Most stability and compatibility testing is carried out at elevated temperatures as an accelerated shelf life study.
The incubation conditions chosen for the test will depend upon several factors including how the product is to be warehoused, how it is to be transported and where in the world it will be marketed etc.
Melbec Microbiology have a range of ambient humidity incubators, environmental chambers and simulated light chambers and hence can cover most testing requirements with respect of temperature, humidity, simulated light and freeze thaw.
Products are assessed at each time point and assessment includes organoleptic properties, viscosity, specific gravity, weight loss, functionality and pH.
Standards used for stability and compatibility include CIPAC, PD ISO/TR 18811, IFSCC and ‘in-house’ customer specific methods.
