Stabilizing
active substance


 
 

EminTech 

 
  Two major routes to avoid hydrolysis of active substance are
to reduce water activity in the formulation or to use nonaqueous
hydrogen bonding.
 
  In emulsions, the discontinuous phase is
divided into smaller regions.
 
This can be utilised to avoid, or slow down,
self-catalyzing reactions like lipid oxidation,
polymerisation or crystallisation.
