Zephex® 227ea

Produced to our exacting, industry-leading standards, Zephex® 227ea offers performance characteristics complementary to Zephex® 134a.

It is primarily used to support heavier and denser drug suspensions such as sodium cromoglycate due to its relatively high liquid density of around 1.39 g cm^-3, whilst its lower affinity for water also means it offers improved stability when used with chemically labile actives such as formoterol.
