Knowledge of the “foundation” formulation susceptibility aids in identifying the extent and kind of preservative essential. The moment the lowest level desired to manage development is set, this stage will be the least expensive specified limit of preservative written content. The complete method can now be tested in The steadiness software with microbial limit test procedure self-confidence that so long as the level is preserved previously mentioned the minimal limit, expansion will be controlled. This supporting details will offer a rationale to help reduced testing for the duration of stability to determine shelf-existence; and may be eradicated from industrial steadiness offered the preservative stage is monitored chemically.
