Centrifuge Test for Product Stability and Shelf Life Simulation
Question
Can the standard Centrifuge test (3,000 RPM for 30 minutes, potentially with warming to 40-45°C) be used to simulate or determine a cosmetic product's shelf life of specifically 6 months?
Answer
Regarding your question about using a centrifuge to test product stability and simulate a 6-month shelf life:
The standard centrifuge test is typically performed at 3,000 RPM for 30 minutes. An optional step for products that might be stored in warm conditions is to warm the sample to 40-45°C before centrifuging at 3,000 RPM for 30 minutes.
However, this standard test is not designed to simulate a specific shelf life like 6 months. Passing this test indicates that the cosmetic product should generally remain stable for at least 2 years, assuming no other issues such as microbial contamination.
Therefore, it is not possible to use this centrifuge test to determine or simulate a specific shelf life of only 6 months.
