ZINC OXIDE
GRADE AZO66EP
(Ph. Eur. and BP Commission Compliant)
Description & Uses
Grade AZO 66EP is an extremely high purity bright white zinc oxide produced from zinc metal following current Good Manufacturing Practices. AZO 66EP has been developed to meet the highest standards of chemical purity and physical quality required to meet all the requirements of the BRITISH PHARMACOPOEIA COMMISSION and PHARMACOPOEIA EUROPE. This grade can be used in pharmaceutical, cosmetic, ointment, can lacquer, and other applications specifying BP or EP quality.
