CAA: citric acid activity; *on ignited basis; LoI: loss on ignition.
Further grades available upon request.

According to the REACH Regulation (EC 1907/2006), magnesium oxide is exempt from registration (Annex V).
It does not contain intentionally added or relevant amounts of SVHC recently defined (published ECHA Candidate List:
echa.europa.eu/de/candidate-list-table ). Traces are possible. Since the presence of such substances in relevant
quantities cannot be expected under normal circumstances, Lehmann&Voss&Co. does not check for their absence.

Tailor-made solutions for the production of magnesia (Sorel) cement are also readiliy available.
