Custom Purification of Injectable Polymers via Carbon Dioxide Dissolution
Pierre Fabre Médicament's Supercritical division has devised a smart, good manufacturing practice (GMP) compliant and industrialised process to extract monomers from injectable polymer substances.
This innovative process fits with need of biotech / pharmaceutical companies looking for an injectable polymer with a dramatically low impurities content because of a very high dosage of polymer in formulation or an interaction with a reactive active pharmaceutical ingredient (API).
The process involves the dissolution of dense carbon dioxide (around 200bar) into a polymer until its saturation. Because of the swelling of polymer chain in dense CO2, the level of purification is very high leading to a complete extraction of monomers.
