Knowledge of the “foundation” formulation susceptibility aids in pinpointing the level and type of preservative desired. As soon as the lowest degree desired to control development is set, this stage will be the cheapest specified limit of preservative material. The complete system can now be tested in The soundness program with self-assurance that assuming that the extent is managed over the minimal limit, development will probably be controlled. This supporting data will offer a rationale to guidance lessened testing throughout steadiness to determine shelf-lifetime; and may be eliminated from industrial stability provided the preservative level is monitored chemically.
