Here is a question for my Microbiology family members.
Do we need to do any Micro testing on a material that has low water content?
I have received a material called Lauroyl macrogolglycerid into our Micro
lab.  It is a waxy solid material. It is going into a solid oral dosage

Additional information on this material : Prior to testing the material must
be heated to 66 degree C overnight. An oven bath or oil bath is acceptable,
a steam bath is not. The sample may be kept at this temperature for upto 72
hours, stability at this condition
has been established by the supplier.
Do I have to screen for thermophilic organisms? But what is their clinical
significance? From Dr. Cundell's article most of the organisms will not
survive in products with water activity below 0.60.
