1. What is the Accelerated Shelf Life Calculation?

The Accelerated Shelf Life calculation estimates the real shelf life of a product based on accelerated testing conditions. It uses the acceleration factor to convert results from accelerated testing to normal storage conditions.

2. How Does the Calculator Work?

The calculator uses the shelf life equation:

Where:

• Accelerated Shelf — Shelf life measured under accelerated conditions (days)
• Acceleration Factor — Factor representing how much faster degradation occurs under test conditions
• Real Shelf — Estimated shelf life under normal storage conditions (days)

Explanation: The equation converts accelerated test results to real-world shelf life predictions by accounting for the increased degradation rate under test conditions.

3. Importance of Shelf Life Estimation

Details: Accurate shelf life estimation is crucial for product development, quality control, regulatory compliance, and determining appropriate expiration dates for products.

4. Using the Calculator

Tips: Enter the shelf life measured under accelerated conditions in days and the acceleration factor. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is an acceleration factor?
A: The acceleration factor represents how much faster a product degrades under test conditions compared to normal storage conditions.

Q2: How is the acceleration factor determined?
A: The acceleration factor is typically determined through Arrhenius equation modeling or established industry standards for specific product types.

Q3: What products can use this calculation?
A: This approach is commonly used for pharmaceuticals, food products, cosmetics, and other perishable goods with predictable degradation patterns.

Q4: Are there limitations to this method?
A: This method assumes linear degradation kinetics and may not account for complex degradation pathways or unexpected environmental factors.

Q5: Should this be used for regulatory submissions?
A: While useful for initial estimates, regulatory submissions typically require more comprehensive stability studies following specific guidelines.
