Shelf Life of Skin Cream with PaeoniaPreserve™

The shelf life of a finished skin cream formulation depends on many factors, including the specific ingredients used, the manufacturing process, packaging, and storage conditions.

Regarding PaeoniaPreserve™ (Natural Preservative) itself, the product description states that the ingredient has a shelf life of at least 2 years when stored properly (at room temperature, lid tightly closed, protected from sunlight or heat).

However, this shelf life applies to the raw ingredient, not the finished cosmetic product. To determine the actual shelf life and ensure the safety and stability of a skin cream containing PaeoniaPreserve™, it is essential to perform stability testing and preservative challenge testing on the final formulation. These tests evaluate how well the preservative system protects the product from microbial contamination over time under various conditions.

Therefore, while the PaeoniaPreserve™ ingredient is stable for at least 2 years, the shelf life of your skin cream formulation must be determined through proper testing of the finished product.
