Description of key information

Additional information

Production, handling and use of the substance only take place at a small number of industrial sites with low probability of any release from products.

Aluminium dross (ALUFLUX) contains aluminium and aluminium-based compounds.The main compounds are inorganic constituents that are insoluble in water. Due to their physico-chemical properties none of the constituents are systemically and biologically available and do not cross biological membranes. The small percentage of soluble, non-toxic salts (KCl and NaCl), pose no significant threat in terms of quantity. Only aluminum nitride reacts in contact with water and decomposes to ammonia and aluminium hydroxide at a very slow kinetically rate, which pose no significant threat in terms of amounts produced by the reaction.

In view of the chemical and physical properties of aluminium dross and its breakdown products, commercially produced aluminium dross has no potential for adsorption on soils or on suspended matter due to their very limited solubility.

According to the above mentioned data, studies to determine the biodegradation and bioaccumulation of Aluminium dross (ALUFLUX)

are not required under Regulation (EC) No 1907/2006 (REACH).
