Once the bottom degree desired to regulate growth is set, this level would be the cheapest specified limit of preservative content. The whole formula can now be tested in the stability software with confidence that given that the extent is taken care of higher than the minimum limit, development will likely be managed. This supporting info will supply a rationale to help reduced testing during security to determine shelf-existence; and could be removed from business security delivered the preservative degree is monitored chemically.
