- Lot Availability: Once the current lot of this ingredient reaches its expiration date, will a new lot be made available for purchase to ensure continuity?
- Product Expiration: If I use this ingredient in a formulation, is it mandatory to consume the finished product before the original expiration date of the raw material?
Answer
Regarding your questions about ActiveRelease™ EGCG (Epigallocatechin Gallate 20% Encapsulation):
New Lot Availability: Generally, for active ingredients in the standard catalog, the company will restock with a new lot once the current lot is sold out or nears its expiration date to ensure continuous availability for customers.
Expiration Date and Finished Products:
- Production Timing: You must use the raw material to manufacture your product before the raw material's expiration date. You should not use expired ingredients in production.
- Finished Product Shelf Life: The expiration date of your finished product is not strictly tied to the expiration date of the raw material. Once formulated, the shelf life of the final product depends on the overall formula's stability, the effectiveness of the preservative system, and the packaging.
- Usage: You do not necessarily have to finish using the final product before the original expiration date of the raw material, provided that the product was manufactured while the ingredient was still valid and the final formula has been properly stabilized and preserved. However, for maximum efficacy, it is always best to use the freshest ingredients possible.
Storage Recommendation: To maintain the stability of this specific ingredient, please store it in the refrigerator (4°C - 8°C).
