We are looking at pilot scale to produce ointment with only 3 key substances.
What can we do to ensure product concentration, homogeneity and reproducibility? (within a batch and between batches)
Is it norm to just assume homogeneity if we use electric mixer & 3roll mill? Or we still need to get analytical tools (e.g. hegman gauge etc.) or send it to lab for expensive concentration and reproducibility tests?
What does the industry do out there?
