventually to CO2, minerals and salts) does not apply to it and testing is technically not feasible.
