SOLKANE™ Pharma Propellants
Our production site in Frankfurt, formerly of Hoechst AG, has set the standard for HFA 227 in the medical world, and is the biggest manufacturer of and market leader for HFA 227 today. It can look back on more than 25 years of experience in the manufacture and supply of the MDI propellants HFA 227 for pharmaceutical aerosols. It is considered a center of competence in this field and provides support for our customers in all technical, analytical and regulatory areas.
Production of HFA 227 adheres to the stringent good manufacturing practice guidelines and continuously updated quality standards. We carry out routine quality controls at levels of less than 1 ppm for more than 60 impurities in line with CPMP/FDA guidelines.
Daikin has filed Drug Master Files for SOLKANE™ 227 pharma in all countries for cross-reference to support drug applications containing both products.
