Key value for chemical safety assessment

Additional information

According to Annex IX of REACH Regulation (EC n. 1907/2006), further biotic degradation testing is required only if the chemical safety assessment according to Annex I of REACH Regulation (EC n. 1907/2006), indicates the need to investigate further the degradation of the substance and its degradation products. Calcium Hypophosphite is inorganic and the assessment of biodegradability is scientifically unjustified.
